Subject Re: Trend Analyser Tool - what should it be able to do?
Date Thu, 22 Jan 2009 04:44:00 GMT
I think my main user story behind this tool was:

We release a critical patch onto production and we want to ensure that the
system performance is not impacted. If we could compare the pre and post
patch systems, we would know where things are.

Thanks and Regards,
