:original_name: dcs-ug-0326019.html .. _dcs-ug-0326019: DCS Metrics =========== Introduction ------------ This section describes DCS metrics reported to Cloud Eye as well as their namespaces and dimensions. You can use the Cloud Eye console or call APIs to query the DCS metrics and alarms. Different types of instances are monitored on different dimensions. - Single-node: Single-node instances are monitored on the instance dimension. The monitoring is conducted on the Redis Server. - Master/standby: Master/Standby instances are monitored on the instance and Redis Server dimensions. Instance monitoring covers the master node, while Redis Server monitoring covers the master and standby nodes. - Cluster: Proxy Cluster instances are monitored on the instance, Redis Server, and proxy dimensions. Instance monitoring covers the aggregated master node data, Redis Server monitoring covers each shard in the cluster, and proxy monitoring covers each proxy in the cluster. Redis Cluster instances are monitored on the instance and Redis Server dimensions. Instance monitoring covers the aggregated master node data and Redis Server monitoring covers each shard in the cluster.
