In a few occasions we were able to spot memory leaks and inappropriate JVM memory settings as well as thread leaks by looking at the long time graphs, but not much more.
(Most of) Java folks are big on code reuse, which for them apparently means to just plug in appropriate libs, connect the black boxes with some glue code and never bother to figure out what is really going on inside, not even when things hit the fan. In such circumstances it is very difficult to achieve the levels of cooperation to actually make sense of the JVM metrics. I still grin when I remember the blank stares Java folks are giving me when I start asking questions about inner workings of the JVM, this appears to be a major heresy :) > Also if anyone knows of any appropriate primers that might get me up to > scratch on this from a sysadmins perspective I'd appreciate it.
