Thanks. Is there a similar tool for SSAS

Thanks. Is there a similar tool for SSAS 2005? We want to monitor performance, identify the most expensive MDX's etc. We currently have a trace running which wants to roll to a new file after 5K. I've tried to use the fn_trace_gettable to automate loading into a table for query but it doesn't work well. Appears like this is only intended for Database Engine traces because I'm seeing alot of garbage from the function call.
