SCOM diagram view rendering warning

The requested view will contain at least x objects and may require substantial time to render.

For anyone that uses SCOM regularly, the warning prompt that pops up when entering the diagram view can become quite frustrating. The default threshold for this prompt is 50 objects.

Thankfully, it’s fairly easily disabled. Just create a key in the registry:

HKEY_CURRENT_USER\Software\Microsoft\Microsoft Operations Manager\3.0\Console\DiagramViewParameters

and a DWORD value called MaxNodesThreshold with a significantly higher value.
