Redis metrics

The following Redis metrics are collected when you monitor Redis using the native Otel integration method. See the Configure Redis integration topic.

Many of the collected metrics from the Redis 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 Redis metrics in the Metrics Explorer, type Redis in the search box.
