Take a look at the last pid values and the time of each top snapshot: last pid: 92665; load averages: 2.40, 2.68, 4.75up 5+02:45:23 20:29:07 last pid: 99336; load averages: 1.47, 2.05, 3.66up 5+02:52:06 20:35:50 So, in 7 minutes your system has launched 6671 processes, and in your first top snapshot I see sh and snmpget processses. The reason you don't see any processes in top consuming CPU is that they are being created and then exit before top can print them. If you turn process accounting on (add accounting_enable=YES to /etc/rc.conf, then run /etc/rc.d.d/accounting start), you can run the lastcomm command to see a log of every process that has exited and its CPU usage. It won't really tell you any more than you are running Cacti and monitoring a lot of devices :) -- Dan Nelson dnel...@allantgroup.com ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
