Reports Manager Health Tests

Reports Manager Audit Pipeline Test

This Reports Manager health test checks that the Auditing for the Reports Manager role is getting processed correctly and is not blocked. A failure of this health test may indicate a problem with the audit pipeline of Reports Manager process. This test can fail either because the Cloudera Audit Server is not accepting audits, or the Cloudera Manager Agent on the Reports Manager 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 Reports Manager monitoring setting.

Reports Manager Cloudera Manager Descriptor Age

This is a Reports Manager 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 Reports Manager. If the descriptor becomes stale, Reports Manager operation may be impacted because the Reports Manager 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 Reports Manager log and the Cloudera Manager Server log for more information. This test can be configured using the Cloudera Manager Descriptor Age Thresholds Cloudera Manager Reports Manager setting.

Reports Manager Pause Duration

This Reports Manager health test checks that the Reports Manager threads are not experiencing long scheduling pauses. The test uses a pause monitoring thread in the Reports Manager that tracks scheduling delay by noting if it is run on its requested schedule. If the thread is not run on its requested schedule, the delay is noted and considered pause time. The health test checks that no more than some percentage of recent time is spent paused. A failure of this health test may indicate that the Reports Manager is not getting enough CPU resources, or that it is spending too much time doing garbage collection. Inspect the Reports Manager logs for any pause monitor output and check garbage collection metrics exposed by the Reports Manager. This test can be configured using the Pause Duration Thresholds and Pause Duration Monitoring Period Reports Manager monitoring settings.

Reports Manager Process Status

This Reports Manager health test checks that the Cloudera Manager Agent on the Reports Manager host is heart beating correctly and that the process associated with the Reports Manager role is in the state expected by Cloudera Manager. A failure of this health test may indicate a problem with the Reports Manager process, a lack of connectivity to the Cloudera Manager Agent on the Reports Manager host, or a problem with the Cloudera Manager Agent. This test can fail either because the Reports Manager has crashed or because the Reports Manager will not start or stop in a timely fashion. Check the Reports Manager logs for more details. If the test fails because of problems communicating with the Cloudera Manager Agent on the Reports Manager host, check the status of the Cloudera Manager Agent by running /etc/init.d/cloudera-scm-agent status on the Reports Manager host, or look in the Cloudera Manager Agent logs on the Reports Manager host for more details. This test can be enabled or disabled using the Reports Manager Process Health Test Reports Manager monitoring setting.
