I think this question came up fairly recently, so you might want to search the IBM-MAIN archives. IBM Tivoli Composite Application Management (ITCAM) comes to mind as one such tool. Here's the Web link: http://www.ibm.com/software/tivoli/products/composite-application-mgr-rtt/ IBM just acquired Micromuse, a company also very involved in this area. And there are certainly other tools and products. On z/OS at least some of the base technology to feed end-to-end performance analysis you get for "free" (WLM, SMF, RMF...), but the trick is to correlate all that information into something meaningful -- including correlation with information outside z/OS (e.g. network and end-user device performance). I remember working with one customer that couldn't figure out why "the mainframe is slow" until they determined that somebody had a PC with less (stolen?) RAM, and Internet Explorer was swapping, causing Web pages to display very slowly. If they had an end-to-end tool the troubleshooting would have been easy and rapid. I know that episode sounds silly, but I'm sure many people here have similar experiences. I think part of the reason mainframe folks get called is because they're generally competent. :-) - - - - - Timothy F. Sipples Consulting Enterprise Software Architect, z9/zSeries IBM Japan, Ltd.
