Docker moduleedit

This module fetches metrics from Docker containers. The default metricsets are: container, cpu, diskio, healthcheck, info, memory and network. The image metricset is not enabled by default.

Compabilityedit

The Docker module is currently tested on Linux and Mac with the community edition engine, versions 1.11 and 17.09.0-ce. It is not tested on Windows, but it should also work there.

Module-specific configuration notesedit

It is strongly recommended that you run Docker metricsets with a period that is 3 seconds or longer. The request to the Docker API already takes up to 2 seconds. Specifying less than 3 seconds will result in requests that timeout, and no data will be reported for those requests.

Example configurationedit

The Docker module supports the standard configuration options that are described in Specify which modules to run. Here is an example configuration:

metricbeat.modules:
- module: docker
  metricsets:
    - "container"
    - "cpu"
    - "diskio"
    - "healthcheck"
    - "info"
    #- "image"
    - "memory"
    - "network"
  hosts: ["unix:///var/run/docker.sock"]
  period: 10s
  enabled: true

  # If set to true, replace dots in labels with `_`.
  #labels.dedot: false

  # To connect to Docker over TLS you must specify a client and CA certificate.
  #ssl:
    #certificate_authority: "/etc/pki/root/ca.pem"
    #certificate:           "/etc/pki/client/cert.pem"
    #key:                   "/etc/pki/client/cert.key"
