Java agent on Jetty 9.3

[Salih.Tilkici]

Hi,

Trying out the Java agent using Jetty 9.3/ JDK8.

Agent is dowloaded and installed inside the location /opt/appdynamics/appagent

Inside the jetty jvm.ini file I have the following defined

[message redacted to protect privacy]

But I don't see any date pushed, neither I see any log file created.

What did I missed in the setup?

[Peter.Holditch]

I noticed that your ps output is missing the "appagent" part from the argument to -javaagent.

This raises the question why your JVM starts at all, since it should fail to start if it cannot find the configured agent.

You don't have a second agent install at /opt/appdynamics, with some agent logs written beneath it do you?

Warm regards,

Peter

For some reason, wrong ps output was copied in, here the correct one

[message redacted to protect privacy]

Any update on this?

[Peter.Holditch]

To diagnose why the agent isn't reporting to the controller, you need to diagnose why it isn't generating any logs, to troubleshoot.

Does the "bambooa" user have permission to write log files to the directory under the /opt/appdynamics/appagent/ver4.x.y.z/logs directory?

What happens if you run "java -javaagent:/opt/appdynamics/appagent/javaagent.jar -Dappdynamics.agent.nodeName=telematicsmm13 -Dappname=telematicsmm13 -Dappdynamics.agent.tierName=test -Dconfig.home=/opt/apps/telematicsmm13 -Dappdynamics.agent.applicationName=b2c -version"

Does the agent connect then?

[Salih.Tilkici]

Hi,

yes the bambooa user has access to write to the logs location.

java -javaagent:/opt/appdynamics/appagent/javaagent.jar -Dappdynamics.agent.nodeName=telematicsmm13 -Dappname=telematicsmm13 -Dappdynamics.agent.tierName=test -Dconfig.home=/opt/apps/telematicsmm13 -Dappdynamics.agent.applicationName=b2c -version

This one I got to work. There was some issue in the first xml line with the double quotes

<?xml version=“1.0” encoding=“UTF-8"?>

Corrected that and then it was workign fine for the standalone Java command

I will restest the Jetty one and keep you ifnormed later thsi evening.

I have tested with this java command with success, the agent is used and logs are created, some defaults are taken from the config XML file

java -javaagent:/opt/appdynamics/appagent/ver4.5.4.24355/javaagent.jar -Dappdynamics.agent.nodeName=telematicsmm13  -version

Now I added the same logic to my Jetty environment, Jetty 9.3 and Java 8.

We are using the startd.d location for the module ini files, so the JVM arguments need to be specified inside the file jvm.ini.

# ---------------------------------------
# Module: jvm
# ---------------------------------------
--module=jvm

--exec

-javaagent:/opt/appdynamics/appagent/ver4.5.4.24355/javaagent.jar
-Dappdynamics.agent.nodeName=telematicsmm13
