The load plugin uses single quote in the config subroutine and thus the warning and critical values are not reported properly. Reproducible: Always Steps to Reproduce: ./plugins/load config Actual Results: load.warning $LOAD_WARN load.critical $LOAD_CRIT Expected Results: load.warning 10 load.critical 120 Change single quotes to double quotes in lines 55 and 56 of plugins/load.
This was fixed by upstream in 1.3.4.
