Sqoop 2 Server Health Tests

This Sqoop 2 Server health test checks that the number of file descriptors used does not rise above some percentage of the Sqoop 2 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 Sqoop 2 Server monitoring setting.

This Sqoop 2 Server health test checks that the filesystem containing the heap dump directory of this Sqoop 2 Server has sufficient free space. This test can be configured using the Heap Dump Directory Free Space Monitoring Absolute Thresholds and Heap Dump Directory Free Space Monitoring Percentage Thresholds Sqoop 2 Server monitoring settings.

Short Name: Heap Dump Directory Free Space

This Sqoop 2 Server health test factors in the health of the host upon which the Sqoop 2 Server is running. A failure of this test means that the host running the Sqoop 2 Server is experiencing some problem. See that host's status page for more details.This test can be enabled or disabled using the Sqoop 2 Server Host Health Test Sqoop 2 Server monitoring setting.

This Sqoop 2 Server health test checks that the Cloudera Manager Agent on the Sqoop 2 Server host is heart beating correctly and that the process associated with the Sqoop 2 Server role is in the state expected by Cloudera Manager. A failure of this health test may indicate a problem with the Sqoop 2 Server process, a lack of connectivity to the Cloudera Manager Agent on the Sqoop 2 Server host, or a problem with the Cloudera Manager Agent. This test can fail either because the Sqoop 2 Server has crashed or because the Sqoop 2 Server will not start or stop in a timely fashion. Check the Sqoop 2 Server logs for more details. If the test fails because of problems communicating with the Cloudera Manager Agent on the Sqoop 2 Server host, check the status of the Cloudera Manager Agent by running /etc/init.d/cloudera-scm-agent status on the Sqoop 2 Server host, or look in the Cloudera Manager Agent logs on the Sqoop 2 Server host for more details. This test can be enabled or disabled using the Sqoop 2 Server Process Health Test Sqoop 2 Server monitoring setting.

Short Name: Process Status

This Sqoop 2 Server 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 Sqoop 2 Server health test checks that the Sqoop 2 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 Sqoop 2 Server monitoring settings.
