Monitoring Metrics
- Table 1 describes the monitoring metrics of CSS clusters.
- Monitored object: CSS cluster
- Monitoring period (original metric): 1 minute
Accumulated value: The value is accumulated from the time when a node is started. After the node is restarted, the value is reset to zero and accumulated again.

status |
Cluster Health Status |
Health status of the monitored object |
0,1,2,3 0: The cluster is 100% available. 1: The data is complete while some replicas are missing. Exceptions may occur because the high availability is compromised. This is a warning that should prompt investigation. 2: Data is missing and the cluster fails to work. 3: The cluster status is not obtained. |
