[CommunityUser]

Hello everbody,

I just installed RabbitMQ monitoring extension to on a standalone machine agent but I'm getting below error when I start machine agent? Could you please help me.

Thank you.

Hi ,

We see the missing class org.apache.commons.httpclient.HttpConnectionManager is already under <machinaget_dir>/lib/ classpath in jar at path <MachineAgent>\lib\tp\commons-httpclient-3.1.jar , Can you please check whether this jar exists, if not please copy the file at corresponding path to make sure it is in classpath and start machine agent in new terminal or prompt and send us the latest machinne agent logs if issue persists.

Also we request you check the integrity of machineagent archive download from our download site with md5sum or checksum as we see this file exists in our machine agent lib path. Hope that information helps,

Regards,

Arun

Thank you for your kind response . You can see below output about start with httpclient and commons

I can't see commons-httpclient-3.1.jar I also download machine agent 3 days ago from AppDynamics Download page. (https://download.appdynamics.com/onpremise/public/latest/MachineAgent.zip) I'll check again wtih new download of the file.

I put the commons-httpclient-3.1.jar in the tp directory and start within new terminal but still not working.

Kind regards.

Hi,

Keep us posted how it goes with latest version of machine agent archive from our download site, Additionaly you can place the har having the missing class in <rabbitmqmonitor>/monitor.xml file as follows:

 <classpath>rabbitmq-monitoring-extension.jar;commons-httpclient-3.1.jar</classpath>

where commons-httpclient-3.1.jar is placed at <rabbitmqmonitor>/ path, keep us posted how it goes.

Also it looks httpclient-*.jar is from old machineagent version which is not found in our local as well, we expect the issue will be resolved with fresh machinaagent installation using latest version and place rabbitmq monitoring in new installation and see how it goes.

Regards,

Arun

Hello,

This is the output of md5sum  for MachineAgent archive just downloaded it.

[root@dpsrapd01p auyilmaz]# md5sum MachineAgent.zip
aa4230e0f8b38bb4c5b54b4b12f15c66 MachineAgent.zip

 and there isn't commons-httpclient-3.1.jar in /lib/tp directory.

I also tried with new machine agent ant the new rabbitmq monitoring extension but doesn't change anything. I edit the monitor.xml file like you said and it is working now. 

Thank you. 

Best regards.

Hi,

Glad to hear that the edit monitor.xml and adding jar entry had helped to solve the issue.

Regards,

Arun
