check_load question

[Jan Scholten]

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
