Authentication Server Health Tests

Authentication Server Audit Pipeline Test

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

Short Name: Audit Pipeline Test

Property Name	Description	Template Name	Default Value	Unit
Monitoring Period For Audit Failures	The period to review when checking if audits are blocked and not getting processed.	mgmt_navigator_failure_window	20	MINUTES
Navigator Audit Failure Thresholds	The health test thresholds for failures encountered when monitoring audits within a recent period specified by the mgmt_navigator_failure_window configuration for the role. The value that can be specified for this threshold is the number of bytes of audits data that is left to be sent to audit server.	mgmt_navigator_failure_thresholds	critical:any, warning:never	BYTES
Navigator Audit Pipeline Health Check	Enable test of audit events processing pipeline. This will test if audit events are not getting processed by Audit Server for a role that generates audit.	mgmt_navigator_status_check_enabled	true	no unit

Authentication Server File Descriptors

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

Short Name: File Descriptors

Property Name	Description	Template Name	Default Value	Unit
File Descriptor Monitoring Thresholds	The health test thresholds of the number of file descriptors used. Specified as a percentage of file descriptor limit.	authserver_fd_thresholds	critical:70.0, warning:50.0	PERCENT

Authentication Server Heap Dump Directory Free Space

This Authentication Server health test checks that the filesystem containing the heap dump directory of this Authentication 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 Authentication Server monitoring settings.

Short Name: Heap Dump Directory Free Space

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

Authentication Server Host Health

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

Short Name: Host Health

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

Authentication Server Log Directory Free Space

This Authentication Server health test checks that the filesystem containing the log directory of this Authentication 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 Authentication 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

Authentication Server Process Status

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

Short Name: Process Status

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

Authentication Server Swap Memory Usage

This Authentication 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. This takes precedence over the host level threshold.	process_swap_memory_thresholds	critical:never, warning:200.0	BYTES

Authentication Server Unexpected Exits

This Authentication Server health test checks that the Authentication 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 Authentication 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
