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

- Default Value
- true
- Unit(s)
- no unit
SRM Service File Descriptors
This SRM Service health test checks that the number of file descriptors used does not rise above some percentage of the SRM Service 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 SRM Service monitoring setting.
Short Name: File Descriptors
File Descriptor Monitoring Thresholds
- Description
- The health test thresholds of the number of file descriptors used. Specified as a percentage of file descriptor limit.
- Template Name
- streams_replication_manager_service_fd_thresholds
- Default Value
- critical:70.0, warning:50.0
- Unit(s)
- PERCENT
SRM Service Host Health
This SRM Service health test factors in the health of the host upon which the SRM Service is running. A failure of this test means that the host running the SRM Service is experiencing some problem. See that host's status page for more details.This test can be enabled or disabled using the SRM Service Host Health Test SRM Service monitoring setting.
Short Name: Host Health
SRM Service Host Health Test
- Description
- When computing the overall SRM Service health, consider the host's health.
- Template Name
- streams_replication_manager_service_host_health_enabled
- Default Value
- true
- Unit(s)
- no unit
SRM Service Log Directory Free Space
This SRM Service health test checks that the filesystem containing the log directory of this SRM Service 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 SRM Service monitoring settings.
Short Name: Log Directory Free Space
Log Directory Free Space Monitoring Absolute Thresholds
- Description
- The health test thresholds for monitoring of free space on the filesystem that contains this role's log directory.
- Template Name
- log_directory_free_space_absolute_thresholds
- Default Value
- critical:5.36870912E9, warning:1.073741824E10
- Unit(s)
- BYTES
Log Directory Free Space Monitoring Percentage Thresholds
- Description
- 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.
- Template Name
- log_directory_free_space_percentage_thresholds
- Default Value
- critical:never, warning:never
- Unit(s)
- PERCENT
SRM Service Process Status
This SRM Service health test checks that the Cloudera Manager Agent on the SRM Service host is heart beating correctly and that the process associated with the SRM Service role is in the state expected by Cloudera Manager. A failure of this health test may indicate a problem with the SRM Service process, a lack of connectivity to the Cloudera Manager Agent on the SRM Service host, or a problem with the Cloudera Manager Agent. This test can fail either because the SRM Service has crashed or because the SRM Service will not start or stop in a timely fashion. Check the SRM Service logs for more details. If the test fails because of problems communicating with the Cloudera Manager Agent on the SRM Service host, check the status of the Cloudera Manager Agent by running /etc/init.d/cloudera-scm-agent status on the SRM Service host, or look in the Cloudera Manager Agent logs on the SRM Service host for more details. This test can be enabled or disabled using the SRM Service Process Health Test SRM Service monitoring setting.
Short Name: Process Status
SRM Service Process Health Test
- Description
- Enables the health test that the SRM Service's process state is consistent with the role configuration
- Template Name
- streams_replication_manager_service_scm_health_enabled
- Default Value
- true
- Unit(s)
- no unit
SRM Service Swap Memory Usage
This SRM Service 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
Process Swap Memory Thresholds
- Description
- The health test thresholds on the swap memory usage of the process. This takes precedence over the host level threshold.
- Template Name
- process_swap_memory_thresholds
- Default Value
- critical:never, warning:200.0
- Unit(s)
- BYTES
SRM Service Unexpected Exits
This SRM Service health test checks that the SRM Service 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 SRM Service monitoring settings.
Short Name: Unexpected Exits
Unexpected Exits Monitoring Period
- Description
- The period to review when computing unexpected exits.
- Template Name
- unexpected_exits_window
- Default Value
- 5
- Unit(s)
- MINUTES
Unexpected Exits Thresholds
- Description
- The health test thresholds for unexpected exits encountered within a recent period specified by the unexpected_exits_window configuration for the role.
- Template Name
- unexpected_exits_thresholds
- Default Value
- critical:any, warning:never
- Unit(s)
