Find why your Elasticsearch cluster isn't healthy.
Diagnoses an unhealthy Elasticsearch cluster and reports the most likely cause with operator-applied remediation.
When to use it
Use for yellow or red cluster status, unassigned shards, allocation failures, or read-only triage before deeper investigation.
Ask it to diagnose cluster health; it returns the single most likely cause and a remediation recommendation without applying changes.
Requires an Elasticsearch 8.x or 9.x cluster, self-managed or Elastic Cloud Hosted; Elastic Cloud Serverless is not supported.
Requires the elastic CLI version 0.2 or later with stack es support; direct HTTP calls and other workarounds are prohibited.
