Hi, I have to monitor a PHP application that lives inside a docker container, and I have a couple of begginers doubts.
Can I monitor the application with the agent installed outside the docker container?
the host server of the application (where the PHP agent has to be installed) has the firewalld active, what port should I open for the agent can communicate with the APM server?
this comunication, between the agent and APM server is bi-directional? or the agent just send data and doesn't receives data.
