    vicky sedfre Newbie

      Hello Everyone.

       

      I am new to JBOSS & in my company JBOSS 4.2.0 is in use currently(old fashined).

       

      Question 1:

      I am trying to run twiddle commands to fetch the Server details  but while executing it is throwing the below exception:Please suggest how to fix this

      ++++++++++++++++++++++++++++++++

      Exception in thread main java.lang.NoClassDefFoundError:/org/jboss/console/twiddle/Twiddle

      Caused by java.lang.ClassNotFoundException: org.jboss.console.twiddle.Twiddle

      at java.net.URLClassLoader$1.run(URLClassLoader.java:202)

      ++++++++++++++++++++++++++++++++

      Question 2: Does Twiddle command can connect on JBOSS JNP port only  or we can use other ports as well

       

      Question 3: How to connect to differen JBOSS server instances running on same JNP port & on same machine using TWIDDLE command

       

      Please help in understand the the above mentioned my naive queries

       

       

      Thanks a lot for your help in advance

          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

          ~                                                                                                                                                                      

          ~
