## Overview
|
||
|
||
cAdvisor 是 Google 开发的容器监控工具，自动采集单个节点上运行的所有容器的资源使用情况（CPU、内存、网络、磁盘 I/O），并以 Prometheus 可抓取的格式暴露指标。
|
||
|
||
**采集指标示例：**
|
||
- `container_cpu_usage_seconds_total` — 容器 CPU 使用
|
||
- `container_memory_usage_bytes` — 容器内存使用
|
||
- `container_network_receive_bytes_total` — 容器网络接收
|
||
- `container_last_seen` — 容器最后活跃时间
|
||
- `container_restart_total` — 容器重启次数
|
||
|
||
**典型部署：**
|
||
- Docker: `gcr.io/cadvisor/cadvisor:latest`
|
||
- 端口：`8080`
|
||
- 需要挂载：`/var/run`（Docker socket）、`/sys`、`/var/lib/docker/`
|
||
|
||
**关键告警规则示例：**
|
||
- 容器异常退出: `increase(container_last_seen[5m]) == 0`（容器未上报即可能已退出）
|
||
|
||
**安全注意：** 需审慎挂载 Docker socket（权限等同于宿主机 root）
