influxdb

edit

This is a community-maintained plugin! It does not ship with Logstash by default, but it is easy to install by running bin/logstash-plugin install logstash-output-influxdb.

This output lets you output Metrics to InfluxDB (>= 0.9.0-rc31)

The configuration here attempts to be as friendly as possible and minimize the need for multiple definitions to write to multiple measurements and still be efficient

the InfluxDB API let’s you do some semblance of bulk operation per http call but each call is database-specific

You can learn more at InfluxDB homepage

Details

edit

`allow_time_override`

edit

Value type is boolean
Default value is false

Allow the override of the time column in the event?

By default any column with a name of time will be ignored and the time will be determined by the value of @timestamp.

Setting this to true allows you to explicitly set the time column yourself

Note: time must be an epoch value in either seconds, milliseconds or microseconds

`codec`

edit

Value type is codec
Default value is "plain"

The codec used for output data. Output codecs are a convenient method for encoding your data before it leaves the output, without needing a separate filter in your Logstash pipeline.

`coerce_values`

edit

Value type is hash
Default value is {}

Allow value coercion

this will attempt to convert data point values to the appropriate type before posting otherwise sprintf-filtered numeric values could get sent as strings format is {'column_name' => 'datatype'}

currently supported datatypes are integer and float

`data_points`

edit

This is a required setting.
Value type is hash
Default value is {}

Hash of key/value pairs representing data points to send to the named database Example: {'column1' => 'value1', 'column2' => 'value2'}

Events for the same measurement will be batched together where possible Both keys and values support sprintf formatting

`db`

edit

Value type is string
Default value is "statistics"

The database to write

`exclude_fields`

edit

Value type is array
Default value is ["@timestamp", "@version", "sequence", "message", "type"]

An array containing the names of fields from the event to exclude from the data points

Events, in general, contain keys "@version" and "@timestamp". Other plugins may add others that you’ll want to exclude (such as "command" from the exec plugin).

This only applies when use_event_fields_for_data_points is true.

`flush_size`

edit

Value type is number
Default value is 100

This setting controls how many events will be buffered before sending a batch of events. Note that these are only batched for the same measurement

`host`

edit

This is a required setting.
Value type is string
There is no default value for this setting.

The hostname or IP address to reach your InfluxDB instance

`idle_flush_time`

edit

Value type is number
Default value is 1

The amount of time since last flush before a flush is forced.

This setting helps ensure slow event rates don’t get stuck in Logstash. For example, if your flush_size is 100, and you have received 10 events, and it has been more than idle_flush_time seconds since the last flush, logstash will flush those 10 events automatically.

This helps keep both fast and slow log streams moving along in near-real-time.

`measurement`

edit

Value type is string
Default value is "logstash"

Measurement name - supports sprintf formatting

`password`

edit

Value type is password
Default value is nil

The password for the user who access to the named database

`port`

edit

Value type is number
Default value is 8086

The port for InfluxDB

`retention_policy`

edit

Value type is string
Default value is "default"

The retention policy to use

`send_as_tags`

edit

Value type is array
Default value is ["host"]

An array containing the names of fields to send to Influxdb as tags instead of fields. Influxdb 0.9 convention is that values that do not change every request should be considered metadata and given as tags.
