Cluster Level Monitoring
Cluster level montoring could be the most commonly used Dashboards because cluster is the basic business unit. so the most complete and comprehensive information is aggregated at the cluster level.
Most monitoring charts are generalizations and up-rolls of instance-level monitoring, i.e., they change from showing details within a single instance to showing information about each instance within the cluster and metrics aggregated at the cluster and service levels.
Cluster Overview
Cluster overview at Cluster level has a few more things compared to instance level.
- Timeline and leadership, when a Failover or Switchover occurs in the database, the timeline is stepped and the leadership changes.
- Cluster Topology, the cluster topology shows the replication topology in the cluster and the replication method used (synchronous/asynchronous).
- Cluster Load, which includes the load of the entire cluster in real time, 1 minute, 5 minutes, 15 minutes. and Load1 of each node in the cluster
- Cluster alarms and events.
