I’m not completely sure that I’ve ever needed to disable all discoveries in an MP…(some of them yes)…In most cases if I want none of the discoveries then I may as well just delete the MP.

So last night I was on a call with a customer and during that conversation the question was asked, ‘Can we disable all rules in a management pack using PowerShell or the Console?’.

Well yes you can, although it’s a pretty drastic measure to disable everything…That said the task itself is pretty easy. Well, actually it’s pretty long winded if you use the console but yes it can be done…1 by 1, by 1, by 1… sigh. Be prepared to stay awhile if you use this method.

Today I was asked for a list of all Servers that we have configured in SCOM, plus the IP Addresses that it’s configured with. This is pretty easy to do and here’s how.

One of the hotly anticipated features of SCOM 2016 is the new Maintenance Mode updates, or more specifically…Maintenance Schedules as they are known…the ability schedule a maintenance in the future! Prior to SCOM 2016 we had to contend with doing it manually, or scripting up a solution and triggering that via a scheduled task.
