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

Lily HBase Indexer Host Health
This Lily HBase Indexer health test factors in the health of the host upon which the Lily HBase Indexer is running. A failure of this test means that the host running the Lily HBase Indexer is experiencing some problem. See that host's status page for more details.This test can be enabled or disabled using the Lily HBase Indexer Host Health Test Lily HBase Indexer monitoring setting.
Short Name: Host Health
| Property Name | Description | Template Name | Default Value | Unit |
|---|---|---|---|---|
| Lily HBase Indexer Host Health Test | When computing the overall Lily HBase Indexer health, consider the host's health. | hbase_indexer_host_health_enabled | true | no unit |
Lily HBase Indexer Log Directory Free Space
This Lily HBase Indexer health test checks that the filesystem containing the log directory of this Lily HBase Indexer 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 Lily HBase Indexer 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 |
Lily HBase Indexer Process Status
This Lily HBase Indexer health test checks that the Cloudera Manager Agent on the Lily HBase Indexer host is heart beating correctly and that the process associated with the Lily HBase Indexer role is in the state expected by Cloudera Manager. A failure of this health test may indicate a problem with the Lily HBase Indexer process, a lack of connectivity to the Cloudera Manager Agent on the Lily HBase Indexer host, or a problem with the Cloudera Manager Agent. This test can fail either because the Lily HBase Indexer has crashed or because the Lily HBase Indexer will not start or stop in a timely fashion. Check the Lily HBase Indexer logs for more details. If the test fails because of problems communicating with the Cloudera Manager Agent on the Lily HBase Indexer host, check the status of the Cloudera Manager Agent by running /etc/init.d/cloudera-scm-agent status on the Lily HBase Indexer host, or look in the Cloudera Manager Agent logs on the Lily HBase Indexer host for more details. This test can be enabled or disabled using the Lily HBase Indexer Process Health Test Lily HBase Indexer monitoring setting.
Short Name: Process Status
| Property Name | Description | Template Name | Default Value | Unit |
|---|---|---|---|---|
| Lily HBase Indexer Process Health Test | Enables the health test that the Lily HBase Indexer's process state is consistent with the role configuration | hbase_indexer_scm_health_enabled | true | no unit |
Lily HBase Indexer Swap Memory Usage
This Lily HBase Indexer 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 |
Lily HBase Indexer Unexpected Exits
This Lily HBase Indexer health test checks that the Lily HBase Indexer 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 Lily HBase Indexer 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 |
