Dashboard for BO server performance

Hi Experts,

I need to create a dashboard which will exhibit the BO server performance.

Dashboard Designer 4.1 SP4 Patch1 will be used for this.

I am currently exploring  both bex as well as web service options to bring in the cubes into the dashboard,

Major concern is how do I track the infocubes, The performance data is passed to the Solution Manager, I have access to the SM system.

Has anyone seen this before? Inputs will be appreciated.Kindly suggest which infocubes can be selected for this.

Thanks,

Tania
