A simple common bash script to compute the percentage is: #!/bin/bash One way to measure utilization in % is by computation over two successive reads of /proc/stat. This was just an example plugin to use, you can google for other plugins that fits your needs.Processor use or utilization is a measurement over time. Or you use the newest version from github: I tested the plugin and you also need to edit line 251 from my $np = Nagios::Plugin->new( I assume you are using debian/ubuntu? - you need the libmonitoring-plugin-perl package. Please does anyone have answer of that ? what should i do to get the % of CPU to define the warning and critical number The result is the number of process and not the % of CPU , I have used the check_load module with that configurationĬommand_endpoint = _endpoint I have a really issue, i have a rizing on CPU on my linux server, the problem is when using procs module he gets me the number of process but i want to know the average of CPU with % so i used the check_load module but he only gets me the load average and not the CPU average of my system
