Verify that the Proxy is Running

The Java proxy is the part of the agent that communicates with the Controller. If the agent is installed in the right place, confirm that the Java proxy is running.
  1. From the command line enter: 
    ps aux | grep java
  2. Inspect the list.
    You should see output similar to the following if the proxy is running: 
    /usr/lib/appdynamics-php-agent/proxy/jre/bin/java -server -Xmx120m -classpath /usr/lib/appdynamics-php-agent/proxy/conf/logging/*:/usr/lib/appdynamics-php-agent/proxy/lib/*:/usr/lib/appdynamics-php-agent/proxy/lib/tp/*:/usr/lib/appdynamics-php-agent/proxy/* -Djava.library.path=/usr/lib/appdynamics-php-agent/proxy/lib/tp -Dappdynamics.agent.logs.dir=/usr/lib/appdynamics-php-agent/logs -Dcomm=/tmp/ad-siJ4rp -DagentType=PHP_APP_AGENT -Dappdynamics.agent.runtime.dir=/usr/lib/appdynamics-php-agent/proxy com.appdynamics.ee.agent.proxy.kernel.Proxy
If you are instrumenting a PHP CLI script, you need to start the proxy manually. You may also need to start the proxy manually if you have special requirements for running Java processes. See Start the PHP Agent Proxy Manually.
