To see the list of full options you can run:
$ ./bin/check-load.rb --help Usage: ./bin/check-load.rb (options) -c, --crit L1,L5,L15 Load CRITICAL threshold, 1/5/15 min average -w, --warn L1,L5,L15 Load WARNING threshold, 1/5/15 min average
This check should work on linux systems and many other unix systems. The check takes the loadavg and divide by the number of cores. You can use
-w/-c with a comma separated value for 1/5/15 minute thresholds.
