Plugin accepts three values of overused cores for warn and crit to check load average
first param: la1
second param: la5
third param: la15
The plugin calculates the limit relative to the number of cpu cores of the server.
Plugin may work in two mode: pecentage or quantitative.
Parameters of plugin may accept integer and non-integer numbers including negatives for both modes.
To use percentage mode symbol '%' must be specified in value strings.
If at least one value has a '%' symbol, the percentage mode is used.
Default values in relative mode:
warn: 15\%,0\%,-7\%
crit: 100\%,70\%,50\%
Allowed formats:
--warn 1
--crit 1\%,-2\%
For any unspecified params, corresponding default will be used
