Hi @vishutanuku,

For AppDynamics Java agent with Tomcat, you have multiple options to configure proxy settings:

OPTION 1: JVM ARGUMENTS
-----------------------
You can add the proxy settings as JVM arguments in your Tomcat startup script (catalina.sh/catalina.bat or setenv.sh/setenv.bat):

JAVA_OPTS="$JAVA_OPTS -Dappdynamics.http.proxyHost=your_proxy_host -Dappdynamics.http.proxyPort=your_proxy_port"

If your proxy requires authentication, also add:

JAVA_OPTS="$JAVA_OPTS -Dappdynamics.http.proxyUser=your_proxy_username -Dappdynamics.http.proxyPasswordFile=/path/to/password/file"

OPTION 2: CONTROLLER-INFO.XML
----------------------------
Yes, you can add proxy settings directly in the controller-info.xml file, which is located in the agent's conf directory:

xml
<controller-info>
<!-- Other controller settings -->
<http-proxy-host>your_proxy_host</http-proxy-host>
<http-proxy-port>your_proxy_port</http-proxy-port>
<http-proxy-username>your_proxy_username</http-proxy-username>
<http-proxy-password-file>/path/to/password/file</http-proxy-password-file>
</controller-info>

OPTION 3: SYSTEM PROPERTIES
--------------------------
You can also set system-wide proxy settings using standard Java system properties:JAVA_OPTS="$JAVA_OPTS -Dhttp.proxyHost=your_proxy_host -Dhttp.proxyPort=your_proxy_port -Dhttp.nonProxyHosts=localhost|127.0.0.1"

BEST PRACTICES
-------------
1. For security, store proxy passwords in a separate file and use the password file reference
2. Make sure the agent has read permissions for the password file
3. Restart Tomcat after making these changes
4. Check agent logs for any proxy-related connection issues
5. If using HTTPS for the controller, you may also need HTTPS proxy settings

To verify if your proxy settings are working, check the agent logs for successful connection messages to the controller after restart.

These configurations work for both AppDynamics Java agent versions 4.x and 21.x+.
