      Monitoring Metrics

      Instance summary

      Metric Description Unit Dimension
      MemUsed Memory capacity actually used, including data and cache MB instanceid
      CpuUtil Average CPU utilization % instanceid
      MemUtil Ratio of the memory actually used to the total memory requested % instanceid
      Keys Total number of keys stored in the instance (first-level keys) - instanceid
      Expired Number of keys that expired in the time window, which corresponds to the expired_keys output by the info command - instanceid

      CmdErr Number of command execution errors, such as when a command does not exist or a parameter is incorrect - instanceid
      CmdHitsRatio Key hits/(key hits + key misses). This metric can reflect the situation of cache miss % instanceid
      CpuMaxUtil Maximum CPU utilization of nodes (shards or replicas) in the instance % instanceid
      MemMaxUtil Maximum memory utilization of nodes (shards or replicas) in the instance % instanceid
