[Mahesh786]

HI Team,

Please help us how we can set up CPU utilization alerts on Nagios application server.

Note: Currently, we have set up load average but we need CPU utilization alerts.

Hi

Please provide us some clarification.

- do you need to know how to set up alerts on the load averages you are monitoring?
- do you need to know how to set up monitoring and alerts for CPU utilization?
- is the goal to monitor cpu utilization of a Nagios XI server?
- what Operating System is being used by the server you are trying to monitor?

Thanks

Hi Venkata,

Thank you very much for your responses!

One more question for you. Are you using two Nagios servers?
One to monitor your existing IT infrastructure (let's call him server nagios_A), with another separate
Nagios server (let's call him server nagios_B) to monitor the nagios_A server?

Thanks

H,

Please find the below.

One more question for you. Are you using two Nagios servers?- No, We are using only one Nagios application server.

Currently we are monitoring load average for that server but now we are planning to remove load average and enable the CPU monitoring.

Hi

Take a look at the check_cpu_stats.sh plugin:

Code: Select all

[root@gs-cent8-23-82 libexec]# ./check_cpu_stats.sh -h

check_cpu_stats.sh Revision 1.3.1 - CPU Utilization check script for Nagios

Usage: check_cpu_utilization.sh -w <warning value in % for iowait>

                -w  Warning level for cpu iowait
                -h  Show this page

Usage: check_cpu_stats.sh
Usage: check_cpu_stats.sh --help
Usage: check_cpu_stats.sh -w <warning>


Revision 1.3.1 (c) 2007 Steve Bosek ([email protected])

This plugin will check cpu utilization (user,system,iowait,idle in %)
-w is for reporting warning levels in percent of iowait

This plugin is provided with Nagios XI. There may be other plugins you might
be interested in at https://exchange.nagios.org/

For the check_cpu_stats.sh plugin you will need to create a command that calls out that plugin.
If you need guidance in creating the command please let me know.

Thanks

Hi

Please watch the attached video file which will show you how
to create the command and apply it as a service.

You will need to rename the file from check_cpu.txt to check_cpu.mp4

Let me know if you have any questions.

Thanks
