IIS v10 mgmt pack server 2016,1709+ discovering items that do not exist RRS feed

  • Question

  • In attempting to get a handle on the monitoring and alerting of IIS and app pools in my environment, I recently imported v10.0.9.1 of IISv10. Already had IIS7, v6.0.7600.0 and iis8, v7.0.10247.0 and Library is at 10.0.9.1

    After the initial discoveries a few days ago, I now have an over whelming number (1521) app pools with customers asking what the heck is going on!!!

    Can someone please provide some insight if they have experienced this issue and info on how I can fix this other than doing an overrides for each and everyone of these! This is totally ridiculous!

    Environment: SCOM 2012R2 UR12

    Thanks in advance for your time and assistance!

  • Morning, It was discovering app pools/IIS where there were not any. I ran a powershell script to look for servers where the IISAdmin andW3SVC service did not exist, created a group to put them in and did an override for IIS7, IIs 8 and IIS 10 Server Role Discovery so that these will no longer be picked up. It also has the advantage of being used for servers where those items do exist but the service owner does not want to be alerted on them or is using another product to monitor the app pools.

    Thanks,

  • Hi,

    What exactly is your question? Too many app pools were discovered in SCOM and you want to un-discover them?

    Cheers

  • Morning and thank you for your response. Yes, it has erroneously discovered web services and app pools on servers where there are none.

    Yes please, I am in need of a way to prevent these from being discovered/rediscovered and remove them from being displayed.

    Thanks,

    Tony

  • Are you sure app pools were discovered "where there are none"? Given how discoveries work, that would really surprise me...

    edit : the iis v10 probe is based on a native module though, so it's more complicated to find exactly what it's doing, it would require unpacking the dll which I can't do right now.

  • Surprises me as well.

    Are the pools being discovered with any specific name like "default app pool" or something?

    Cheers

  • I'm not crazy, happens to me as well!!! :)  The MP seems to discover a phantom IIS and Default Web Site / App Pool...  Here's a demonstration.  SCOM alert and Windows Features installed...  Guess I'll have to recreate the discovery.
