Cloudera Manager Events

This section provides information on events supported by Cloudera Manager.

Cloudera Manager supports the following categories of events:
Category Description
ACTIVITY_EVENT Generated by the Activity Monitor; specifically, for jobs that fail, or that run slowly (as determined by comparison with duration limits). In order to monitor your workload for slow-running jobs, you must specify monitoring settings.
AUDIT_EVENT Generated by actions performed
  • In Cloudera Manager, such as creating, configuring, starting, stopping, and deleting services or roles
  • By services that are being audited by Cloudera Navigator.
HBASE Generated by HBase with the exception of log messages, which have the LOG_MESSAGE category.
HEALTH_CHECK Indicate that certain health test activities have occurred, or that health test results have met specific conditions (thresholds).

Thresholds for various health tests can be set under the Configuration tabs for HBase, HDFS, Impala, and MapReduce service instances, at both the service and role level.

LOG_MESSAGE Generated for certain types of log messages from HDFS, MapReduce, and HBase services and roles. Log events are created when a log entry matches a set of rules for identifying messages of interest. The default set of rules is based on Cloudera experience supporting Hadoop clusters. You can configure additional log event rules if necessary.
SYSTEM Generated by system events such as parcel availability.
