Estimating PIX CPU load

Unanswered Question

Hi all.


My Customer has a Pix 520 running PIX Version 5.2(9) and cannot upgrade the software because a Token Ring interface on the firewall is needed.

Given that the "show cpu usage" command is not available on that software release, how can I calculate an estimate of the cpu load?


I have sampled the output of "show processes" once a minute (about 60000 milliseconds) for several minutes and I have observed that the 557poll process has a Runtime of about 46000 milliseconds per minute. Does this mean that the cpu load produced by that process is 46/60= 76.6%? Of course I hope not!


Any hint is appreciated


Thank you
