Meet The New Nagios Core Services Platform
Built on over 25 years of monitoring experience, the Nagios Core Services Platform provides insightful monitoring dashboards, time-saving monitoring wizards, and unmatched ease of use. Use it for free indefinitely.
Monitoring Made Magically Better
- Nagios Core on Overdrive
- Powerful Monitoring Dashboards
- Time-Saving Configuration Wizards
- Open Source Powered Monitoring On Steroids
- And So Much More!
This plugin will generate an alert if
* The overall CPU usage exceeds a given threshold
* The overall CPU IO Wait exceeds a given threshold
* The CPU usage of any single CPU core exceeds a threshold
* The CPU IO Wait of any single CPU core exceeds a threshold
* The CPU steal of any single CPU core exceeds a threshold
This plugin also generates performance data suitable for PNP4Nagios, and a suitable PNP4Nagios template is supplied.
The template provides a neater presentation than the default.
Note that this plugin measures CPU usage by reading /proc/stat twice over a time interval (default is 1 second).
As such:
* It is specific to Linux, and probably won't work on other systems
* It does NOT rely on the python library psutil, and hence is backwards compatible
with older Linux systems which do have the psutil library.
New features for version 1.5
* Can alert on overall IO Wait (missing from previous versions)
* Can output the raw values from /proc/stat - see option '-a'
* Also outputs ctxt and processes (context switches and new processes) as performance data (no alerting, just for graphing)
This plugin is a fork of check_cpu.py by Kirk Hammond, and was written to cater for older Linux distributions which do
not have a the library psutil available. It also adds the feature of monitoring IO Wait explicitly.

it good, but it might require more switches to control too much info.
