Using Trace Counters to Troubleshoot NerveCenter
A useful tool for troubleshooting NerveCenter is it trace counters feature. Trace counters enable NerveCenter to keep track of its own activities, such as the number of SNMP traps that have been received, polls requested, Informs sent, and quite a few other operations. The cumulative count for an operation reflects total activity for either of the following durations:
- For as long as the NerveCenter Server has been running; or
- If you have reset a counter, since the reset was performed.
If you are having difficulties with NerveCenter, a Open Technical Support representative may provide further instructions for using the Trace counters, including enabling trace logging.
NerveCenter's trace logging feature should only be used as directed by Technical Support. Trace logging quickly consumes large blocks of memory and could impact Server performance.
Even though the data presented by the trace counters are read-only, you can reset a counter. The following table explains what procedures are related to the trace counters:
Procedures Related to Trace Counters1
|
Task
|
Procedure
