Monitoring Alarms

On a cluster with an Enterprise Edition or Enterprise Database Edition license, MapR raises alarms to alert you to information about the cluster:

  • Cluster health, including disk failures
  • Volumes that are under-replicated or over quota
  • Services not running

You can see any currently raised alarms in the Alarms Views view of the MapR Control System, or using the alarm list command. For a list of all alarms, see the Alarms Reference.
