FYI, the wildcard character in the SQL filter when editing the top xx component resource is %, not * as the documentation at the help link would lead you to believe.
Resource: Top XX Components by Statistic Data (SAM). Click Edit, in the filter field, enter Monitor.Name Like '*something' as the documentation suggest and you get NOTHING! However, enter Monitor.Name Like '%something' and you get results.
This is were the link sends you: SQL Filter Syntax Examples
Just FYI in case someone comes looking for the same thing I was.
Also, FWIW I figured that out by going to the SAM Summary page, clicking Edit on the All Applications resource and seeing the SWQL filter examples listed there, one of which is Nodes.Caption like 'Exchange%'
