If you have PHP CLI applications and an Apache web server on the same machine, your setup depends on whether you want all the traffic reported against a single Splunk AppDynamics node or separate nodes. A separate proxy is required for each Splunk AppDynamics node that you want to monitor in the controller.

If you want all the CLI traffic to be reported against one node and all the web traffic to be reported against a different node, configure Apache to auto-launch the proxy (the default) and configure CLI to use a manually-launched proxy. This requires separate .ini files: one for the web PHP with agent.auto_launch_proxy set to 1 and another for PHP CLI with agent.auto_launch_proxy set to 0.

If you want the web traffic and the CLI traffic to be reported against the same node, configure both Apache and CLI to use the same manually launched proxy.
