Monitoring Metrics¶
Table 1 describes the monitoring metrics of CSS clusters.
Monitored object: Cloud service nodes of CSS clusters
Monitoring period (original metric): 1 minute
Note
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.
