Docker module

edit

This module fetches metrics from Docker containers.

The Docker module is currently not tested on Windows.

Module-specific configuration notes

edit

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 configuration

edit

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", "memory", "network"]
  hosts: ["unix:///var/run/docker.sock"]
  period: 10s

  # 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"
