This matrix defines the severities that OpenNMS uses:

Table of OpenNMS severity definitions.
  • Critical: Numerous devices are impacted by an event.

  • Major: A device is down, or in danger of going down.

  • Minor: A part of a device (service, interface, power supply, and so on) has stopped functioning.

  • Warning: An event has occurred that may require action.

  • Normal: Informational severity message; no action is required.

  • Cleared: Indicates that an alarm with a self-clearing error condition has been corrected, and service is restored.

  • Indeterminate: No severity could be associated with the event.

For more information on the severities in OpenNMS, see A word about severities in the main OpenNMS documentation.
