Hi! Welcome to the forum!

First thing to consider, are you trying to monitor a Windows or Linux host?

Do you have an agent installed on the systems currently or are you even monitoring them at this time?

If an agent, which (NCPA or NSClient++)? Please be specific and include the exact version.

If not using an agent, what protocols are you currently using to monitor them?

Here's a quick powershell script I wrote:

Code: Select all

param (
    [string]$mode = "CPU",
    [string]$number = 10
)

$output = (Get-Process | Sort-Object $mode -desc | Select-Object -first $number | Format-Table | Out-String)

if ($output) {
    Write-Host "$output"
	exit 0
} else {
    Write-Host "UNKNOWN - Something went wrong!"
	exit 3
}

Default mode shows top 10 CPU:

Code: Select all

You can change it to use top 10 MEM (working set) if you do:

Will that work?

Posted: **Tue Nov 26, 2019 7:16 pm**

yes I'm using NSClient++ agent, this powershell lookings great but we are loking for something to check if one or more proces are consuming 'x'% of resources. is it posible? I was using NCPA with -M processes but it shows me all processes and I don't know how to filter it

Posted: **Wed Nov 27, 2019 12:32 pm**

someone?

Posted: **Wed Nov 27, 2019 3:59 pm**

This is definitely going to have to be a custom written plugin. And given the scope, and how the plugin would have to be written, it's no small endeavor. You would need to dynamically read the number of resources (of a specific type, so memory in MB, CPU in...CPU cycles?). Then find all of the logged in users. Then go through each user and find all of their processes. Then find a command that gives you the number of resources of the specific type, and add them up.

It can be done. But I don't know of any plugin that already exists to do it. It might be best to start small with this one and just figure out how to collect the amount of memory a particular user is using.
