Chapter 1. Events
The recorded events are stored in the local database on each node. The user can get a list of recorded
events by using the mmhealth node eventlog command. Users can use the mmhealth node show
or mmhealth cluster show commands to display the active events in the node and cluster
respectively.
The recorded events can also be displayed through the GUI.
