Viewing Alarm Information

When an alarm instance is instantiated or undergoes a transition, you need to know certain things about the alarm transition that just took place:

• Which alarm was instantiated or underwent a transition? If the name of the alarm was ifLinkUpDown, you know that you received a link-down or a link-up trap.
• What node was the alarm instance monitoring? Was it monitoring a particular interface on a device?
• What state is the alarm instance now in? And what is the severity of that state? If the alarm involved is ifLinkUpDown and the current state is LinkDown (Major severity), you know that a communication link is down.
• What NerveCenter object caused the alarm instance to be instantiated or undergo a transition? If you know that the poll MediumLoad caused the instantiation or transition, you can look at the definition of that poll to determine exactly what condition is being reported.

Both the NerveCenter Web Client and the NerveCenter Client provide interfaces that present you with summary information about the current alarm instances in which you're interested. For information about bringing up these interfaces and about the information they present, see the following sections:
