SCOM is a great product, but sometimes I would have liked that they spent a bit more time on implementing the silverlight dashboards, especially the performance one.
The reason? The usage of the hardcoded GUIDs to populate the performance counters.
Let’s back up a bit, before going on, and talk a bit about the usage scenario. Creating these dashboards using the GUI is fine, though if you need to to create a lot of the same type of dashboards, just with different targets. The GUI route can become a big timesink. Also one usually want to keep these types of dashboards in an unsealed management pack so one can do adjustments as necessary on the fly without having to go the way through Visual Studio to seal the MP anew each time a change is needed. VS still has some complexity tied to it and not everybody wants to invest time into learning this tool.
