No Heartbeat Alarm

Logged As



Node is not undergoing maintenance, and no heartbeat detected for over 5 minutes.


Check the status of the node manually.

Configurable at cluster level. See Configuring the Alarm Threshold Using the CLI for more information.
This alarm is raised when a node is down for more than 5 minutes. By default, this alarm is not raised if an edge node is down. To raise an alarm for edge nodes as well, set the CLDB parameter cldb.ignore.posix.only.hb.alarm to 0 using the command:
/opt/mapr/bin/maprcli config save -values '{cldb.ignore.posix.only.hb.alarm:"0"}'
