Monitoring Activities

Cloudera Manager's activity monitoring capability monitors the Hive, Oozie, and streaming jobs, Impala queries, and YARN applications running or that have run on your cluster.

When the individual jobs are part of larger workflows (using Oozie, or Hive), these jobs are aggregated into MapReduce jobs that can be monitored as a whole, as well as by the component jobs.

If you are running multiple clusters, there will be a separate link in the Clusters tab for each cluster's MapReduce activities, Impala queries, and YARN applications.

The following sections describe how to view and monitor activities that run on your cluster.
