description:
 Monitors the local Docker daemon on a host running the {check_docker.py} agent
 plugin. The plugin talks to the Docker Engine API over the local socket using
 only the Python standard library.

 The service is {CRIT} when the daemon cannot be reached. Otherwise it reports
 the server version, storage and logging driver, Swarm state and the number of
 images, containers, running containers, Go routines, open file descriptors and
 event listeners as metrics.

 Optional upper levels for Go routines and file descriptors, and the handling of
 daemon warnings (OK / WARN / CRIT), can be configured with the rule set
 "Docker daemon info".

item:
 None. One service {Docker Info} per host.

discovery:
 One service is created if the {docker_info} section is present.
