This module fetches metrics from Docker containers. The default metricsets are:
image metricset is not enabled by default.
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
The Docker module supports the standard configuration options that are described in Modules. Here is an example configuration:
metricbeat.modules: - module: docker metricsets: - "container" - "cpu" - "diskio" - "event" - "healthcheck" - "info" #- "image" - "memory" - "network" #- "network_summary" hosts: ["unix:///var/run/docker.sock"] period: 10s enabled: true # If set to true, replace dots in labels with `_`. #labels.dedot: false # If set to true, collects metrics per core. #cpu.cores: true # 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"
This module supports TLS connections when using
