Hi there, I see the following message:

"Caused by: java.io.IOException: no such process"

Are you sure you have the right process id in the command? on windows you can find the process id using the "tasklist" command.

Kind Regards,

David

Hi David,

Above is Working for me  now, I started my tomcat where my application is running,

Great thanks, you're missing a crutical argument (after the process id), see below:

java -Xbootclasspath/a:"C:/Program Files/Java/jdk1.8.0_151/lib/tools.jar" -jar C:/appdynamics/AppServerAgent-4.5.8.25115/javaagent.jar 14760 appdynamics.controller.hostName=somehost,appdynamics.controller.port=someport,appdynamics.controller.ssl.enabled=false,appdynamics.agent.accountAccessKey=somevalue,appdynamics.agent.applicationName=Doughuts,appdynamics.agent.tierName=DT1,appdynamics.agent.nodeName=DN1,appdynamics.agent.accountName=someaccount

Kind Regards,

David
