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 Monitor monitoring setting.

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