java version support issue?

Hi, I am trying out app dynamics pro, but it seems like i keep losing connection to the jvm agent. It will work for a minute or 2, then go away. If I restart the jvm, it starts reporting again but then drops off.

I didn't find anything of interest in the logs, but I have an idea of why it's not working - our application is run under java6 but still (for the short term) compiled with java5. Could this be the issue, or should it continue to work under this situation?

Also, I signed up for this a few days before thanksgiving, which was a bad move as i didn't really get to try it out fully and now only have 8 days left on the trial. Is there a possibility of getting an extended free trial?

Hi Jesse,

Can you please send the zipped version of <agent_install_dir>/logs we would like to go through the logs to see if there are network connectitivity errors or any agent related errors in agent.log files, Also can you send the screenshots from controller UI depicting the issue for more clarity?, we confirm we do not such intermitent issues from agent/controller end.

Regarding extending trial license you can either file a support ticket at https://help.appdynamics.com/tickets/new Or email to help.appdynamics.com, also we request you to get in touch with your sales representative regarding license regarding this.

Keep us posted the requested information to assist you faster.

Thanks,

Arun

also the memory capture tools don't seem to work at all. again, i assume this is because of our java5/java6 weirdness

Hi Jesse,

We see the following errors in agent logs frequently apart from the latest agent logs, we suspect this is period you are seeing the issue where agent reporting is down intermetently:

====================
[AD Thread-Metric Reporter0] 26 Nov 2013 17:00:12,176 ERROR MetricHandler - Error reporting metrics
java.lang.NullPointerException
    at com.singularity.ee.agent.commonservices.metricgeneration.metrics.o.a(o.java:102)
[AD Thread-Metric Reporter0] 26 Nov 2013 17:16:02,084  WARN MetricHandler - Metric Reporter Queue full. Dropping metrics.
..
[AD Thread-Metric Reporter0] 02 Dec 2013 14:08:58,443 ERROR MetricHandler - Error reporting metrics
java.lang.NullPointerException
===========================

We apologize for the inconvenience here we have known bug in 3.7.11.1 agent version, we request you to either downgrade agent version to 3.7.9 Or you can upgrade the agent version to 3.7.12 agent version to resolved above errors to resolve the agent metrics reporting issue, you can still you the same controller version or you can upgrade to 3.7.12 controller version which is latest version

regarding the missing memory data structure stats under node dashboard in UI not reporting issue, we see that you are using open-jdk which is not supported as per docs http://docs.appdynamics.com/display/PRO13S/Supported+Environments+and+Versions#SupportedEnvironments... , and we can see the same in agent.logs:

===========================

[Thread-0] 02 Dec 2013 15:25:42,424  INFO InstanceCountingManager - Object instance counting could not be started. This feature is currently only supported for Sun JVMs. If you are using a Sun JVM and see this message, please make sure you are either using the JDK (and not JRE), or you must add tools.jar to your JVM classpath if using a JRE.

==========================

On a side note:
We see that you are using controller host as paid29.saas.appdynamics.com, and we account name "blackbaud"
let us know if this is the controller URL: blackbaud.saas.appdynamics.com

Let us know if that information helps.

Thanks,

Arun
