Navigator Luna KMS Proxy Health Tests

Navigator Luna KMS Proxy Audit Pipeline Test

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

Navigator Luna KMS Proxy Process Status

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

Navigator Luna KMS Proxy Unexpected Exits

This Navigator Luna KMS Proxy health test checks that the Navigator Luna KMS Proxy has not recently exited unexpectedly. The test returns "Bad" health if the number of unexpected exits exceeds a critical threshold. For example, if this test is configured with a critical threshold of 1, this test returns "Good" health if there have been no unexpected exits recently. If 1 or more unexpected exits occured recently, this test returns "Bad" health. The test also indicates whether any of the exits were caused by an OutOfMemory error if the Cloudera Manager Kill When Out of Memory monitoring setting is enabled. This test can be configured using the Unexpected Exits Thresholds and Unexpected Exits Monitoring Period Navigator Luna KMS Proxy monitoring settings.
