Valid values are: _only_local to run the search only on shards on the local node; _local to, if possible, run the search on shards on the local node, or if not, select shards using the default method; _only_nodes:<node-id>,<node-id> to run the search on only the specified nodes IDs, where, if suitable shards exist on more than one selected node, use shards on those nodes using the default method, or if none of the specified nodes are available, select shards from any available node using the default method; _prefer_nodes:<node-id>,<node-id> to if possible, run the search on the specified nodes IDs, or if not, select shards using the default method; _shards:<shard>,<shard> to run the search only on the specified shards; <custom-string> (any string that does not start with _) to route searches with the same <custom-string> to the same shards in the same order.
    • pre_filter_shard_size (Optional, number): Defines a threshold that enforces a pre-filter roundtrip to prefilter search shards based on query rewriting if the number of shards the search request expands to exceeds the threshold. This filter roundtrip can limit the number of shards significantly if for instance a shard can not match any documents based on its rewrite method (if date filters are mandatory to match but the shard bounds and the query are disjoint). When unspecified, the pre-filter phase is executed if any of these conditions is met: the request targets more than 128 shards; the request targets one or more read-only index; the primary sort of the query targets an indexed field.
    • request_cache (Optional, boolean): If true, the caching of search results is enabled for requests where size is 0. Defaults to index level settings.

    • suggest_field (Optional, string): Specifies which field to use for suggestions.
    • suggest_mode (Optional, Enum("missing" | "popular" | "always")): Specifies the suggest mode. This parameter can only be used when the suggest_field and suggest_text query string parameters are specified.
    • suggest_size (Optional, number): Number of suggestions to return. This parameter can only be used when the suggest_field and suggest_text query string parameters are specified.
    • suggest_text (Optional, string): The source text for which the suggestions should be returned. This parameter can only be used when the suggest_field and suggest_text query string parameters are specified.
    • typed_keys (Optional, boolean): If true, aggregation and suggester names are be prefixed by their respective types in the response.
    • rest_total_hits_as_int (Optional, boolean): Indicates whether hits.total should be rendered as an integer or an object in the rest search response.
    • _source_excludes (Optional, string | string[]): A list of source fields to exclude from the response. You can also use this parameter to exclude fields from the subset specified in _source_includes query parameter. If the _source parameter is false, this parameter is ignored.
    • _source_includes (Optional, string | string[]): A list of source fields to include in the response. If this parameter is specified, only these source fields are returned. You can exclude fields from this subset using the _source_excludes query parameter. If the _source parameter is false, this parameter is ignored.
    • q (Optional, string): Query in the Lucene query string syntax using query parameter search. Query parameter searches do not support the full Elasticsearch Query DSL but are handy for testing.

Arguments

edit

  • Request (object):

    • calendar_id (string): A string that uniquely identifies a calendar.
    • job_ids (Optional, string[]): An array of anomaly detection job identifiers.
    • description (Optional, string): A description of the calendar.

put_calendar_job

edit

Adds an anomaly detection job to a calendar.

Endpoint documentation

client.ml.putCalendarJob({ calendar_id, job_id })

Arguments

edit

  • Request (object):

    • calendar_id (string): A string that uniquely identifies a calendar.
    • job_id (string): An identifier for the anomaly detection jobs. It can be a job identifier, a group name, or a list of jobs or groups.

put_data_frame_analytics

edit

Instantiates a data frame analytics job.

Endpoint documentation

client.ml.putDataFrameAnalytics({ id, analysis, dest, source })

Arguments

edit

  • Request (object):

    • id (string): Identifier for the data frame analytics job. This identifier can contain lowercase alphanumeric characters (a-z and 0-9), hyphens, and underscores. It must start and end with alphanumeric characters.
    • analysis ({ classification, outlier_detection, regression }): The analysis configuration, which contains the information necessary to perform one of the following types of analysis: classification, outlier detection, or regression.
    • dest ({ index, results_field }): The destination configuration.
    • source ({ index, query, runtime_mappings, _source }): The configuration of how to source the analysis data.
    • allow_lazy_start (Optional, boolean): Specifies whether this job can start when there is insufficient machine learning node capacity for it to be immediately assigned to a node. If set to false and a machine learning node with capacity to run the job cannot be immediately found, the API returns an error. If set to true, the API does not return an error; the job waits in the starting state until sufficient machine learning node capacity is available. This behavior is also affected by the cluster-wide xpack.ml.max_lazy_ml_nodes setting.
    • analyzed_fields (Optional, { includes, excludes }): Specifies includes and/or excludes patterns to select which fields will be included in the analysis. The patterns specified in excludes are applied last, therefore excludes takes precedence. In other words, if the same field is specified in both includes and excludes, then the field will not be included in the analysis. If analyzed_fields is not set, only the relevant fields will be included. For example, all the numeric fields for outlier detection. The supported fields vary for each type of analysis. Outlier detection requires numeric or boolean data to analyze. The algorithms don’t support missing values therefore fields that have data types other than numeric or boolean are ignored. Documents where included fields contain missing values, null values, or an array are also ignored. Therefore the dest index may contain documents that don’t have an outlier score. Regression supports fields that are numeric, boolean, text, keyword, and ip data types. It is also tolerant of missing values. Fields that are supported are included in the analysis, other fields are ignored. Documents where included fields contain an array with two or more values are also ignored. Documents in the dest index that don’t contain a results field are not included in the regression analysis. Classification supports fields that are numeric, boolean, text, keyword, and ip data types. It is also tolerant of missing values. Fields that are supported are included in the analysis, other fields are ignored. Documents where included fields contain an array with two or more values are also ignored. Documents in the dest index that don’t contain a results field are not included in the classification analysis. Classification analysis can be improved by mapping ordinal variable values to a single number. For example, in case of age ranges, you can model the values as 0-14 = 0, 15-24 = 1, 25-34 = 2, and so on.
    • description (Optional, string): A description of the job.
    • max_num_threads (Optional, number): The maximum number of threads to be used by the analysis. Using more threads may decrease the time necessary to complete the analysis at the cost of using more CPU. Note that the process may use additional threads for operational functionality other than the analysis itself.
    • model_memory_limit (Optional, string): The approximate maximum amount of memory resources that are permitted for analytical processing. If your elasticsearch.yml file contains an xpack.ml.max_model_memory_limit setting, an error occurs when you try to create data frame analytics jobs that have model_memory_limit values greater than that setting.
    • headers (Optional, Record<string, string | string[]>)
    • version (Optional, string)

put_datafeed

edit

Instantiates a datafeed.

Endpoint documentation

client.ml.putDatafeed({ datafeed_id })

Arguments

edit

  • Request (object):

    • datafeed_id (string): A numerical character string that uniquely identifies the datafeed. This identifier can contain lowercase alphanumeric characters (a-z and 0-9), hyphens, and underscores. It must start and end with alphanumeric characters.
    • aggregations (Optional, Record<string, { aggregations, meta, adjacency_matrix, auto_date_histogram, avg, avg_bucket, boxplot, bucket_script, bucket_selector, bucket_sort, bucket_count_ks_test, bucket_correlation, cardinality, categorize_text, children, composite, cumulative_cardinality, cumulative_sum, date_histogram, date_range, derivative, diversified_sampler, extended_stats, extended_stats_bucket, frequent_item_sets, filter, filters, geo_bounds, geo_centroid, geo_distance, geohash_grid, geo_line, geotile_grid, geohex_grid, global, histogram, ip_range, ip_prefix, inference, line, matrix_stats, max, max_bucket, median_absolute_deviation, min, min_bucket, missing, moving_avg, moving_percentiles, moving_fn, multi_terms, nested, normalize, parent, percentile_ranks, percentiles, percentiles_bucket, range, rare_terms, rate, reverse_nested, sampler, scripted_metric, serial_diff, significant_terms, significant_text, stats, stats_bucket, string_stats, sum, sum_bucket, terms, top_hits, t_test, top_metrics, value_count, weighted_avg, variable_width_histogram }>): If set, the datafeed performs aggregation searches. Support for aggregations is limited and should be used only with low cardinality data.
    • chunking_config (Optional, { mode, time_span }): Datafeeds might be required to search over long time periods, for several months or years. This search is split into time chunks in order to ensure the load on Elasticsearch is managed. Chunking configuration controls how the size of these time chunks are calculated; it is an advanced configuration option.
    • delayed_data_check_config (Optional, { check_window, enabled }): Specifies whether the datafeed checks for missing data and the size of the window. The datafeed can optionally search over indices that have already been read in an effort to determine whether any data has subsequently been added to the index. If missing data is found, it is a good indication that the query_delay is set too low and the data is being indexed after the datafeed has passed that moment in time. This check runs only on real-time datafeeds.
    • frequency (Optional, string | -1 | 0): The interval at which scheduled queries are made while the datafeed runs in real time. The default value is either the bucket span for short bucket spans, or, for longer bucket spans, a sensible fraction of the bucket span. When frequency is shorter than the bucket span, interim results for the last (partial) bucket are written then eventually overwritten by the full bucket results. If the datafeed uses aggregations, this value must be divisible by the interval of the date histogram aggregation.
    • indices (Optional, string | string[]): An array of index names. Wildcards are supported. If any of the indices are in remote clusters, the machine learning nodes must have the remote_cluster_client role.
    • indices_options (Optional, { allow_no_indices, expand_wildcards, ignore_unavailable, ignore_throttled }): Specifies index expansion options that are used during search
    • job_id (Optional, string): Identifier for the anomaly detection job.
    • max_empty_searches (Optional, number): If a real-time datafeed has never seen any data (including during any initial training period), it automatically stops and closes the associated job after this many real-time searches return no documents. In other words, it stops after frequency times max_empty_searches of real-time operation. If not set, a datafeed with no end time that sees no data remains started until it is explicitly stopped. By default, it is not set.
    • query (Optional, { bool, boosting, common, combined_fields, constant_score, dis_max, distance_feature, exists, function_score, fuzzy, geo_bounding_box, geo_distance, geo_polygon, geo_shape, has_child, has_parent, ids, intervals, match, match_all, match_bool_prefix, match_none, match_phrase, match_phrase_prefix, more_like_this, multi_match, nested, parent_id, percolate, pinned, prefix, query_string, range, rank_feature, regexp, rule_query, script, script_score, shape, simple_query_string, span_containing, field_masking_span, span_first, span_multi, span_near, span_not, span_or, span_term, span_within, term, terms, terms_set, text_expansion, wildcard, wrapper, type }): The Elasticsearch query domain-specific language (DSL). This value corresponds to the query object in an Elasticsearch search POST body. All the options that are supported by Elasticsearch can be used, as this object is passed verbatim to Elasticsearch.
    • query_delay (Optional, string | -1 | 0): The number of seconds behind real time that data is queried. For example, if data from 10:04 a.m. might not be searchable in Elasticsearch until 10:06 a.m., set this property to 120 seconds. The default value is randomly selected between 60s and 120s. This randomness improves the query performance when there are multiple jobs running on the same node.
    • runtime_mappings (Optional, Record<string, { fetch_fields, format, input_field, target_field, target_index, script, type }>): Specifies runtime fields for the datafeed search.
    • script_fields (Optional, Record<string, { script, ignore_failure }>): Specifies scripts that evaluate custom expressions and returns script fields to the datafeed. The detector configuration objects in a job can contain functions that use these script fields.
    • scroll_size (Optional, number): The size parameter that is used in Elasticsearch searches when the datafeed does not use aggregations. The maximum value is the value of index.max_result_window, which is 10,000 by default.
    • headers (Optional, Record<string, string | string[]>)
    • allow_no_indices (Optional, boolean): If true, wildcard indices expressions that resolve into no concrete indices are ignored. This includes the _all string or when no indices are specified.
    • expand_wildcards (Optional, Enum("all" | "open" | "closed" | "hidden" | "none") | Enum("all" | "open" | "closed" | "hidden" | "none")[]): Type of index that wildcard patterns can match. If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams. Supports a list of values.
    • ignore_throttled (Optional, boolean): If true, concrete, expanded, or aliased indices are ignored when frozen.
    • ignore_unavailable (Optional, boolean): If true, unavailable indices (missing or closed) are ignored.

put_filter

edit

    • description (Optional, string): A description of the filter.
    • items (Optional, string[]): The items of the filter. A wildcard * can be used at the beginning or the end of an item. Up to 10000 items are allowed in each filter.

put_job

edit

Instantiates an anomaly detection job.

Endpoint documentation

client.ml.putJob({ job_id, analysis_config, data_description })

Arguments

edit

  • Request (object):

    • job_id (string): The identifier for the anomaly detection job. This identifier can contain lowercase alphanumeric characters (a-z and 0-9), hyphens, and underscores. It must start and end with alphanumeric characters.
    • analysis_config ({ bucket_span, categorization_analyzer, categorization_field_name, categorization_filters, detectors, influencers, latency, model_prune_window, multivariate_by_fields, per_partition_categorization, summary_count_field_name }): Specifies how to analyze the data. After you create a job, you cannot change the analysis configuration; all the properties are informational.
    • data_description ({ format, time_field, time_format, field_delimiter }): Defines the format of the input data when you send data to the job by using the post data API. Note that when configure a datafeed, these properties are automatically set. When data is received via the post data API, it is not stored in Elasticsearch. Only the results for anomaly detection are retained.
    • allow_lazy_open (Optional, boolean): Advanced configuration option. Specifies whether this job can open when there is insufficient machine learning node capacity for it to be immediately assigned to a node. By default, if a machine learning node with capacity to run the job cannot immediately be found, the open anomaly detection jobs API returns an error. However, this is also subject to the cluster-wide xpack.ml.max_lazy_ml_nodes setting. If this option is set to true, the open anomaly detection jobs API does not return an error and the job waits in the opening state until sufficient machine learning node capacity is available.
    • analysis_limits (Optional, { categorization_examples_limit, model_memory_limit }): Limits can be applied for the resources required to hold the mathematical models in memory. These limits are approximate and can be set per job. They do not control the memory used by other processes, for example the Elasticsearch Java processes.
    • background_persist_interval (Optional, string | -1 | 0): Advanced configuration option. The time between each periodic persistence of the model. The default value is a randomized value between 3 to 4 hours, which avoids all jobs persisting at exactly the same time. The smallest allowed value is 1 hour. For very large models (several GB), persistence could take 10-20 minutes, so do not set the background_persist_interval value too low.
    • custom_settings (Optional, User-defined value): Advanced configuration option. Contains custom meta data about the job.
    • daily_model_snapshot_retention_after_days (Optional, number): Advanced configuration option, which affects the automatic removal of old model snapshots for this job. It specifies a period of time (in days) after which only the first snapshot per day is retained. This period is relative to the timestamp of the most recent snapshot for this job. Valid values range from 0 to model_snapshot_retention_days.
    • datafeed_config (Optional, { aggregations, chunking_config, datafeed_id, delayed_data_check_config, frequency, indices, indices_options, job_id, max_empty_searches, query, query_delay, runtime_mappings, script_fields, scroll_size }): Defines a datafeed for the anomaly detection job. If Elasticsearch security features are enabled, your datafeed remembers which roles the user who created it had at the time of creation and runs the query using those same roles. If you provide secondary authorization headers, those credentials are used instead.
    • description (Optional, string): A description of the job.
    • groups (Optional, string[]): A list of job groups. A job can belong to no groups or many.
    • model_plot_config (Optional, { annotations_enabled, enabled, terms }): This advanced configuration option stores model information along with the results. It provides a more detailed view into anomaly detection. If you enable model plot it can add considerable overhead to the performance of the system; it is not feasible for jobs with many entities. Model plot provides a simplified and indicative view of the model and its bounds. It does not display complex features such as multivariate correlations or multimodal data. As such, anomalies may occasionally be reported which cannot be seen in the model plot. Model plot config can be configured when the job is created or updated later. It must be disabled if performance issues are experienced.
    • model_snapshot_retention_days (Optional, number): Advanced configuration option, which affects the automatic removal of old model snapshots for this job. It specifies the maximum period of time (in days) that snapshots are retained. This period is relative to the timestamp of the most recent snapshot for this job. By default, snapshots ten days older than the newest snapshot are deleted.
    • renormalization_window_days (Optional, number): Advanced configuration option. The period over which adjustments to the score are applied, as new data is seen. The default value is the longer of 30 days or 100 bucket spans.
    • results_index_name (Optional, string): A text string that affects the name of the machine learning results index. By default, the job generates an index named .ml-anomalies-shared.
    • results_retention_days (Optional, number): Advanced configuration option. The period of time (in days) that results are retained. Age is calculated relative to the timestamp of the latest bucket result. If this property has a non-null value, once per day at 00:30 (server time), results that are the specified number of days older than the latest bucket result are deleted from Elasticsearch. The default value is null, which means all results are retained. Annotations generated by the system also count as results for retention purposes; they are deleted after the same number of days as results. Annotations added by users are retained forever.

    • platform_architecture (Optional, string): The platform architecture (if applicable) of the trained mode. If the model only works on one platform, because it is heavily optimized for a particular processor architecture and OS combination, then this field specifies which. The format of the string must match the platform identifiers used by Elasticsearch, so one of, linux-x86_64, linux-aarch64, darwin-x86_64, darwin-aarch64, or windows-x86_64.

Arguments

edit

  • Request (object):

    • job_id (string): Identifier for the anomaly detection job.
    • snapshot_id (string): You can specify empty as the <snapshot_id>. Reverting to the empty snapshot means the anomaly detection job starts learning a new model from scratch when it is started.
    • delete_intervening_results (Optional, boolean): Refer to the description for the delete_intervening_results query parameter.

set_upgrade_mode

edit

Sets a cluster wide upgrade_mode setting that prepares machine learning indices for an upgrade.

    • deployment_id (Optional, string): A unique identifier for the deployment of the model.
    • number_of_allocations (Optional, number): The number of model allocations on each node where the model is deployed. All allocations on a node share the same copy of the model in memory but use a separate set of threads to evaluate the model. Increasing this value generally increases the throughput.

    • threads_per_allocation (Optional, number): Sets the number of threads used by each model allocation during inference. This generally increases the inference speed. The inference process is a compute-bound process; any number greater than the number of available hardware threads on the machine does not increase the inference speed. If this setting is greater than the number of hardware threads it will automatically be changed to a value less than the number of hardware threads.
    • timeout (Optional, string | -1 | 0): Specifies the amount of time to wait for the model to deploy.

    • max_num_threads (Optional, number): The maximum number of threads to be used by the analysis. Using more threads may decrease the time necessary to complete the analysis at the cost of using more CPU. Note that the process may use additional threads for operational functionality other than the analysis itself.
    • allow_lazy_start (Optional, boolean): Specifies whether this job can start when there is insufficient machine learning node capacity for it to be immediately assigned to a node.

update_datafeed

edit

Updates certain properties of a datafeed.

Endpoint documentation

client.ml.updateDatafeed({ datafeed_id })

Arguments

edit

  • Request (object):

    • datafeed_id (string): A numerical character string that uniquely identifies the datafeed. This identifier can contain lowercase alphanumeric characters (a-z and 0-9), hyphens, and underscores. It must start and end with alphanumeric characters.
    • aggregations (Optional, Record<string, { aggregations, meta, adjacency_matrix, auto_date_histogram, avg, avg_bucket, boxplot, bucket_script, bucket_selector, bucket_sort, bucket_count_ks_test, bucket_correlation, cardinality, categorize_text, children, composite, cumulative_cardinality, cumulative_sum, date_histogram, date_range, derivative, diversified_sampler, extended_stats, extended_stats_bucket, frequent_item_sets, filter, filters, geo_bounds, geo_centroid, geo_distance, geohash_grid, geo_line, geotile_grid, geohex_grid, global, histogram, ip_range, ip_prefix, inference, line, matrix_stats, max, max_bucket, median_absolute_deviation, min, min_bucket, missing, moving_avg, moving_percentiles, moving_fn, multi_terms, nested, normalize, parent, percentile_ranks, percentiles, percentiles_bucket, range, rare_terms, rate, reverse_nested, sampler, scripted_metric, serial_diff, significant_terms, significant_text, stats, stats_bucket, string_stats, sum, sum_bucket, terms, top_hits, t_test, top_metrics, value_count, weighted_avg, variable_width_histogram }>): If set, the datafeed performs aggregation searches. Support for aggregations is limited and should be used only with low cardinality data.
    • chunking_config (Optional, { mode, time_span }): Datafeeds might search over long time periods, for several months or years. This search is split into time chunks in order to ensure the load on Elasticsearch is managed. Chunking configuration controls how the size of these time chunks are calculated; it is an advanced configuration option.
    • delayed_data_check_config (Optional, { check_window, enabled }): Specifies whether the datafeed checks for missing data and the size of the window. The datafeed can optionally search over indices that have already been read in an effort to determine whether any data has subsequently been added to the index. If missing data is found, it is a good indication that the query_delay is set too low and the data is being indexed after the datafeed has passed that moment in time. This check runs only on real-time datafeeds.
    • frequency (Optional, string | -1 | 0): The interval at which scheduled queries are made while the datafeed runs in real time. The default value is either the bucket span for short bucket spans, or, for longer bucket spans, a sensible fraction of the bucket span. When frequency is shorter than the bucket span, interim results for the last (partial) bucket are written then eventually overwritten by the full bucket results. If the datafeed uses aggregations, this value must be divisible by the interval of the date histogram aggregation.
    • indices (Optional, string[]): An array of index names. Wildcards are supported. If any of the indices are in remote clusters, the machine learning nodes must have the remote_cluster_client role.
    • indices_options (Optional, { allow_no_indices, expand_wildcards, ignore_unavailable, ignore_throttled }): Specifies index expansion options that are used during search.
    • job_id (Optional, string)
    • max_empty_searches (Optional, number): If a real-time datafeed has never seen any data (including during any initial training period), it automatically stops and closes the associated job after this many real-time searches return no documents. In other words, it stops after frequency times max_empty_searches of real-time operation. If not set, a datafeed with no end time that sees no data remains started until it is explicitly stopped. By default, it is not set.
    • query (Optional, { bool, boosting, common, combined_fields, constant_score, dis_max, distance_feature, exists, function_score, fuzzy, geo_bounding_box, geo_distance, geo_polygon, geo_shape, has_child, has_parent, ids, intervals, match, match_all, match_bool_prefix, match_none, match_phrase, match_phrase_prefix, more_like_this, multi_match, nested, parent_id, percolate, pinned, prefix, query_string, range, rank_feature, regexp, rule_query, script, script_score, shape, simple_query_string, span_containing, field_masking_span, span_first, span_multi, span_near, span_not, span_or, span_term, span_within, term, terms, terms_set, text_expansion, wildcard, wrapper, type }): The Elasticsearch query domain-specific language (DSL). This value corresponds to the query object in an Elasticsearch search POST body. All the options that are supported by Elasticsearch can be used, as this object is passed verbatim to Elasticsearch. Note that if you change the query, the analyzed data is also changed. Therefore, the time required to learn might be long and the understandability of the results is unpredictable. If you want to make significant changes to the source data, it is recommended that you clone the job and datafeed and make the amendments in the clone. Let both run in parallel and close one when you are satisfied with the results of the job.
    • query_delay (Optional, string | -1 | 0): The number of seconds behind real time that data is queried. For example, if data from 10:04 a.m. might not be searchable in Elasticsearch until 10:06 a.m., set this property to 120 seconds. The default value is randomly selected between 60s and 120s. This randomness improves the query performance when there are multiple jobs running on the same node.
    • runtime_mappings (Optional, Record<string, { fetch_fields, format, input_field, target_field, target_index, script, type }>): Specifies runtime fields for the datafeed search.
    • script_fields (Optional, Record<string, { script, ignore_failure }>): Specifies scripts that evaluate custom expressions and returns script fields to the datafeed. The detector configuration objects in a job can contain functions that use these script fields.
    • scroll_size (Optional, number): The size parameter that is used in Elasticsearch searches when the datafeed does not use aggregations. The maximum value is the value of index.max_result_window.
    • allow_no_indices (Optional, boolean): If true, wildcard indices expressions that resolve into no concrete indices are ignored. This includes the _all string or when no indices are specified.
    • expand_wildcards (Optional, Enum("all" | "open" | "closed" | "hidden" | "none") | Enum("all" | "open" | "closed" | "hidden" | "none")[]): Type of index that wildcard patterns can match. If the request can target data streams, this argument determines whether wildcard expressions match hidden data streams. Supports a list of values. Valid values are:
  • all: Match any data stream or index, including hidden ones.
  • closed: Match closed, non-hidden indices. Also matches any non-hidden data stream. Data streams cannot be closed.
  • hidden: Match hidden data streams and hidden indices. Must be combined with open, closed, or both.
  • none: Wildcard patterns are not accepted.

  • open: Match open, non-hidden indices. Also matches any non-hidden data stream.

    • ignore_throttled (Optional, boolean): If true, concrete, expanded or aliased indices are ignored when frozen.
    • ignore_unavailable (Optional, boolean): If true, unavailable indices (missing or closed) are ignored.

update_filter

Endpoint documentation

client.ml.updateJob({ job_id })

Arguments

edit

  • Request (object):

    • job_id (string): Identifier for the job.
    • allow_lazy_open (Optional, boolean): Advanced configuration option. Specifies whether this job can open when there is insufficient machine learning node capacity for it to be immediately assigned to a node. If false and a machine learning node with capacity to run the job cannot immediately be found, the open anomaly detection jobs API returns an error. However, this is also subject to the cluster-wide xpack.ml.max_lazy_ml_nodes setting. If this option is set to true, the open anomaly detection jobs API does not return an error and the job waits in the opening state until sufficient machine learning node capacity is available.
    • analysis_limits (Optional, { model_memory_limit })
    • background_persist_interval (Optional, string | -1 | 0): Advanced configuration option. The time between each periodic persistence of the model. The default value is a randomized value between 3 to 4 hours, which avoids all jobs persisting at exactly the same time. The smallest allowed value is 1 hour. For very large models (several GB), persistence could take 10-20 minutes, so do not set the value too low. If the job is open when you make the update, you must stop the datafeed, close the job, then reopen the job and restart the datafeed for the changes to take effect.
    • custom_settings (Optional, Record<string, User-defined value>): Advanced configuration option. Contains custom meta data about the job. For example, it can contain custom URL information as shown in Adding custom URLs to machine learning results.
    • categorization_filters (Optional, string[])
    • description (Optional, string): A description of the job.
    • model_plot_config (Optional, { annotations_enabled, enabled, terms })
    • model_prune_window (Optional, string | -1 | 0)
    • daily_model_snapshot_retention_after_days (Optional, number): Advanced configuration option, which affects the automatic removal of old model snapshots for this job. It specifies a period of time (in days) after which only the first snapshot per day is retained. This period is relative to the timestamp of the most recent snapshot for this job. Valid values range from 0 to model_snapshot_retention_days. For jobs created before version 7.8.0, the default value matches model_snapshot_retention_days.
    • model_snapshot_retention_days (Optional, number): Advanced configuration option, which affects the automatic removal of old model snapshots for this job. It specifies the maximum period of time (in days) that snapshots are retained. This period is relative to the timestamp of the most recent snapshot for this job.
    • renormalization_window_days (Optional, number): Advanced configuration option. The period over which adjustments to the score are applied, as new data is seen.
    • results_retention_days (Optional, number): Advanced configuration option. The period of time (in days) that results are retained. Age is calculated relative to the timestamp of the latest bucket result. If this property has a non-null value, once per day at 00:30 (server time), results that are the specified number of days older than the latest bucket result are deleted from Elasticsearch. The default value is null, which means all results are retained.
    • groups (Optional, string[]): A list of job groups. A job can belong to no groups or many.
    • detectors (Optional, { by_field_name, custom_rules, detector_description, detector_index, exclude_frequent, field_name, function, over_field_name, partition_field_name, use_null }[]): An array of detector update objects.
    • per_partition_categorization (Optional, { enabled, stop_on_warn }): Settings related to how categorization interacts with partition fields.

put_job

edit

Creates a rollup job.

Endpoint documentation

client.rollup.putJob({ id, cron, groups, index_pattern, page_size, rollup_index })

Arguments

edit

  • Request (object):

    • id (string): Identifier for the rollup job. This can be any alphanumeric string and uniquely identifies the data that is associated with the rollup job. The ID is persistent; it is stored with the rolled up data. If you create a job, let it run for a while, then delete the job, the data that the job rolled up is still be associated with this job ID. You cannot create a new job with the same ID since that could lead to problems with mismatched job configurations.
    • cron (string): A cron string which defines the intervals when the rollup job should be executed. When the interval triggers, the indexer attempts to rollup the data in the index pattern. The cron pattern is unrelated to the time interval of the data being rolled up. For example, you may wish to create hourly rollups of your document but to only run the indexer on a daily basis at midnight, as defined by the cron. The cron pattern is defined just like a Watcher cron schedule.
    • groups ({ date_histogram, histogram, terms }): Defines the grouping fields and aggregations that are defined for this rollup job. These fields will then be available later for aggregating into buckets. These aggs and fields can be used in any combination. Think of the groups configuration as defining a set of tools that can later be used in aggregations to partition the data. Unlike raw data, we have to think ahead to which fields and aggregations might be used. Rollups provide enough flexibility that you simply need to determine which fields are needed, not in what order they are needed.
    • index_pattern (string): The index or index pattern to roll up. Supports wildcard-style patterns (logstash-*). The job attempts to rollup the entire index or index-pattern.
    • page_size (number): The number of bucket results that are processed on each iteration of the rollup indexer. A larger value tends to execute faster, but requires more memory during processing. This value has no effect on how the data is rolled up; it is merely used for tweaking the speed or memory cost of the indexer.
    • rollup_index (string): The index that contains the rollup results. The index can be shared with other rollup jobs. The data is stored so that it doesn’t interfere with unrelated jobs.
    • metrics (Optional, { field, metrics }[]): Defines the metrics to collect for each grouping tuple. By default, only the doc_counts are collected for each group. To make rollup useful, you will often add metrics like averages, mins, maxes, etc. Metrics are defined on a per-field basis and for each field you configure which metric should be collected.
    • timeout (Optional, string | -1 | 0): Time to wait for the request to complete.
    • headers (Optional, Record<string, string | string[]>)

    • query (Optional, { bool, boosting, common, combined_fields, constant_score, dis_max, distance_feature, exists, function_score, fuzzy, geo_bounding_box, geo_distance, geo_polygon, geo_shape, has_child, has_parent, ids, intervals, match, match_all, match_bool_prefix, match_none, match_phrase, match_phrase_prefix, more_like_this, multi_match, nested, parent_id, percolate, pinned, prefix, query_string, range, rank_feature, regexp, rule_query, script, script_score, shape, simple_query_string, span_containing, field_masking_span, span_first, span_multi, span_near, span_not, span_or, span_term, span_within, term, terms, terms_set, text_expansion, wildcard, wrapper, type }): Specifies a DSL query.
    • size (Optional, number): Must be zero if set, as rollups work on pre-aggregated data.
    • rest_total_hits_as_int (Optional, boolean): Indicates whether hits.total should be rendered as an integer or an object in the rest search response
    • typed_keys (Optional, boolean): Specify whether aggregation and suggester names should be prefixed by their respective types in the response

Arguments

edit

  • Request (object):

    • text_files (Optional, TJsonDocument[])
    • charset (Optional, string): The text’s character set. It must be a character set that is supported by the JVM that Elasticsearch uses. For example, UTF-8, UTF-16LE, windows-1252, or EUC-JP. If this parameter is not specified, the structure finder chooses an appropriate character set.
    • column_names (Optional, string): If you have set format to delimited, you can specify the column names in a list. If this parameter is not specified, the structure finder uses the column names from the header row of the text. If the text does not have a header role, columns are named "column1", "column2", "column3", etc.
    • delimiter (Optional, string): If you have set format to delimited, you can specify the character used to delimit the values in each row. Only a single character is supported; the delimiter cannot have multiple characters. By default, the API considers the following possibilities: comma, tab, semi-colon, and pipe (|). In this default scenario, all rows must have the same number of fields for the delimited format to be detected. If you specify a delimiter, up to 10% of the rows can have a different number of columns than the first row.
    • explain (Optional, boolean): If this parameter is set to true, the response includes a field named explanation, which is an array of strings that indicate how the structure finder produced its result.
    • format (Optional, string): The high level structure of the text. Valid values are ndjson, xml, delimited, and semi_structured_text. By default, the API chooses the format. In this default scenario, all rows must have the same number of fields for a delimited format to be detected. If the format is set to delimited and the delimiter is not set, however, the API tolerates up to 5% of rows that have a different number of columns than the first row.
    • grok_pattern (Optional, string): If you have set format to semi_structured_text, you can specify a Grok pattern that is used to extract fields from every message in the text. The name of the timestamp field in the Grok pattern must match what is specified in the timestamp_field parameter. If that parameter is not specified, the name of the timestamp field in the Grok pattern must match "timestamp". If grok_pattern is not specified, the structure finder creates a Grok pattern.
    • has_header_row (Optional, boolean): If you have set format to delimited, you can use this parameter to indicate whether the column names are in the first row of the text. If this parameter is not specified, the structure finder guesses based on the similarity of the first row of the text to other rows.
    • line_merge_size_limit (Optional, number): The maximum number of characters in a message when lines are merged to form messages while analyzing semi-structured text. If you have extremely long messages you may need to increase this, but be aware that this may lead to very long processing times if the way to group lines into messages is misdetected.
    • lines_to_sample (Optional, number): The number of lines to include in the structural analysis, starting from the beginning of the text. The minimum is 2; If the value of this parameter is greater than the number of lines in the text, the analysis proceeds (as long as there are at least two lines in the text) for all of the lines.
    • quote (Optional, string): If you have set format to delimited, you can specify the character used to quote the values in each row if they contain newlines or the delimiter character. Only a single character is supported. If this parameter is not specified, the default value is a double quote (").
