Service Monitor Health Tests

Service Monitor Audit Pipeline Test

This Service Monitor health test checks that the Auditing for the Service Monitor role is getting processed correctly and is not blocked. A failure of this health test may indicate a problem with the audit pipeline of Service Monitor process. This test can fail either because the Cloudera Audit Server is not accepting audits, or the Cloudera Manager Agent on the Service Monitor host isn't able to send audits because of some network issue. Check the Cloudera Manager Agent logs and Cloudera Audit Server logs for more details. This test can be enabled or disabled using the Navigator Audit Pipeline Health Check Service Monitor monitoring setting.

Service Monitor Cloudera Manager Descriptor Age

This is a Service Monitor health test that checks if the Cloudera Manager descriptor has been refreshed recently. The Cloudera Manager descriptor is used to pass configuration information from the Cloudera Manager Server to the Service Monitor. If the descriptor becomes stale, Service Monitor operation may be impacted because the Service Monitor will receive information about new hosts, roles, and services, or changes to existing hosts, roles, and services. A stale descriptor usually indicates problems communicating with the Cloudera Manager Server but can also indicate performance problems or a bug. Consult the Service Monitor log and the Cloudera Manager Server log for more information. This test can be configured using the Cloudera Manager Descriptor Age Thresholds Cloudera Manager Service Monitor setting.
