Data format: Re: Data format

Tue, 16 Mar 2010 06:52:48 +0000

I don't have an official document yet. Will create one.
In short, the format is either of following three:

For Collection or array, it's [ ele1, ele2, …], the expression of element follows same rules
For Map, it's { key1 = value1, key2 = value2, …}, the expression of key and value follows same rules
For others, it's what toString() returns.

To list running JVMs, Jmxterm needs jars from JDK_HOME/lib that doesn't exist in JRE. Is the java command that you ran from a JDK or JRE? For example, …/jdk1.6.0/bin/java is good, …/jdk1.6.0/jre/bin/java or …/jre1.6.0/bin is bad. If you are not sure, run "which java" and let me know the result. Thank you.

Hi,

I'm controlling jmxterm from a Python script, and I'd like an automated way to funnel the data returned in Python objects. What is the data format that is used to return the values?

Thanks,

Mark

Executing several commands in non-interactive-mode: Re: Executing several commands in non-interactive-mode

I should document it somewhere. The delimiter is &&, not ;

Executing several commands in non-interactive-mode: Executing several commands in non-interactive-mode

Wed, 18 Nov 2009 12:42:06 +0000

Hi,

I'd like to execute several commands when using Jmxterm in non-interactive-mode. First I'd like to connect (via "open") and then I'd like to get the value of a mbean. I tried

 echo "open 7358; get java.lang:type=Runtime Name" | java -jar jmxterm-1.0-alpha-4-uber.jar -n

but didn't succeed. Cause I only have the pid of the process I'm not able to open the connection with "-l". Besides that also wouldn't help me with executing other commands than "open".

Many thanks in advance!

ActiveMQ and jmxterm: Re: ActiveMQ and jmxterm

Aside from the purpose, ActiveMQ or arbitrary object, MBean is simple conception for remote object with attributes, operations and notifications. What exactly is the object name and operation that you want to call?

"run browse myprop LIKE 'foobar_%'" calls operation browse("myprop", "LIKE", "'foobar_%'") of selected bean, is it the right operation you attempt to call?

That sounds very helpful. I'd like to add this script that creates RPM to source repository, and start including RPM file as part of release. Is the script available somewhere? Thanks!

I deploy software to RHEL and Fedora systems, and needed an RPM to bundle up this tool. I've written one to publish the .jar file to /usr/share/jmxterm, and dump a shell script called /usr/bin/jmxterm. Does anyone want it?

Setting MBean: Re: Setting MBean

Fri, 24 Jul 2009 06:42:09 +0000

Did you try escaping dash with \? I never had a name with dashes but \ can escape white space without problem.

So try "bean module\-name=cluster". If you still see an error, please feel free to report a bug in http://wiki.cyclopsgroup.org/jmxterm:support. Thanks.

Setting MBean: Re: Setting MBean

Wed, 22 Jul 2009 12:59:26 +0000

Actually, the real MBean name has a hypen, e.g:

foo-baa.xyz.cluster:module-name=cluster

Looking at PATTERN_PROPERTIES in the source, it uses the word regex "\w", I don't think this allows for hyphens although I haven't coded in java in a long time.

Setting MBean: Setting MBean

Wed, 22 Jul 2009 12:13:14 +0000

I'm trying to test jmxterm, unfortunately I can't set the MBean (although I can set the domain). From the below output of "beans" what exactly is the "bean" command to set the MBean to that showed below?

$>domain foo.baa.cluster
#domain is set to foo.baa.cluster
$>beans
#domain = foo.baa.cluster:
foo.baa.cluster:module-name=cluster
$>

No matter what arguments I pass to the "bean" command I always get a Bean name isn't valid error.

I All,

I have an ActiveMQ enviroment. I'd like to use jmxterm for quering my 'FOO.BAR' queue.

I need to retrieve all messages matching a condition on a custom message property (e.g. in my messages the myprop property can assume the values foobar_1,….,foobar_N).

I tried to call:
run browse myprop LIKE 'foobar_%'

but it doesn't work, instead it works perfectly e.g. in jconsole :(

Someone can help me?

Building on top of jmxterm: Re: Building on top of jmxterm

Wed, 10 Sep 2008 06:09:40 +0000

jmxterm is built by maven2, groupId=org.cyclopsgroup and artifactId=jmxterm. Check out
http://repo1.maven.org/maven2/org/cyclopsgroup/jmxterm/

So far I didn't intend to exposed public API for people to extend. I thought the best way to call JMX programmatically is to call javax.management.remote directly. However most classes are public(http://cyclopsgroup.org/projects/jmxterm/apidocs/index.html) and you are always free to call them directly. If you do, you will take the risk of API signature change in future releases.

Can you talk a little more about the use case for public API usage? So that we can figure out the best way to handle it together.

I'd like to build some command line tools on top of jmxterm. Is there a public API I can use to do this?

Also, is jmxterm available in any Maven Repositories so that I can add a dependency to my pom?

I am fairly new to the world of Java. I just recently figured out how to add a simple MXBean interface to my POJOs. About an half an hour ago I asked Google if there was a command line alternative to JConsole. Now I have an easy interface to all the functionality of my simple Java class and all I had to do was download one jar. Thank you for making this great tool available.
