Network device metrics

Many of the collected metrics from network device 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 tables list some of the critical metrics collected for these entities. To see the network device metrics in the Metrics Explorer, type sw.collector in the search box.

Standard metrics

Network device metrics

Metric Units Description
sw.collector.CPULoad.AvgLoad Percent (%)

Average CPU Utilization. Average CPU utilization of a network device instance or instances. Displayed as a percentage.
sw.collector.CPULoad.AvgPercentMemoryUsed Percent (%)

Average Memory Utilization. Average memory usages of the network device as a percentage.
sw.collector.Nodes.DisplayName [name]

Display name polled from the device to be used in custom widgets for filtering, sorting, or grouping data.
sw.collector.ResponseTime.Availability Percent (%)

Availability. Availability of the network device instance of instances. Displayed as a percentage.

May be displayed as:

  • Average Availability. An average availability of network devices.
sw.collector.ResponseTime.AvgResponseTime milliseconds (ms)

Average Response Time. The average time in milliseconds it takes the network device to respond.

sw.collector.ResponseTime.PercentLoss Percent (%)

Packet Loss. The packet loss of the network device as a percentage.

May be displayed as:

  • Average Packet Loss
sw.metrics.healthscore Percent (%)

Health score, Health, Health Score History. 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 network device instance entities in the Metrics Explorer, filter the sw.metrics.healthscore metric by entity_types and select networkdevice.
