[JMXMon Samples Collector] > ERROR > Always getting an error reading samples

[tjn...@gmail.com]

Hello,

I'm trying to use the JMXMon component to get some JMX metrics from a weblogic server.

I follow the JMXMon component documentation in order to configure the component, however when I try to use it I have hallways the following error:

 - 2013/10/13 01:46:54 ERROR - kg.apc.jmeter.jmxmon.JMXMonSampler: "xx.xxxx.xxxx.xxxx.xxxxx":type=*,name="DatabaseQueriesExecuting"

Can anyone help with this problem? I have no ideia how to solve it...

Thanks

Hi,

Can you see JMX Counters with standard JDK JConsole tool ?

If not, i think you need some weblogic specifics jars and add this weblogic jars in the <JMETER_HOME>/lib

Then the JMXMon could retrive Weblogic JMX attributs

If you sucess please add your solution in this thread forum.

For example to monitor JBoss 7, i add  jboss7-client.jar because the JMX procotole is not RMI/JRMP but SOAP.

Yes, with jConsole I can see the counters.

I used the following command to start jConsole:

jconsole -J-Djava.class.path=%JAVA_HOME%\lib\jconsole.jar;%WL_HOME%\server\lib\wljmxclient.jar -J-Djmx.remote.protocol.provider.pkgs=weblogic.management.remote

In <JMETERS_HOME>/lib I have the following jar file: wlfullclient.jar

I also try to include only the wljmxclient.jar used to start the jConsole, but when I try to run the JMXMon sampler I have the following exception:

ERROR - jmeter.JMeter: Uncaught exception:  org.omg.CORBA.NO_PERMISSION:   vmcid: 0x0  minor code: 0  completed: No

I manged to resolve the CORBA.NO_PERMISSION problem. The user that is used to must belong to the Monitors group in the weblogic. The user that I have used in the previous tests only belongs to the administrators group.

Ok so the current status is:

 - In <JMETER_HOME>\lib I have the following jar file: wlfullclient.jar

 - Now I'm trying to read object JMSSessionRuntimeMBean.Consumers with attribute MessagesReceivedCount (I got this values from jConsole). 

 - JMXMon gives me the following error:

     ERROR - kg.apc.jmeter.jmxmon.JMXMonSampler: Key properties cannot be empty 

This means that the Key column should be filled? 

From the documentation this column only needs to be filled in certain cases, and from jConsole, I don't need to put nothing here for this object.

Hi,

Did you use the last version of JMXMon because this error message is not declare in the source code ?

https://github.com/undera/jmeter-plugins/blob/master/extras/src/kg/apc/jmeter/jmxmon/JMXMonSampler.java

Use a version after the 1st October from the download page
http://jmeter-plugins.org/downloads/all/

like the jmeter-plugins-extras-1.1.1-1.1.1.zip-2013-10-05_06-14.zip file or after

Regards.

Thanks Vicent,

I continue to have the problem related with the CORBA.NO_PERMISSION using the last version of the JMX Mon.

I found this link from IBM: http://www-01.ibm.com/support/docview.wss?uid=swg21228701 

In my test plan i have a JMS Publisher sampler and a JMX Mon. listener. If I start jmeter and run the test only with the sampler active, then after a few successfully sent requests I can stop the test and activate the JMX Mon. and the listener works fine.

If I start jmeter and run the test with the sampler and listener activated, then I have the CORBA.NO_PERMISSION exception.

Anyone has this problem?

There is any way to overcome this? In some tests I want to have only the listener working with a dummy sampler for example (to simulate monitoring mode only).

Thanks a lot for any comment
