Task Manager settings in Kibana
editTask Manager settings in Kibana
editTask Manager runs background tasks by polling for work on an interval. You can configure its behavior to tune for performance and throughput.
Task Manager settings
edit-
xpack.task_manager.max_attempts - The maximum number of times a task will be attempted before being abandoned as failed. Defaults to 3.
-
xpack.task_manager.poll_interval - How often, in milliseconds, the task manager will look for more work. Defaults to 3000 and cannot be lower than 100.
-
xpack.task_manager.request_capacity - How many requests can Task Manager buffer before it rejects new requests. Defaults to 1000.
-
xpack.task_manager.index -
The name of the index used to store task information. Defaults to
.kibana_task_manager. -
xpack.task_manager.max_workers - The maximum number of tasks that this Kibana instance will run simultaneously. Defaults to 10. Starting in 8.0, it will not be possible to set the value greater than 100.
-
xpack.task_manager.monitored_stats_health_verbose_log.enabled - This flag will enable automatic warn and error logging if task manager self detects a performance issue, such as the time between when a task is scheduled to execute and when it actually executes. Defaults to false.
-
xpack.task_manager.monitored_stats_health_verbose_log.warn_delayed_task_start_in_seconds - The amount of seconds we allow a task to delay before printing a warning server log. Defaults to 60.
Task Manager Health settings
editSettings that configure the Health monitoring endpoint.
-
xpack.task_manager.monitored_task_execution_thresholds -
Configures the threshold of failed task executions at which point the
warnorerrorhealth status is set under each task type execution status (understats.runtime.value.execution.result_frequency_percent_as_number[${task type}].status).This setting allows configuration of both the default level and a custom task type specific level. By default, this setting is configured to mark the health of every task type as
warningwhen it exceeds 80% failed executions, and aserrorat 90%.Custom configurations allow you to reduce this threshold to catch failures sooner for task types that you might consider critical, such as alerting tasks.
This value can be set to any number between 0 to 100, and a threshold is hit when the value exceeds this number. This means that you can avoid setting the status to
errorby setting the threshold at 100, or hiterrorthe moment any task fails by setting the threshold to 0 (as it will exceed 0 once a single failure occurs).
