Navigator Metadata Server Host Health

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

Short Name: Host Health

Property Name Description Template Name Default Value Unit
Navigator Metadata Server Host Health Test When computing the overall Navigator Metadata Server health, consider the host's health. navigatormetaserver_host_health_enabled true no unit

Navigator Metadata Server Log Directory Free Space

This Navigator Metadata Server health test checks that the filesystem containing the log directory of this Navigator Metadata 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 Navigator Metadata Server monitoring settings.

Short Name: Log Directory Free Space

Property Name Description Template Name Default Value Unit
Log Directory Free Space Monitoring Absolute Thresholds The health test thresholds for monitoring of free space on the filesystem that contains this role's log directory. log_directory_free_space_absolute_thresholds critical:5.36870912E9, warning:1.073741824E10 BYTES
Log Directory Free Space Monitoring Percentage Thresholds The health test thresholds for monitoring of free space on the filesystem that contains this role's log directory. Specified as a percentage of the capacity on that filesystem. This setting is not used if a Log Directory Free Space Monitoring Absolute Thresholds setting is configured. log_directory_free_space_percentage_thresholds critical:never, warning:never PERCENT

Navigator Metadata Server Navigator Metadata Server Storage Dir Free Space

This is a Navigator Metadata Server health test that checks that the filesystem containing the Navigator Metadata Server Storage Dir of this Navigator Metadata Server has sufficient free space. See the Navigator Metadata Server Storage Dir description on the Navigator Metadata Server configuration page for more information on this directory type. This test can be configured using the Navigator Metadata Server Storage Dir Free Space Monitoring Absolute Thresholds and Navigator Metadata Server Storage Dir Free Space Monitoring Percentage Thresholds Navigator Metadata Server monitoring settings.

Short Name: Navigator Metadata Server Storage Dir Free Space

Property Name Description Template Name Default Value Unit
Navigator Metadata Server Storage Dir Free Space Monitoring Absolute Thresholds The health test thresholds for monitoring of free space on the filesystem that contains this role's Navigator Metadata Server Storage Dir. navigatormetaserver_data_directory_free_space_absolute_thresholds critical:5.36870912E9, warning:1.073741824E10 BYTES
Navigator Metadata Server Storage Dir Free Space Monitoring Percentage Thresholds The health test thresholds for monitoring of free space on the filesystem that contains this role's Navigator Metadata Server Storage Dir. Specified as a percentage of the capacity on that filesystem. This setting is not used if a Navigator Metadata Server Storage Dir Free Space Monitoring Absolute Thresholds setting is configured. navigatormetaserver_data_directory_free_space_percentage_thresholds critical:never, warning:never PERCENT

Navigator Metadata Server Process Status

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

Short Name: Process Status

Property Name Description Template Name Default Value Unit
Navigator Metadata Server Process Health Test Enables the health test that the Navigator Metadata Server's process state is consistent with the role configuration navigatormetaserver_scm_health_enabled true no unit

Navigator Metadata Server Swap Memory Usage

This Navigator Metadata 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

Property Name Description Template Name Default Value Unit
Process Swap Memory Thresholds The health test thresholds on the swap memory usage of the process. process_swap_memory_thresholds critical:never, warning:any BYTES

Navigator Metadata Server Unexpected Exits

This Navigator Metadata Server health test checks that the Navigator Metadata Server 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 Metadata Server monitoring settings.

Short Name: Unexpected Exits

Property Name Description Template Name Default Value Unit
Unexpected Exits Monitoring Period The period to review when computing unexpected exits. unexpected_exits_window 5 MINUTES
Unexpected Exits Thresholds The health test thresholds for unexpected exits encountered within a recent period specified by the unexpected_exits_window configuration for the role. unexpected_exits_thresholds critical:any, warning:never no unit
