You should be running some kind of performance metrics gathering. I would recommend "Munin" for long term monitoring. The only real issue with it is that it has a 5 minute window hard-coded so you cannot catch anything finer grain than that. But sounds like yours is much more than a short, spurious issue. If you want finer grain, use sadc and ksar. The 2 below is collecting at 2 second intervals which is pretty tight. /usr/lib/sa/sadc -d -I -F 2 /var/log/foo/bar or on a 64 bit box /usr/lib64/sa/sadc -d -I -F 2 /var/log/foo/bar It will log system stats at 2 second intervals, until you control-C it. Then you can view the file in kSar. go to "File" then "New Window" from the new window go to "Data", "Local Command" enter the command sar -A -f /var/log/foo/bar That's it! Now you will have some pretty graphs to look at! -- “Don't eat anything you've ever seen advertised on TV” - Michael Pollan, author of "In Defense of Food" _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
