I’ve been using SCOM 2007 R2 for a few months now, and I’m liking it. It’s a good system, and thorough. You definitely have to tune it to weed out the alerts that are false or unneeded, but after that, you really get a good insight into what’s going on with your environment. It can monitor just about any type of server, application, or network hardware. But now, thanks to the talented people over at Coretech, there is a management pack that you can use to monitor how much coffee you have left. All you need a network-connected camera, and you’re good to go. See a full demo here.
