The following are the _expert-level_ settings available for configuring an internal diagnostics service.
|
|
The output of this service is currently exposed through the Health API <<health-api, Health API>>. It
|
|
is not recommended to change any of these from their default values.
|
|
|
|
==== Cluster level settings
|
|
|
|
`health.master_history.has_master_lookup_timeframe`::
|
|
(<<static-cluster-setting,Static>>) The amount of time a node looks back to see if it has observed
|
|
a master at all, before moving on with other checks. Defaults to `30s` (30 seconds).
|
|
|
|
`master_history.max_age`::
|
|
(<<static-cluster-setting,Static>>) The timeframe we record the master history
|
|
to be used for diagnosing the cluster health. Master node changes older than this time will not be considered when
|
|
diagnosing the cluster health. Defaults to `30m` (30 minutes).
|
|
|
|
`health.master_history.identity_changes_threshold`::
|
|
(<<static-cluster-setting,Static>>) The number of master identity changes witnessed by a node that indicates the cluster is not healthy.
|
|
Defaults to `4`.
|
|
|
|
`health.master_history.no_master_transitions_threshold`::
|
|
(<<static-cluster-setting,Static>>) The number of transitions to no master witnessed by a node that indicates the cluster is not healthy.
|
|
Defaults to `4`.
|
|
|
|
`health.node.enabled`::
|
|
(<<cluster-update-settings,Dynamic>>) Enables the health node, which allows the health API to provide indications about
|
|
cluster wide health aspects such as disk space.
|
|
|
|
`health.reporting.local.monitor.interval`::
|
|
(<<cluster-update-settings,Dynamic>>) Determines the interval in which each node of the cluster monitors aspects that
|
|
comprise its local health such as its disk usage.
|
|
|
|
`health.ilm.max_time_on_action`::
|
|
(<<cluster-update-settings,Dynamic>>) The minimum amount of time an index has to be in an {ilm} ({ilm-init}) action before it is considered stagnant. Defaults to `1d` (1 day).
|
|
|
|
`health.ilm.max_time_on_step`::
|
|
(<<cluster-update-settings,Dynamic>>) The minimum amount of time an index has to be in an {ilm-init} step before it is considered stagnant. Defaults to `1d` (1 day).
|
|
|
|
`health.ilm.max_retries_per_step`::
|
|
(<<cluster-update-settings,Dynamic>>) The minimum amount of times an index has retried by an {ilm-init} step before it is considered stagnant. Defaults to `100`
|
|
|
|
`health.periodic_logger.enabled`::
|
|
(<<cluster-update-settings,Dynamic>>) Enables the health periodic logger, which logs the health statuses of each health indicator along with the top level one as observed by the Health API.
|
|
Defaults to `false`.
|
|
|
|
`health.periodic_logger.poll_interval`::
|
|
(<<cluster-update-settings,Dynamic>>, <<time-units, time unit value>>) How often {es} logs the health status of the cluster and of each health indicator as observed by the Health API.
|
|
Defaults to `60s` (60 seconds).
