RecordService Worker Health Tests

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

Short Name: Audit Pipeline Test

This RecordService Worker health test checks that the number of file descriptors used does not rise above some percentage of the RecordService Worker file descriptor limit. A failure of this health test may indicate a bug in either Hadoop or Cloudera Manager. Contact Cloudera support. This test can be configured using the File Descriptor Monitoring Thresholds RecordService Worker monitoring setting.

Short Name: File Descriptors

This RecordService Worker health test factors in the health of the host upon which the RecordService Worker is running. A failure of this test means that the host running the RecordService Worker is experiencing some problem. See that host's status page for more details.This test can be enabled or disabled using the RecordService Worker Host Health Test RecordService Worker monitoring setting.

Short Name: Host Health

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

This RecordService Worker health test checks the amount of swap memory in use by the role. A failure of this health test may indicate that your machine is overloaded. This test can be configured using the Process Swap Memory Thresholds monitoring settings.

Short Name: Swap Memory Usage

This RecordService Worker health test checks that the RecordService Worker 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 RecordService Worker monitoring settings.

Short Name: Unexpected Exits
