mackerel-plugin-docker

Docker (https://www.docker.com/) custom metrics plugin for mackerel.io agent.

Synopsis

mackerel-plugin-docker [-method=<method>] [-host=<host>] [-command=<docker>] [-tempfile=<tempfile>] [-name-format=<format>] [-label=<key>]
  • -method Specify the method to collect stats, 'API' or 'File'. If not specified, a method is chosen based on docker API version. If the API version is under 1.17, 'File' is used. Otherwise, 'API' is used.
  • -host Socket path. This option is same as --host option of docker command. The default value is unix:///var/run/docker.sock.
  • -command Path to docker command. Without path, binary is searched in the directories named by the PATH environment variable. This is only used when method is 'File'. The default value is docker.
  • -tempfile Temporary file stored metric values for calculating differentials.
  • -name-format Set the name format from name, name_id, id, image, image_id, image_name or label (default "name_id")
  • -label Use the value of the key as name in case that name-format is label.
