Stale Discovery Data - Argh!

Right - so you have a discovery with stale data. This could happen in a few ways, such as disabling a discovery for a certain group, wanting to 'clean' discovery data for an entire class, etc. The annoying thing is that once you have disabled the discovery, the previously discovered objects remain discovered.

Annoying, huh? Well, there is a solution. This method is by design because there are two methods of submitting discovery data (Snapshot and Incremental). We are able to remove all stale data by performing the following steps:

1) Create a Enabled=False Override for the class/group of your choice.
2) Open the Command Line and use the following:

Remove-DisabledMonitoringObject

This will remove all "disabled" discovery data.

...and you're done!
