Hi folks,
I've installed AppDynamics machine agent in a docker container on one of our docker hosts:
docker run -d --name sys_appd_machine_agent \ -v /:/hostroot:ro \ -v /var/run/docker.sock:/var/run/docker.sock \ --restart always \ -m 256m \ -e "JAVA_OPTS=-Xms64m -Xmx256m" \ -e "APPD_HOST=hostname" \ -e "APPD_PORT=8090" \ -e "APPD_ACCOUNT_NAME=username" \ -e "APPD_ACCESS_KEY=key-key-key" \ -e "APPD_SSL_ENABLED=false" \ appd-machine-agent:4.5.5.1784
Following exception was thrown for each of the container on the host:
16:51:32,762 WARN [Docker-Monitoring-0] DockerRegistrationTask - Error registering containerId : a5fefcc9cd6d8e1ca24b0a09ac2e15bedebfdb3e38d6f6eb98359ee686e48be3 with error {} com.appdynamics.voltron.rest.utils.RestException: The requested object was not found.

As expected docker container metrics are emtpy in AppDynamics container for the host.
What is wrong there?
Kind regards
Artem

The error message states :
Container registration without application app agent is not supported yet
It appears to us that you have not installed an app agent in your environment. You need to install an app agent inside each container you want to monitor. Please see the Container Monitoring documentation for details.
