Monitoring system health by using IBM Storage Scale GUI

The IBM Storage Scale system provides background monitoring capabilities to check the health of a cluster and each node of the cluster, including all the services that are hosted on a node. You can view the system health states or corresponding events for the selected health state on the individual pages, widgets or panels of the IBM Storage Scale GUI. You can also view system health details by issuing the mmhealth command options like mmhealth cluster show, mmhealth node show, or other similar options.

The following table lists the system health monitoring options that are available in the IBM Storage Scale GUI.
