Virtu-Al has developed a great powerCLI script that creates a daily report of your virtual infrastructure. This gives a quick and informative representation of how things are performing. You can run this as a sheduled task and get a quick look at how the day is going to be, before you get into the office. You can see his post here
P.S. The report even looks great on an iPhone
