JMX - Monitor JBoss

Warning

This serves as a workaround because connecting to a JBoss application is not officially supported by the JMX plugin.

Versions used Copied

Steps Copied

  1. Enable JBoss’s management and admin console.
  2. Extract JBoss’s jboss-cli-client.jar file.
  3. Transfer the jboss-cli-client.jar file to the Netprobe host.
  4. Add the path of that file to the Netprobe’s GENEOS_JARS variable.

For example:

## 64-bit JMX Server settings
#JAVA_VENDOR=oracle
export JAVA_HOME=/etc/alternatives/jre_openjdk
export JRUN=${JAVA_HOME}/lib/amd64/server
export GENEOS_JARS=${NP_HOME}:/opt/geneos/jboss_client_jar
export GENEOS_LIBS=${NP_LIB}

In the example above, /opt/geneos/jboss\_client\_jar is the path to the jboss-cli-client.jar.

  1. Restart the Netprobe.
  2. Check if the jboss-cli-client.jar file is loaded by looking at the -Djava.class.path= log entry in the Netprobe log.

  1. Configure the JMX sampler.

Extracting MBean objects and attributes Copied

JConsole is needed to extract JBoss MBean objects and attributes.

  1. Transfer the jboss-cli-client.jar file to a host that has JConsole.
  2. Open a command prompt (for example, cmd).
  3. Go to the JConsole’s directory.
  4. Execute the following command:
jconsole -J-Djava.class.path="<JAVA_HOME>\lib\tools.jar";"<JAVA_HOME>\lib\jconsole.jar";"<JBoss client path>\jboss-cli-client.jar"

For example:

jconsole -J-Djava.class.path="C:\Program Files\Java\jdk1.8.0_231\lib\tools.jar";"C:\Program Files\Java\jdk1.8.0_231\lib\jconsole.jar";"C:\Program Files\Java\jboss_client_jar\jboss-cli-client.jar"
  1. Input the following connection details in JConsole:
["Geneos"] ["Geneos > Netprobe"] ["FAQ"]
