Health diagnostic settings in Elasticsearch
editHealth diagnostic settings in Elasticsearch
editThe 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. It is not recommended to change any of these from their default values.
Cluster level settings
edit-
health.master_history.has_master_lookup_timeframe -
(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) 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) 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) The number of transitions to no master witnessed by a node that indicates the cluster is not healthy.
Defaults to
4. -
health.node.enabled - (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 - (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 -
(Dynamic) The minimum amount of time an index has to be in an index lifecycle management (ILM) action before it is considered stagnant. Defaults to
1d(1 day). -
health.ilm.max_time_on_step -
(Dynamic) The minimum amount of time an index has to be in an ILM step before it is considered stagnant. Defaults to
1d(1 day). -
health.ilm.max_retries_per_step -
(Dynamic) The minimum amount of times an index has retried by an ILM step before it is considered stagnant. Defaults to
100
