NGINX metrics

Many of the collected metrics from NGINX entities are displayed as widgets in SolarWinds Observability explorers; additional metrics may be collected and available in the Metrics Explorer. You can also create an alert for when an entity's metric value moves out of a specific range. See Entities in SolarWinds Observability for information about entity types in SolarWinds Observability.

The following table lists some of the metrics collected for these entities. To see the NGINX metrics in the Metrics Explorer, type nginx. in the search box.
