Docker Visibility Settings

You can configure the following For information about Docker Visibility settings on the Standalone Machine Agent. See also , see Configuring Docker Visibility.




The Machine Agent can monitor up to 120 running containers (depending on the pool size configuration, described below) and does not prioritize. The agent collects metrics from containers that run with a configurable regex. By default, this regex matches processes that are are running with the -Dappdynamics prefix option. If you cannot restart the APM agents, or if you to want to filter APM agents based on another command-line argument, you can override this behavior by editing this regex.

Default = ".*[ ]-Dappdynamics.*"

You can configure this option in the following file: <machine-agent-home>/extensions/DockerMonitoring/conf/DockerMonitoring.yml


Before you edit this file, please review "Editing YML Files: Important Notes" above.

Docker Metric Collector Pool Size

The Standalone Machine Agent can monitor up to 15 containers by default. You can configure the agent to monitor up to 120 containers at the same time: set the pool size to 5 (the default setting is 3). The trade-off is that increasing the pool size will consume more resources on the agent host. 
To change the pool size, set the following. You cannot change this setting in the DockerMonitoring.yml file.

  • System Property - appdynamics.docker.metric.collector.pool.size


Process Limits

Other configurable settings are available in the Controller Admin UI, for example:
