Cloudera Manager Events
This section provides information on events supported by Cloudera Manager.
An event is a record that something of interest has occurred – a service's health has changed state, a log message (of the appropriate severity) has been logged, and so on. Many events are enabled and configured by default.
|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 Activity Duration Rules.|
|AUDIT_EVENT||Generated by actions performed
|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. See Configuring Health Monitoring for more information.
|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.|
