Hi



1) I think that you  need to install either the OpenJVM or the Sun/Oracle JVM, and then set JAVA_HOME to that JVM.






2) and 3) question

Example that you can use with twiddle

To get the active session count for your own app.
./twiddle.sh --user=admin --password=admin --server=127.0.0.1 get jboss.web:type=Manager,path=/jmx-console,host=localhost activeSessions


To retrieve the thread queue size
./twiddle.sh --user=admin --password=admin --server=127.0.0.1 get jboss.system:service=ThreadPool QueueSize


To retrieve active thread counts
./twiddle.sh --user=admin --password=admin --server=127.0.0.1 get jboss.system:type=ServerInfo ActiveThreadCount


To retrieve the amount of free memory
./twiddle.sh --user=admin --password=admin --server=127.0.0.1 get jboss.system:type=ServerInfo FreeMemory


To get all processing stats from the HTTP acceptor on JBoss
./twiddle.sh --user=admin --password=admin --server=127.0.0.1 get jboss.web:type=GlobalRequestProcessor,name=http-127.0.0.1-8080


Invoke a thread dump
./twiddle.sh --user=admin --password=admin --server=127.0.0.1 invoke jboss.system:type=ServerInfo listThreadDump


Invoke a listing of CPU utilization
./twiddle.sh --user=admin --password=admin --server=127.0.0.1 invoke jboss.system:type=ServerInfo listThreadCpuUtilization


Total System memory
./twiddle.sh --user=admin --password=admin --server=127.0.0.1 get jboss.system:type=ServerInfo TotalMemory


Active Thread Count
./twiddle.sh --user=admin --password=admin --server=127.0.0.1 get jboss.system:type=ServerInfo ActiveThreadCount

~
