Using Auto-Trace To Diagnose Problems - Avaya 8800 Troubleshooting Manual

Using auto-trace to diagnose problems

You can use auto-trace to automatically perform the trace function when a parameter reaches
a certain threshold.
For example, if the SF/CPU fluctuates and accessing the switch to perform a CP trace is not
possible, use auto-trace to automatically perform this function. Auto-trace monitors CPU
utilization. When the configured utilization is reached and sustained for the configured amount
of time, a CP trace is performed and saved to the PCMCIA (or external flash on the 8895 SF/
CPU).
