when I tried to run Service Monitoring Dashboard in OEM, one of the screen ask for the "Web Application to included in this report" so I was trying to picl the web site "EM WEbsite" (the only one target type that I have in my GRID), two questions

1. what is this EM Website for?
2. right now it show as down, do I need for it to be up? everything in my GRID seems to work ok but this guy is down and I don't know what it's for.
