Apache metrics

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

Metric Units Description
sw.metrics.healthscore Percent (%)

Health score. A health score provides real-time insight into the overall health and performance of your monitored entities. The health score is calculated based on anomalies detected for the entity, alerts triggered for the entity's metrics, and the status of the entity. The health score is displayed as a single numerical value that ranges from a Good (70-100) to Moderate (40-69) to Bad (0-39) distinction.

To view the health score for Apache Web Server entities in the Metrics Explorer, filter the sw.metrics.healthscore metric by entity_types and select apacheinstance.
