NSClient++ - Check McAfee Status

I wanted to have Nagios monitor the status of McAfee Virus-Scan on our servers. I wanted to ensure that I knew of any installations where the Agent, Virus-Scan, Engine or DATs were not at a version that they should be.

To that end I decided to write a bit of PowerShell code to use in conjunction with NSClient++ that we use for monitoring our Windows servers.
You can download the PowerShell script from GitHub here:-

Put the downloaded script into your scripts folder in your NSClient++ installation location... e.g.:-

“C:\Program Files\NSClient++\scripts”

The PowerShell script will check registry keys for McAfee based on the following parameters which need to be supplied:-


If the values of the supplied parameters do not match then a Warning or Critical level will be raised back to Nagios.

To execute from within NSClient++ the following should be in the NSClient++.ini file:-

[NRPE Handlers]
check_mcafee_status = cmd /c echo scripts\Check_McAfee_Status.ps1 -AgentVersion -VScanVersion -EngineVersion 5800.7501 -WarnDays 2 -CritDays 5; exit($lastexitcode) | powershell.exe -command –

The bold numbers above should be changed to match your requirements.

On the check_nrpe command include the -t 60, since it can take longer than the standard 10 seconds to run.

I have tested this with the following x86 & x64 versions of NSClient++ version
NSClient++ version on the below Operating Systems.
