unable to configure jboss profiler.
HI all,
I am trying to configure jboss profiler (1.0 CR4) on jboss 4.2.3 AS. I followed the below steps.
1. copy jboss-profiler-noAOP.sar to the JBoss AS deploy directory
2) put jbossInspector.dll in your PATH (Windows)
or libjbossInspector.so in your LD_LIBRARY_PATH (Linux/Unix)
3) copy jboss-profiler.war to the JBoss AS deploy directory
Configuration:
1) Add something like this to the JBoss JVM options: -XrunjbossInspector:/tmp/profiler,include=com.unisys,ignore=*,memory=false
Make sure the output directory (/tmp/profiler in this example) exists.
Usage:
1) In the jmx-console, use the jboss.profiler Native-profiler mbean to activate profiling
2) Exercise your application
3) In the jmx-console, use the jboss.profiler Native-profiler mbean to stop profiling (if you forget to do this, you will
probably get a java.io.EOFException when you try to use the analyzer war)
4) Analyze results using the JBoss Profiler web app at localhost:8080/jboss-profiler
Example analysis:
a. Click on 'Runtime Profiler'
b. Enter the output directory, for example, /tmp/profiler
c. Check 'Stack on methods', uncheck other options and submit
d. Click 'click here'
e. Click the 'All Methods' link to get a view of time allocation among individual methods
But i am stuck at step 2 itself.
I am unable to load the jbossInspector.dll probably. I have copied jbossInspector.dll to C:\windows\system32 folder. To check the installation of jbossInspector.dll i tried the below
C:\Users\Administrator>java -XrunjbossInspector:\tmp Foo
Error occurred during initialization of VM
Could not find agent library jbossInspector on the library path, with error: %1 is not a valid Win32 application
And when i try to invoke the activate mbean, i get the below error.
