How to monitor JBoss using JMX

Steps:

1. Download and install the aforesaid versions.

For the JRE, please ensure that you are using Oracle's JRE. The command, java -version, will tell us whether the JRE used is from Oracle or is from OpenJDK. See example below:

- Oracle Java

$ java -version
java version "1.8.0_60"
Java(TM) SE Runtime Environment (build 1.8.0_60-b27)
Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)

- OpenJDK Java

$ java -version
openjdk version "1.8.0_131"
OpenJDK Runtime Environment (build 1.8.0_131-b12)
OpenJDK 64-Bit Server VM (build 25.131-b12, mixed mode)

2. Enable JBoss EAP's remote monitoring via JMX.

3. Extract the JAR file, jboss-client.jar from $JBOSS_HOME/bin/client.

4. Put the jboss-client.jar on the same directory as the geneos-plugins.jar. For example:

$ pwd
/opt/geneos/binaries/netprobe64/prod
$ ls -l
total 44516

-rw-r--r-- 1 sandbox sandbox 17681211 Jan 16 17:18 jboss-client.jar

-rw------- 1 sandbox sandbox 2649 Jan 16 17:45 nohup.out

-rwxr--r-- 1 sandbox sandbox 45 Dec 26 17:05 toolkit_variable_resolution.bash

5. Start the Netprobe.

6. Configure a JMX-Generic sampler. Some notes:

- Use the serviceURL setting. The format is: service:jmx:remote+http://<JBoss hostname/IP>:<JBoss JMX port>. E.g. service:jmx:remote+http://pabo:9990

- Use the JConsole included in the JBoss EAP to extract the said MBeans.

- Sample configurations: Config 1, Config 2

- Some JBoss MBeans have alternate MBeans. See below:

Use the alternate.mbean value if the ObjectName (actual MBean name) value does not work.
