SolarWinds NPM threshold types

Thresholds allow you to specify when you want to be notified that a certain metric on a device has reached a certain level.

  • When a metric reaches the specified Critical Level threshold on a node or interface, the node or interface will be displayed as bold red in resources and reports.
  • When a metric reaches the specified Warning Level thresholds on a node, the node or interface will be highlighted in red in appropriate resources and reports.
  • Flapping Routes use different colors when the thresholds are exceeded: red for the error threshold and yellow for the warning threshold.

Cisco Buffer Misses

Many Cisco devices can report buffer misses. Monitored network devices with more buffer misses than the value set for the Critical Level display as bold red in Cisco Buffer resources. Monitored network devices with more buffer misses than the value set for the Warning Level, but fewer than the value set for the Critical Level, display as red in Cisco Buffer resources.

Interface Errors and Discards

Monitored interfaces experiencing more errors and discards than the value set for the Critical Level display as bold red in High Errors and Discards reports and resources. Monitored interfaces experiencing more errors and discards than the value set for the Warning Level, but fewer than the value set for the Critical Level, display as red in High Errors and Discards reports and resources.

Interface Percent Utilization

Monitored interfaces experiencing current percent utilization higher than the value set for the Critical Level display in High Percent Utilization reports and resources. Gauges for these devices also display as bold red. Monitored interfaces experiencing current percent utilization higher than the value set for the Warning Level, but lower than the value set for the Critical Level, display in High Percent Utilization reports and resources. Gauges for these devices also display as red.

Specify whether you want to calculate exhaustion using average daily values or peak daily values by selecting the appropriate option in Capacity Planning.

Flapping Routes

Specify thresholds for highlighting flapping routes in the Top Flapping Routes resource.

  • If a route flaps more frequently than specified in Routing Flaps Error Threshold, the current flaps number will be highlighted in red.
  • If a route flaps more frequently than specified in Routing Flaps Warning Threshold, the current flaps number will be highlighted in yellow.
