threshold values for CPU Load Check
Posted: Thu Dec 20, 2018 8:08 am
Team,
I am trying to set warn and critical CPU Load threshold values for Nagios server (Which is currently polling some 1000 services at polling interval of 1 minute) using check_load nagios plugin.
Threshold Calculation Formula:
y = c * p /100
where y --> Nagios Value, c --> Number of CPU cores, p --> Percent Threshold limit expected
My Nagios server has 8 processors with each having 8 CPU cores and hyper threading is enabled.
For WARN_Load = 0.8,0.8,0.75 and CRIT_Load = 0.9, 0.9, 0.85 I calculated Load limits as -w 51.2, 51.2, 48 -c 57.6, 57.6 54.4
But still Load gets Critical!
Any thoughts on how to handle would be highly appreciated!
