Docker monitoring with Netdata
Docker Engine is an open source containerization technology for building and containerizing your applications.
This module monitors one or more Docker Engine instances, depending on your configuration.
Metrics
All metrics have "docker." prefix.
| Metric | Scope | Dimensions | Units |
|---|---|---|---|
| containers_state | global | running, paused, stopped | containers |
| healthy_containers | global | healthy | containers |
| unhealthy_containers | global | unhealthy | containers |
| images | global | active, dangling | images |
| images_size | global | size | B |
Configuration
Edit the go.d/docker.conf configuration file using edit-config from the
Netdata config directory, which is typically at /etc/netdata.
cd /etc/netdata # Replace this path with your Netdata config directory
sudo ./edit-config go.d/docker.conf
jobs:
- name: local
address: 'unix:///var/run/docker.sock'
- name: remote
address: 'tcp://203.0.113.10:2375'
For all available options see module configuration file.
Troubleshooting
To troubleshoot issues with the docker collector, run the go.d.plugin with the debug option enabled. The output
should give you clues as to why the collector isn't working.
First, navigate to your plugins' directory, usually at /usr/libexec/netdata/plugins.d/. If that's not the case on your
system, open netdata.conf and look for the setting plugins directory. Once you're in the plugin's directory, switch
to the netdata user.
cd /usr/libexec/netdata/plugins.d/
sudo -u netdata -s
You can now run the go.d.plugin to debug the collector:
./go.d.plugin -d -m docker
