Node monitoring and administration
From the Nodes section of OpsCenter, select different views (Ring or List) of the nodes that comprise a DataStax Enterprise cluster and perform node management operations. View the status of agents, install and upgrade agents, and troubleshoot any agent issues in the Agents view.
The Nodes page for each cluster contains summary panels for Health, Data Size, and available services for DSE clusters. Click the cog icon for quick access to the Repair, NodeSync, Backup, Performance, or Best Practice Service. Click Hide or Show to toggle the view of the status panels.
The number of triggered alerts are shown for both the cluster and instance levels: at the cluster level next to the Nodes label, and also for the entire OpsCenter instance next to Alerts in the main menu bar.
