masakari-hostmonitor

Monitor Overview

The masakari-hostmonitor provides compute node High Availability for OpenStack clouds by automatically detecting compute nodes failure via pacemaker & corosync.

How does it work?

  • Pacemaker or pacemaker-remote is required to install into compute nodes to form a pacemaker cluster.

  • The compute node’s status is depending on the heartbeat between the compute node and the cluster. Once the node lost the heartbeat, masakari-hostmonitor in other nodes will detect the faiure and send notifications to masakari-api.
