## What it is
cAdvisor (Container Advisor) is a running daemon from Google that collects, aggregates, processes, and exports resource usage and performance statistics for running containers. It provides per-container and machine-wide metrics via a web UI and storage/export plugins, with native Docker support and Kubernetes DaemonSet deployment.

## Use cases
- monitor cpu and memory usage of docker containers
- collect container metrics for prometheus
- track historical resource usage per container
- monitor container performance in kubernetes
- export container network and disk stats
- understand resource isolation parameters of running containers

## When to choose
- you need per-container resource metrics on a docker or kubernetes host
- you want a lightweight single-binary/container monitoring agent that exports to prometheus or other backends
- you need historical resource usage histograms and network stats per container

## When to avoid
- you need full observability with logs, traces, and alerting out of the box
- you monitor non-Linux hosts such as Windows or macOS containers
- you want application-level APM rather than infrastructure metrics

## Facets
- artifact type: service
- maturity: active
- function: monitoring, analytics
- domain: monitoring, cloud-computing
- platform: go, self-hosted
- tags: container-metrics, resource-usage, docker, kubernetes, daemon, prometheus-exporter, containers, devops, linux
