But then i check it like this:

Code: Select all

./check_snmp_load.pl -H 10.3.1.1 -C public -w 80 -c 90
I get result that says average load 0% all the time.
2 CPU, average load 0.0% < 80% : OK
When i configured this plugin to work, in the WebGUI i get critical status and status information
(Service check did not exit properly)
Help anyone.

Re: Problems with check_snmp_load plugin

I managed to change the plugin return status to OK in WebGui. But the result is
2 CPU, average load 0.0% < 85% : OK average
