Health Check

Mission Control integrates with Opensearch and Elasticsearch to monitor your search infrastructure.

---

Health Check

Use cases:

• Execute search queries against Opensearch/Elasticsearch indices and validate results
• Monitor cluster health and index availability
• Alert when expected documents are missing or counts change unexpectedly
• Validate log ingestion pipelines are working correctly
• Check that critical indices contain recent data

Opensearch Example

Run queries against Opensearch or Elasticsearch and validate the results.
