Hue Server Health Tests

This Hue Server health test checks that the number of file descriptors used does not rise above some percentage of the Hue Server 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 Hue Server monitoring setting.

Short Name: File Descriptors

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

Short Name: Host Health

This Hue Server health test checks that the filesystem containing the log directory of this Hue Server has sufficient free space. This test can be configured using the Log Directory Free Space Monitoring Absolute Thresholds and Log Directory Free Space Monitoring Percentage Thresholds Hue Server monitoring settings.

Short Name: Log Directory Free Space

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

Short Name: Process Status

This Hue Server health test checks that the Hue Server has not recently exited unexpectedly. The test returns "Bad" health if the number of unexpected exits goes above a critical threshold. For example, if this test is configured with a critical threshold of 1, this test would return "Good" health if there have been no unexpected exits recently. If there has been 1 or more unexpected exits recently, this test would return "Bad" health. This test can be configured using the Unexpected Exits Thresholds and Unexpected Exits Monitoring Period Hue Server monitoring settings.
