missing IIS net_clr appPoolCounters

[AlexDF2017]

Hi all, on a fresh installation of metricbeat 7.17.24 under Windows Server 2022, IIS metricbeat module activated, we have the following repeating errors in metricbeat logs:

2024-10-21T20:05:42.285+0200	ERROR	[application_pool]	application_pool/reader.go:106	Element not found.failed to expand counter path (query= "%v")\.NET CLR Exceptions(w3wp*)\# of Exceps Thrown

It seems that all net_clr appPoolCounters aren't available on OS, how to fix? No particular requirement is reported on metricbeat installation documentation for IIS monitoring.

Hi @AlexDF2017,

Firstly, make sure ASP.NET is installed as this might be similar to: elastic/integrations#7992

Let me know if you still encounter the error afterwards.

Hi @lucian-ioan , sorry but we had already installed the required features & roles, the same as indicated in elastic/integrations#7992. We rebooted the server after installation to be sure, but the problem is the same,

To confirm:

Thanks for confirming, I have already tried to replicate this with our existing virtual machine running IIS with no luck.

I'll try setting up a new VM from scratch and come back to you on this.
