try the command "top" on your Servers the actual Load avarage i in the
first line (on the right side)
Be happy if your Server has a load of 0.
You can define different warning/critical values for the actual, 5 min,
and 15 min load avarage.
so a check_load -w 10,8,5 -c 15,10,8
means:
warn if current load is higher than 10
or 5 Min load avarage is higer than 8
or 15 min Load avarage is higher than 5
same for critical
