Severity Attributes and Network Management Platforms

The severity attributes Level and Platform Name are used to help define how NerveCenter interacts with a network management platform.

Level

Each NerveCenter severity must have a unique severity level, which is represented by an integer. You associate severities that have low severity levels with alarm states representing benign conditions, and severities that have high levels with states representing serious conditions.

Now, here's how severity levels affect NerveCenter's interaction with a network management platform. When NerveCenter is set up, an administrator can define an "Inform Configuration." This configuration indicates where NerveCenter should send messages when it performs Inform alarm actions. The configuration also specifies a "Minimum Severity." If the administrator sets the Minimum Severity to 4, only transitions to alarm states with severity levels of 4 or more can cause Inform messages to be sent to a platform.

Platform Name

You can associate with each NerveCenter severity the name of a severity defined by your network management platform. For example, the predefined severity Saturated has associated with it the platform name Normal. Given this situation, if NerveCenter sends to the platform an Inform message whose variable bindings indicate that the destination alarm state in NerveCenter had a severity of Saturated, the platform will interpret this as an event of Normal severity. That is, the event will show up in the platform's event browser as an event of Normal severity, and if the map icon representing the node whose interface was saturated is (color), that icon will remain (color).
