Enable Health Alerts for this Role When set, Cloudera Manager will send alerts when the health of this role reaches the threshold specified by the EventServer setting eventserver_health_events_alert_threshold true enable_alerts false
Enable Configuration Change Alerts When set, Cloudera Manager will send alerts when this entity's configuration changes. false enable_config_alerts false
File Descriptor Monitoring Thresholds The health test thresholds of the number of file descriptors used. Specified as a percentage of file descriptor limit. Warning: 50.0 %, Critical: 70.0 % kudu_master_fd_thresholds false
Master Host Health Test When computing the overall Master health, consider the host's health. true kudu_master_host_health_enabled false
Master Process Health Test Enables the health test that the Master's process state is consistent with the role configuration true kudu_master_scm_health_enabled false
Process Swap Memory Thresholds The health test thresholds on the swap memory usage of the process. Warning: Any, Critical: Never process_swap_memory_thresholds false
Role Triggers The configured triggers for this role. This is a JSON-formatted list of triggers. These triggers are evaluated as part as the health system. Every trigger expression is parsed, and if the trigger condition is met, the list of actions provided in the trigger expression is executed. Each trigger has the following fields:
  • triggerName (mandatory) - The name of the trigger. This value must be unique for the specific role.
  • triggerExpression (mandatory) - A tsquery expression representing the trigger.
  • streamThreshold (optional) - The maximum number of streams that can satisfy a condition of a trigger before the condition fires. By default set to 0, and any stream returned causes the condition to fire.
  • enabled (optional) - By default set to 'true'. If set to 'false', the trigger is not evaluated.
  • expressionEditorConfig (optional) - Metadata for the trigger editor. If present, the trigger should only be edited from the Edit Trigger page; editing the trigger here can lead to inconsistencies.
For example, the following JSON formatted trigger configured for a DataNode fires if the DataNode has more than 1500 file descriptors opened:[{"triggerName": "sample-trigger", "triggerExpression": "IF (SELECT fd_open WHERE roleName=$ROLENAME and last(fd_open) > 1500) DO health:bad", "streamThreshold": 0, "enabled": "true"}]See the trigger rules documentation for more details on how to write triggers using tsquery.The JSON format is evolving and may change and, as a result, backward compatibility is not guaranteed between releases.		 [] role_triggers true
Unexpected Exits Thresholds The health test thresholds for unexpected exits encountered within a recent period specified by the unexpected_exits_window configuration for the role. Warning: Never, Critical: Any unexpected_exits_thresholds false
Unexpected Exits Monitoring Period The period to review when computing unexpected exits. 5 minute(s) unexpected_exits_window false
