How to instrument WebLogic with JProbe?

There are two ways.

1. Customize startManagedWebLogic.sh with instrumentation.
For instance, for JProbe, we can do the following
${JPROBE}/bin/jplauncher
-jp_java="$JAVA_HOME/bin/java" -jp_input="myapp.jpl" -Dweblogic.Name=${SERVER_NAME} -Dweblogic.management.username=${WLS_USER} -Dweblogic.management.password=${WLS_PW} -Dweblogic.management.server=${ADMIN_URL} -Djava.security.policy="${WL_HOME}/server/lib/weblogic.policy" -Duser.timezone="MST" -Djava.security.auth.login.config="${EM_ABP_HOME}/wl_jaas.config" weblogic.Server

jplaucher will kick off the instrumented JVM.

2. Use a different node manager start up script.
To avoid passing those environment variables as above, use a customized node manager start up script is a good idea.

look at startNodeManager.sh to write your own

nodemanager.properties
======================
StartTemplate=myjprobe.sh


For example, if you set StartTemplate=myjprobe.sh, myjrobe.sh is used to start Weblogic Managed server with jplauncher just like in 1.
