Sometimes it is necessary to not only return a list of objects contained in a group, but also return all or specific objects nested in a group at different levels.

One thing to think about when authoring rules and monitors is performance, and Windows event monitoring is no exception.

I haven’t looked at the internals of this monitor in a long time. But recently I was working on a modified disk free space monitoring solution for a customer, and to my surprise uncovered the fact that the built-in logical disk space monitor in the Windows management packs do not utilize cookdown.
