Hello Nagios Community and Team,

I am sure this has been posted before, but I promised my supervisor I'd try to get the most up to date information!

With the upcoming changes to WMI, we're met with a predicament that I am sure some other folks have run into; we currently perform WMI checks with check_wmi_plus.pl.

I am hoping to get some general recommendations or possibly some experiences that other folks have with regards to this predicament.

Our current thoughts for remediation are one of the three options:

1) Utilize Win_RM to perform the checks as discussed in the Nagios Webinar here: https://www.nagios.com/events/webinars/ ... onitoring/.

We have determined that using OpenSSH will not be an option based off of the statements in this webinar. We also did not have access to the beta to test out the changes, so hoping to get some experiences on how that went from beta testers.

2) Utilize the changes to check_wmi_plus.pl found here: https://edcint.co.nz/checkwmiplus/

It appears that the developer of check_wmi_plus.pl has modified check_wmi_plus.pl in a way to utilize a wmic_server to perform the checks vs the old method of check_wmi_plus.pl calling the wmic tool directly.

3) Deploying agents (NSClient++/NCPA) to servers. This would be the heaviest lift for us as we currently monitor around 550 servers using WMI, leaving us with 550 deployments and subsequent configuration changes in Nagios.

Any help, opinions, suggestions, or experiences regarding this is greatly appreciated!

Thank you!
Paul

I am very interested in how this is going to be resolved. We have hundreds of Windows servers and we want to start building our Windows 2022 servers asap. But if MS changes the way it works, will check_wmi stop working?

Hello kbauma01,

That is correct, the changes that Microsoft will be making on March 14, 2023 will break check_wmi_plus.pl.
Microsoft's KB article here talks about the changes that they will be making: https://support.microsoft.com/en-us/top ... ed901c769c

Best,

How this situation is ultimately settled has my full attention. Our company uses hundreds of Windows servers and needs to begin constructing Windows 2022 servers immediately. But what happens to check_wmi if Microsoft decides to change how it operates?
