Kibana version: 7.17.5

APM Agent language and version: 1.6.2

Original install method (e.g. download page, yum, deb, from source, etc.) and version: Curl from "https://github.com/elastic/apm-agent-php/releases/download/v1.6.2/apm-agent-php_1.6.2_all.deb

Fresh install or upgraded from other version? fresh

Is there anything special in your setup? the apm-server is installed as a service in the host, and the agent is installed on docker
Description of the problem including expected versus actual behavior. Please include screenshots (if relevant): No data has been received from agents yet.

deleted and prune all older images and containers, docker-compose build, and docker-compose up.

Hi.

Do you also set some php.ini files to communicate the data to the APM server?

elastic_apm.server_url="http://link-to-apm-server-or-container.ext:port"
elastic_apm.secret_token="Your uber secret token"
elastic_apm.service_name="Name of Application"
elastic_apm.environment="staging"

There is also an APM container needed to receive the data. Do you have to running also?
