I am using PCM+ to monitor a network with only 6 HP 2610 switches. I configured snmp fo pcm to get port usage, but I can't pull a report for the port starts for a two days or a week, i can only monitor real time. How can i achieve that? I would like to pull a report for port usage (top 5 talkers for instance) for a period of say a month, how do i do that? If PCM cannot do it please advise me on management software that does.
