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,

we have an unix system which has
load average normally about 20.
but while i am running a particular unix batch which performs heavy
operations on filesystem and database average load
reduces to 15.
how can we explain this situation?
while running that batch idle cpu time is about %60-65... (0 Replies)

TLOAD(1) User Commands TLOAD(1)NAME
tload - graphic representation of system load average
SYNOPSIS
tload [options] [tty]
DESCRIPTION
tload prints a graph of the current system load average to the specified tty (or the tty of the tload process if none is specified).
OPTIONS -s, --scale number
The scale option allows a vertical scale to be specified for the display (in characters between graph ticks); thus, a smaller value
represents a larger scale, and vice versa.
-d, --delay seconds
The delay sets the delay between graph updates in seconds.
-h, --help
Display this help text.
-V, --version
Display version information and exit.
FILES
/proc/loadavg load average information
SEE ALSO ps(1), top(1), uptime(1), w(1)BUGS
The -d delay option sets the time argument for an alarm(2); if -d 0 is specified, the alarm is set to 0, which will never send the SIGALRM
and update the display.
