Thanks for the replies on this. I took a look at Apache JMeter, but it appeared to me to be used to test performance, with the emphasis on test. I'm looking more for something that might help me see performance of PE during actual usage, so when users are asking why PE isn't responding as fast as they'd like, I can refer to some data that shows how many requests came in around that time, size of the files, how long the requests were taking, etc. I'm aware of the transaction list and usage report web tools, and have actually customized the transaction list to show transaction duration and file size, but the more I add to or customize it, the more I wonder if there's not already something out there that does what I want? Maybe I didn't catch all that's possible with JMeter to monitor performance?
In the absence of something like that, has anyone customized request handlers on PE to store info like how many of the sub-processes are in use when a transaction occurs, or any other customizing that helps with performance monitoring?
Someone ... I can see his face ... can't pull the name right now ... developed a screen scraping tool that analyzed and maybe logged over time an existing PE status page. Colin? I don't know if you've looked at that page and the process reporting that it does or not, but if that info "in real time" might help you, you could look down that path.
I never saw it, I just remember him talking about it.
