AutoOps shows different recommendations depending on how their conditions match your deployment or cluster.

High CPU on a node increases search and indexing latency and can lead to rejected requests or timeouts. It is usually a symptom of underlying pressure such as expensive queries, heavy ingest, or configuration that keeps the node saturated.

If the node stays distressed, query responses slow further and the node can disconnect from the cluster.
