Troubleshooting Machine Agent Visibility in Application Containers Tab

[Abhi.Bajaj]

Ensuring Machine Agent Containers Appear in the AppDynamics UI

Containers with APM agents will show up in Application -> Containers view

In this example we have Machine Agent running in Amazon Linux 2

For this to work:

• You should have your App Agent UNIQUE_HOST_ID as the first 12 characters of your container ID
•  Sign in to AppD UI
• Go to Settings wheel icon on top right -> AppDynamics Agent -> App Agent and search for this Agent
• Please confirm the unique-host-id for me
• If the UNIQUE_HOST_ID is the first 12 characters of your Container ID then we would need to pass the below JVM argument and restart your Machine Agent
  -Dappdynamics.docker.container.containerIdAsHostId.enabled=true
• You can pass this JVM argument while starting up the Machine agent
  java -Dappdynamics.docker.container.containerIdAsHostId.enabled=true  -jar machineagent.jar
• Or you can edit the process file at <MA-Home>/bin/machine-agent and edit:
  JAVA_OPTS="$JAVAOPTS -Xmx256m -Dappdynamics.docker.container.containerIdAsHostId.enabled=true"

​In the scenario where your UNIQUE_HOST_ID for Java Agent isn't the first 12 characters of your container ID then please provide the below and file a support ticket with AppDynamics

• docker ps
• cat /proc/self/cgroup
• cat /etc/os-release
• docker exec -it <container-name> hostname
• Share the JVM arguments/configuration properties you are passing
• Support will be able to replicate and help provide a fix

Ideally, your correlation and complete solution should look like the screenshots attached above.
