Performance monitoring XI - More than one sender

Hi,

I'm tryig to do some performance analysis on my PI system. I'm going through the Process integration performance check guide for Netweaver 4s.

Anyway, I'm trying to use the performance monitoring section in the RWB.

I select "detailed data aggregated", "IS: as the data source, "Process monitoring infrastructure" and "XIntegration Server/<host>". Then I chose the time interval and hit start.

I immediatly get the error "More than one Sender is selsected. Extend your selection criteria so that the sender is unique"

Is there a fix for this issue?

Thanks,

Lee
