Instrumenting a java program using the default java agent

Products

• CA Application Performance Management Agent (APM / Wily / Introscope)
• INTROSCOPE

Issue/Introduction

I have an application which needs the default java agent as there is no application server. Tried to instrument using IntroscopeAgentFiles-NoInstaller10.5.2.52default.unix.tar. So wrote a wee program and wee script with the agent instrumentation. Got no logs and no communication with the EM.

Environment

Any agent version

Resolution

The script looks like:
java HelloWorld -javaagent:/home/wilyserv/wily/Agent.jar -DagentProfile=/home/wilyserv/wily/core/config/IntroscopeAgent.profile

The solution is to use the application at the end of the java arguments in the script as below:
java -javaagent:/export/home/wilyserv/wily/Agent.jar -DagentProfile=/export/home/wilyserv/wily/core/config/IntroscopeAgent.profile HelloWorld
