Elasticsearch metrics

Many of the collected metrics from the Elasticsearch integration are displayed as widgets in SolarWinds Observability custom and pre-built dashboards; additional metrics may be collected and available in the Metrics Explorer.

This topic lists some of the critical metrics collected for the integration. To see the Elasticsearch metrics in the Metrics Explorer, type Elasticsearch in the search box.
