Cluster state queue depth
Dimensions:None
Available on:OpenTelemetryOpenTelemetry (1)

Summary

Indicates the number of pending cluster state updates waiting to be processed. The cluster state is the master node's authoritative view of the cluster topology, shard allocation, and index metadata. A growing queue suggests the master node is overwhelmed, which can delay shard allocation, index creation, and recovery operations, potentially leading to cluster instability.

Cluster State Update Delayswarning

Slow cluster state updates cause delays in shard allocation, index creation, and mapping updates. Large cluster state size or master node resource constraints are common causes.
