I'm guessing that the alarm threshold coded in Nagios is set to alarm on a value without regard to number of cores. I'd have a look at the scripts and make adjustments such that the number of cores is taken into account.
I just peeked at one of our larger machines (255 cores) which is showing this load average:
Depending on the sophistication of the scheduler, it is very possible to end up with a machine that is more heavily loaded. It's also possible that the load is more evenly balanced than it appears from the Nagios alarms, but the other machines are just running under the threshold value.
Hi,
I am seeing very high kernel usage and very high load averages on my system (Although we are not loading much data to our database). Here is the output of top...does anyone know what i should be looking at?
Thanks,
