Thanks all for your responses to my question last month about P6Spy and JDBC profiling. It appears that quite a few of you, like me, just fix P6Spy locally, chuck it into your system (in production as well as dev) and just more or less forget about it except for the logs it produces. Otherwise, there seems to be a smattering of other technologies used, commercial and non-commercial. Some of you use the JDBC spying equivalent capability that comes with the driver, some of you use a measuring framework such as JaMon that has JDBC monitoring capabilities built in. No one convinced me there was a killer choice out there that I should be leaping to use (I'm still open minded if anyone wants to try to convince me).

how to eliminate manual problem reproduction and accelerate root-cause diagnostics

I didn't really get an answer to why the P6spy project seems to be in permanent stasis, given the number of people using it. But I guess that's the nature of the tool, it's simple enough to easily understand and fix, whereas without someone actively managing the project who is going to manage the fixes, the releases, and so on, people don't feel like taking over. And in case you are wondering why I don't do that myself, sadly I don't have the time, or I would.

Now on with this month's newsletter. We have our usual lists of Java performance tools, news, and articles. Javva The Hutt is back from holiday to tell us about his recent interview with Weevil, at fasterj we have a new cartoon Just-in-time compilation; and, of course, we have extracted tips from all of this month's referenced articles.
