Docker Engine collector
Docker Engine
is the industry’s de facto container runtime that runs on various
Linux (CentOS, Debian, Fedora, Oracle Linux, RHEL, SUSE, and Ubuntu) and Windows Server operating systems.
This module will monitor one or more Docker Engines
applications, depending on your configuration.
Requirements
- Docker with enabled
metric-address
Metrics
All metrics have "docker_engine." prefix.
Metric | Scope | Dimensions | Units |
---|---|---|---|
engine_daemon_container_actions | global | changes, commit, create, delete, start | actions/s |
engine_daemon_container_states_containers | global | running, paused, stopped | containers |
builder_builds_failed_total | global | build_canceled, build_target_not_reachable_error, command_not_supported_error, dockerfile_empty_error, dockerfile_syntax_error, error_processing_commands_error, missing_onbuild_arguments_error, unknown_instruction_error | fails/s |
engine_daemon_health_checks_failed_total | global | fails | events/s |
swarm_manager_leader | global | is_leader | bool |
swarm_manager_object_store | global | nodes, services, tasks, networks, secrets, configs | objects |
swarm_manager_nodes_per_state | global | ready, down, unknown, disconnected | nodes |
swarm_manager_tasks_per_state | global | running, failed, ready, rejected, starting, shutdown, new, orphaned, preparing, pending, complete, remove, accepted, assigned | tasks |
Configuration
Edit the go.d/docker_engine.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_engine.conf
Needs only url
to docker metric-address
. Here is an example for 2 docker instances:
jobs:
- name: local
url: http://127.0.0.1:9323/metrics
- name: remote
url: http://203.0.113.10:9323/metrics
For all available options, please see the module's configuration file.
Troubleshooting
To troubleshoot issues with the docker_engine
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.
Navigate to the
plugins.d
directory, usually at/usr/libexec/netdata/plugins.d/
. If that's not the case on your system, opennetdata.conf
and look for theplugins
setting under[directories]
.cd /usr/libexec/netdata/plugins.d/
Switch to the
netdata
user.sudo -u netdata -s
Run the
go.d.plugin
to debug the collector:./go.d.plugin -d -m docker_engine
