The Docker EE platform provides a base set of metrics that gets you running and into production without having to rely on external or 3rd party tools. Docker strongly encourages the use of additional monitoring to provide more comprehensive visibility into your specific Docker environment, but recognizes the need for a basic set of metrics built into the product. The following are examples of these metrics: The Docker EE platform provides a base set of metrics that gets you running and into production without having to rely on external or 3rd party tools.
