Twiddle Standalone

This is a standalone version of the CLI based JMX tool Twiddle by JBoss.

The original Twiddle is a simple but powerful CLI based JMX client often used by e g system administrators to retrieve various JMX data for use in shell scripting.
It is normally bundled with JBoss AS up to community version 6.

As Twiddle - or similar tool - was missing from the JBoss AS7 / WildFly distributions, the need for this type of tool has been in high demand. To remedy this, twiddle-standalone was born.

twiddle-standalone has initially been created by re-packaging the twiddle script (twiddle.sh with some modifications) and required JARs from JBoss AS 6.1.0.Final.
See also JSR-160.

To make twiddle-standalone work for JBossAS7/WildFly - that utilizes the remoting-jmx protocol for external retrieval of JMX values - various new modules (JARs) has been linked in. As these modules vary somewhat between JBossAS7/WildFly distributions, they are currently not part of the twiddle-standalone distribution itself.


Some JAR:s of JBoss AS7 or WildFly are needed for the remoting-jmx protocol to work, so a local (to twiddle-standalone) installation of JBoss AS7 or WildFly is recommended for easy setup. Alternatively, look in $TWIDDLE_HOME/bin/twiddle.sh for the JAR:s needed - they are listed by the MODULES variable - and add them to a location of more convenience to you particular environment and needs.



First set an environment variable JBOSS_HOME to the root of your JBossAS7/WildFly installation, in your shell or the twiddle.sh script itself. E g

export JBOSS_HOME=/opt/wildfly-8.0.0.Beta1


All old twiddle commands should work as before.

Try running twiddle-standalone by executing

twiddle.sh -h

from $TWIDDLE_HOME/bin.

To access and retrieve values from an JBossAS7/Wildfly instance you need to specify the remoting-jmx protocol, like

twiddle.sh -s service:jmx:remoting-jmx:// get java.lang:type=ClassLoading

which (with WildFly 8.0.0.Beta1) would give an output of something like

12:18:21,150 INFO  [xnio] XNIO version 3.1.0.CR7
12:18:21,173 INFO  [nio] XNIO NIO Implementation Version 3.1.0.CR7
12:18:21,212 INFO  [remoting] JBoss Remoting version 4.0.0.Beta1

When running against JBoss/EAP server, please, manually uncomment JBoss section in twiddle.sh


This version of twiddle-standalone has successfully (and unaltered) been tested on OS X 10.9 with Java SE 7 (1.7.0_45) and JBossAS/WildFly 7.2.0 and Wildfly 8.0.0.Beta1
