Twiddle feature in Wildfly AS 8.2.0

sridharthiyagarajan Jun 18, 2015 5:16 AM

Hello, I am migrating my application from JBoss 6 AS to Wildfly 8.2.0 AS. JBoss 6 AS has "twiddle" feature to connect to remote JMX server instance. Similarly, in Wildfly 8.2.0 AS, is there an equivalent feature available ? I just came across the blog TWIDDLE STANDALONE - https://developer.jboss.org/people/arnoldjohansson/blog/2012/04/14/twiddle-standalone where this blog explains about the twiddle standalone setup utilizing related JBoss 6 AS specific files integrated with some of the modules of Wildfly 8.2.0. AS.

My question are:

1. Is TWIDDLE or similar feature not available in Wildfly 8.2.0 AS ?

2. If TWIDDLE or similar feature is available in Wildfly 8.2.0 AS, then what is the feature and how to utilize it ?

3. If TWIDDLE or similar feature is not available in Wildfly 8.2.0 AS, then is TWIDDLE STANDALONE mentioned above the only solution to utilize a similar feature in Wildfly 8.2.0 AS ? Please share if any alternative solution is also available.

Please help to understand on the above.

Many thanks.

1) yes we have jboss-cli which is much more powerful command line tool than twiddle ever was
2) jboss-cli
3) i wouldn't go with twiddle standalone as it is just a emulator of old one. just go with jboss-cli.

you can start it by running jboss-cli.bat|.sh in bin folder of wildfly.

Many thanks for the response .. Tomar Cerar. So, remote JMX server instance can be connected and MBeans operations can be managed using jboss-cli.bat. Could you please provide any tutorial related to jboss-cli feature if possible. Many thanks again.

Hello.. I opened jboss-cli.bat in gui mode and could not see any MBeans that application uses but could see them in JConsole. Could you please share any idea on how to invoke an MBean from command prompt using JBoss-cli.

I don't believe you can use arbitrary application MBeans from the CLI, only the JBoss and JVM related ones

Just for my understanding. Why do you need the MBeans feature in jboss-cli if you can do the same via jconsole?

Hello.. I have an application running on JBoss 6 AS and am migrating to Wildfly 8.2.0 AS. It is an EAR application packed with MBeans and twiddle feature was used in JBoss 6 AS for managing MBeans in batch mode. So, am interested to implement the same in Wildfly 8 AS and trying to find a similar feature within Wildfly 8 AS.

It looks like this issue had been raised also in other forums (java - Can jconsole data be retrieved from the command line? - Stack Overflow). There are mentioned some tools which you may find useful. Another option might also be to program such a wrapper by yourself. This should not be to complicate. A working example is also explained in JMX subsystem configuration - WildFly 9 - Project Documentation Editor

Many thanks for the response.. Mayer. So, I understand that in JBoss 6 AS, twiddle feature supported MBeans management from the command line but in Wildfly 8.2.0 AS, there is no such feature available.

The options you mentioned for MBeans management should be used.

1. Using JConsole
2. Using programmatic way

I saw one more option in the JBoss Developer site which is TWIDDLE STANDALONE - https://developer.jboss.org/people/arnoldjohansson/blog/2012/04/14/twiddle-standalone but not sure whether this is reliable solution.

Many thanks for your response.

Yes, you are right. I saw this blog. Obviously Arnold Johansson created a minimal standalone distribution of twiddle.
I am not sure about the argument from Tomaz Cerar.
But I've done some tests and so far it worked fine with wildfly-9.0.0.CR2. So I think this could be an option as well.
