www.klgroup.com, I don't think they have a linux version (?)
or OptimizeIt ($449 ...). You are supposed to be able to use it with
Apache JServ (not sure why they mention it specifically, but they do:
http://www.optimizeit.com/opr120799.html
so it's not completely off-topic :) They do have a linux version and it is
working fine on my machine at work (so far just the demo).
Also, there is always the do-it-yourself method. If your vm supports JVMPI
(such as jdk1.2.2_rc3 from blackdown) you only need to write a module to
interface with this. A GPL'ed version by 2 people from Sun can be found on
http://www.garyshouse.freeserve.co.uk/jProf/jProf.html
I couldn't find the source there anymore (maybe it's all in the .zip
file). It only mentions NT and Solaris, but the Solaris version can be
compiled under linux as well (I think you only had to remove the -R from
the makefile, fix some includes and maybe something more). If you want my
modified version just ask.
With 1.2 there is also hprof which is another example on how to use JVMPI
to do profiling.
I would want a profiler similar to that (just a simple text-dump), but I
want to be able to tell it when to start/stop collecting data and what to
collect. It shouldn't be impossible to create a useful tool ...
