Monitor Weblogic through the command line

Everything that is visible through the Weblogic admin console (http://localhost:7001/console) can be accessed through a command line java tool. This tool can be used to gather data about the weblogic servers via scripting.  There are at least two ways to get runtime monitoring data about weblogic processes. This document covers the use of the java classes that get information from management beans (mbeans). There is also a java tool that allows for browsing the mbean tree like an ftp client: Weblogic Scripting Tool (WLST).

There is a script for setting the CLASSPATH and PATH so that this tool can work. On pitblade (WL Server), the setWLSEnv script is /dsk2/local/bea81/weblogic81/server/bin/setWLSEnv.sh

pitblade:II:root: > source setWLSEnv.sh

CLASSPATH=/dsk2/local/bea81/jdk141_02/lib/tools.jar:/dsk2/local/bea81/weblogic81/server/lib/weblogic_sp.jar:
