Even better than NetBeans, HProf comes with the JVM in 1.5 and 1.6…

Bingo! NetBeans’ profiler is very nice, thank you, and WAY easier to get started with than Eclipse, but its a GUI and you run it interactivly- good for some things, not for automated performance testing, which is what I’m trying to set up. Well, turns out HProf (Heap Profile) is a tool built into the Java Virtual Machine and available as a launch-time option whenever you run a Java program. The example on Sun’s web page profiles “javac”- pretty confident there. So I tried it on Mac OS-X and Win XP and it works just fine on both. You get percentages, not absolute times, but it gives you the total time and you can multiply out the absolute time if that’s what you really want. I must say I’m enjoying this again. Trying to get JMeter and TPTP running under Mac OS wasn’t any actual fun, since they didn’t work. In fact, having put TPTP into Ecipse, I can’t use Eclipse anymore… that’s a useful definition of software that’s not quite ready for prime time- it installs successfully, then tells you it doesn’t support your platform when you try to run with it, and it prevents your IDE from working until you figure out how to remove it. Joke’s on me, eh?

Anyone have expereince running NetBeans’ Profiler from command line?

Just found the following about running the NetBeans Profiler with Eclipse…  not command line but headed that way, maybe…


I left the following comment for Mario and I wouldn’t mind answere from anyone who reads this plea anywhere!
I’m trying to find a platform neutral profiling tool for Java- I need to support *nux, Windows and Mac OSX (yeah, BSD, but…) and I need to run from a command line so I can automate it. The Java library I’m testing is a thin client that talks TCP/IP to a server, all I care about is the client library performance, but I care on all three major platforms.

I tried to get JMeter going and realized it wasn’t aimed at what I was doing. I installed TPTP and was really hoping it would do the job but then discovered it has NO agent for Mac OSX and hasn’t for years. Phoey!  So I got NetBeans, imported my code (trivial, why can’t Eclipse be this easy?) and happily profiled on my Mac. Good so far.

Does anyone have experience running the NetBeans Profiler from Solaris, Linux, Mac OSX and/or Windows command lines?

Other all-platform Java profilers?

Many thanks for any help!!!
