[jboss-dev-forums] [Design of JBoss Profiler] - JBoss Profiler 2 in JBoss AS 4.2.2 - Does not gather any sta

[justinwalsh]

Hi, 

I'm running JBoss profiler version 2 in JBoss 4.2.2.  I have followed the instructions in the README.txt verbatim, but cannot get it to 'log' any method calls.

My setup is as follows:
- Windows XP machine
- Compiled JBoss Profiler version 2 from svn (at version 423) using the build file - resulted in dist dir from which all artefacts are taken
- Copied jboss-profiler.jar to JBOSS_HOME/bin
- Copied jboss-profiler.properties to JBOSS_HOME/bin
- Copied jboss-profiler-plugins.jar to JBOSS_HOME/bin
- Copied jboss-profiler.sar to JBOSS_HOME/server/default/deploy
- Edited run.bat to include the following line:
set JAVA_OPTS=%JAVA_OPTS% -javaagent:jboss-profiler.jar -Djboss-profiler.properties=jboss-profiler.properties


My jboss-profiler.properties file looks as follows:

  | core=javassist
  | enable=yes
  | cpu=yes
  | memory=yes
  | includes=com.sadalbari.demo.ejb3.*
  | excludes=*
  | visibility=private
  | save=yes
  | startup=yes
  | repository=no
  | remote=yes
  | store=memory
  | location=.
  | host=localhost
  | port=5400
  | ejb=yes
  | servlet=yes
  | jsf=yes
  | jmx=yes
  | rmi=yes
  | corba=yes
  | plugin.1=org.jboss.profiler.plugins.Hibernate
  | 

I then boot jboss.  I notice the following lines on the console which indicate to me that I have configured 'correctly':

  | D:\servers\jboss\jboss-4.2.2.GA\bin>run -b 127.0.0.1
  | ===============================================================================

  | 21:38:08,187 INFO  [Server] Starting JBoss (MX MicroKernel)...

  | 

etc etc

There are no errors in my log file.  

I also have a simple EJB3 session bean which I wish to profile, which starts up correctly.  The bean implementation class is in the package com.sadalbari.demo.ejb3

I then invoke my bean a number of times from a test client.  The bean creates 1000 instances of a POJO class, SomeClass (in the same package) during its invocation.

I then shutdown the server (shutdown.bat -S), at which point the server exits gracefully leaving my with a timestamped .jps file

I then run the command:
java -Xmx512m -Djboss-profiler-client.properties=jboss-profiler-client.properties -jar jboss-profiler-client.jar load <file-name>.jps 
on the file, which produces a directory.

A directory with the timestamped name is created containing the files:
classes.txt
hotspots.txt
methods.txt
overview.txt

and two directories:
classes
threads

The classed directory contains 2 files:
com.sadalbari.demo.ejb3.EJB3SessionBean.txt
com.sadalbari.demo.ejb3.SomeClass.txt

None of these files contain any evidence of a method invocation/thread usage.  For example, overview.txt:


  | From: 17 April 2008 21:38:07:875
  | To  : 17 April 2008 21:44:02:812

I've done a bit of digging/messing and my feeling is that there is something wrong with the MANIFEST of the jboss-profiler.jar file.

This file contains the following entry (on one line)
Boot-Class-Path: jboss-profiler.jar jboss-profiler-connectors.jar jboss-profiler-plugins.jar asm.jar javassist.jar ../lib/javassist.jar jboss-remoting.jar jboss-common.jar concurrent.jar log4j.jar

o Very few of these jars are resolveable from the location in which the startup script is inited (JBOSS_HOME/bin).  
o A number of them don't even exist in jboss (for example jboss-profiler-connectors.jar which _is_ part of the profiler build, but was not mentioned in any setup step)
o Why is asm.jar repeated?

I tried cleaning up as far as possible and pointing to the jars in the jboss installation.  As I went along I got a number of NoClassDefFoundError exceptions, which I resolved by adding the jars to the Boot-Class-Path.  For example, when I resolved the jboss-remoting.jar correctly (I actually just copied the jar to the bin directory), I got

Caused by: java.lang.NoClassDefFoundError: org/jboss/mx/util/JBossNotificationBroadcasterSupport
        at org.jboss.remoting.network.NetworkRegistry.(NetworkRegistry.java:55)

Eventually I got to a point where I got a NPE in the JBoss boot sequence.  

Has anybody got the profiler working properly with JBoss 4.2.2?  Any help would be appreciated.

----
BTW - there is also an error in /JBossProfiler2/src/etc/jboss-service.xml:
false
is repeated twice, once with true, the second time with the value false
