Top 3 processes consuming CPU

How can we get the information of Top 3 Processes consuming CPU using wmi and snmp in NagiosXI??
Can we use any plugin or shell script to get this information?

I'm not certain about snmp or vmi, but here is a powershell script:
https://exchange.nagios.org/directory/P ... 29/details
I think it will need to be slightly modified on line 33 to return top three:
Code: Select all
$cpuhog = (get-process -computername $servername | sort-object CPU -descending | select-object -first 3)
and a shell script:
https://exchange.nagios.org/directory/P ... es/details
again needing a slight modification on line 201:
Code: Select all
COMMAND=`UNIX95= ps -e -o pcpu,comm,pid | sort -n -r | grep -v "%CPU" | head -3`
and 205:
TOPFIVE="Top 3 CPU Processes(cpu%,pname,pid):" ;

Will this work as a plugin?
let's suppose, I save this script in Nagios host. Can we set some parameters using nagios GUI interface in a way that whenever we receive a Warning/Critical alert, this script will flick another alert stating the top5 processes consuming memory/ CPU.
????

Are you trying to monitor the "top 3" most CPU intensive processes on a remote machine (Windows, Linux, etc.) or on the Nagios XI server itself? Can you clarify?
With any 3rd party plugin (that is not included in XI by default), the process would be the same:
1. Test the plugin from the command line to make sure it works as expected
2.Define a command in Nagios XI
3. Add a service
4. Verify your service is working
For more information please review our official documentation on managing plugins in Nagios XI here:
