Dashboard took a long time to Initialize (Ways of tracing performance)

Hi BI gurus,

Alot of people have complaint about the Dashboard issues and mainly is about the design.

but what we want to know is how to trace the logs etc?

For example, The dashboard performance issue is intermittent, sometime it took a long time to initialize, and something it is working fine.

From BW side, I guess we can check SM21/ST22 for runtime/system log, and also is there any scheduled process chain/job that affecting this.

But is there any other way to check it apart from these?

E.g.: What should we trace in BOBJ side?

Is there anything in the CMC that we can use?

Any suggestion is greatly appreciated.

Thanks in advance,

Vince
