Docker Integration — Guance Docs

The Guance Docker integration reads container stats straight from the Engine API and cgroups, so CPU throttling and OOM-adjacent memory pressure show up before the container dies — the two traps that mislead host-level monitoring. One input block covers every container on the host; the compose-based reference stack and throttle deep-dives are in the guide below.

Spec	Detail
Collector	DataKit input `docker`
Protocol	Docker Engine API / containerd + cgroup stats
Key metrics	per-container CPU, memory (incl. limit & throttle events), network I/O, restart state
Prerequisites	Access to the Docker socket or containerd endpoint
Dashboard	Pre-built Docker dashboard, auto-installed on first data
Deep dive	Docker Monitoring Guide

Set up in minutes — install DataKit, enable the docker input, and your first Docker metrics appear in Guance within about a minute. Full field list and alert-rule templates live in the Docker Monitoring Guide.
