How to do a "local connection" like VisualVM does?: Re: How to do a "local connection" like VisualVM does?

I'm not sure how VisualVM works but listing JVM processes(started with same run as user) is supported in JDK(like in jps or jconsole). Jmxterm takes advantage of this feature and allows you to list pids or connect to a pid.

In Jmxterm, you may use jvms command to list all running JMV processes started with current user and use open command to open it. For example

$>jvms
5641 ( ) - jmxterm-1.0-alpha-3-uber.jar
20276 ( ) - org.eclipse.equinox.launcher_1.1.1.R36x_v20101122_1400.jar -os linux -ws gtk -arch x86 -showsplash -launcher /opt/local/eclipse/eclipse-java-helios-SR2-linux-gtk/eclipse -name Eclipse —launcher.library /opt/local/eclipse/eclipse-java-helios-SR2-linux-gtkplugins/org.eclipse.equinox.launcher.gtk.linux.x86_1.1.2.R36x_v20101019_1345/eclipse_1310.s -startup /opt/local/eclipse/eclipse-java-helios-SR2-linux-gtkplugins/org.eclipse.equinox.launcher_1.1.1.R36x_v20101122_1400.jar -exitdata 72800b -product org.eclipse.epp.package.java.product -vm /opt/local/sun/jdk1.7.0/bin/java -vmargs -Dosgi.requiredJavaVersion=1.5 -XX:MaxPermSize=256m -Xms40m -Xmx384m -jar /opt/local/eclipse/eclipse-java-helios-SR2-linux-gtk//plugins/org.eclipse.equinox.launcher_1.1.1.R36x_v20101122_1400.jar

VisualVM automatically lists the Java processes running on my local box, and I just double-click my appserver instance in the list, and I can see my jmx mbeans. I can't figure out how to do something equivalent with jmxterm. How do I connect to a local instance with jmxterm?

I've had good luck wrapping the commands in a bash script, though this technique isn't peculiar to any particular shell:

#!/bin/bash
/opt/yaddayadda/java -jar
/opt/sumthin/utilities/jars/jmxterm-1.0-alpha-4-uber.jar«EOF
open localhost:1234
domains
quit
EOF

somehow I need to stop the '&' from being recognized as a delimiter

I'm trying to set the jmxproperty to a value that has multiple "=" in the string. For example: open PID && bean BeanName && set propertyX queryString?arg1=x&arg2=y&arg3=z && bye | java -jar jmxterm-1.0-alpha-uber.jar -n

Data format: Re: Data format

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.

#UnsupportedOperationException: Operation requires JDK instead of JRE.
I'm using java:

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

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

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

Mon, 31 Aug 2009 20:26:14 +0000

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?
