| Cluster health | Cache utilization (deprecated) Utilization level in the cluster scope. The metric is deprecated and presented for backward compatibility only, you should use the 'Cache utilization factor' metric instead. |
CacheUtilization |
Percent | Average, Maximum, Minimum | <none> | PT1M | Yes |
| Cluster health | Cache utilization factor Percentage of utilized disk space dedicated for hot cache in the cluster. 100% means that the disk space assigned to hot data is optimally utilized. No action is needed in terms of the cache size. More than 100% means that the cluster's disk space is not large enough to accommodate the hot data, as defined by your caching policies. To ensure that sufficient space is available for all the hot data, the amount of hot data needs to be reduced or the cluster needs to be scaled out. Enabling auto scale is recommended. |

| Cluster health | FollowerLatency The follower databases synchronize changes in the leader databases. Because of the synchronization, there's a data lag of a few seconds to a few minutes in data availability.This metric measures the length of the time lag. The time lag depends on the overall size of the leader database metadata.This is a cluster level metrics: the followers catch metadata of all databases that are followed. This metric represents the latency of the process. |
