## Definition
|
||
cAdvisor（Container Advisor）是 Google 开发的容器指标采集器，实时采集容器（Docker）的资源使用和性能数据，提供容器级别的监控。
|
||
|
||
## Key Metrics
|
||
- **CPU**：CPU 使用率、限制、throttling
|
||
- **内存**：使用量、限制、缓存
|
||
- **网络**：入站/出站流量、丢包
|
||
- **文件系统**：容器日志大小
|
||
- **容器元数据**：镜像、启动命令、标签
|
||
|
||
## Docker 部署
|
||
```yaml
|
||
cadvisor:
|
||
image: gcr.io/cadvisor/cadvisor:latest
|
||
ports:
|
||
- "8080:8080"
|
||
volumes:
|
||
- /:/rootfs:ro
|
||
- /var/run:/var/run:ro
|
||
- /sys:/sys:ro
|
||
- /var/lib/docker/:/var/lib/docker:ro
|
||
```
|
||
|
||
## Common Alert Rules
|
||
- 容器重启次数 > 0（1 小时内）
|
||
- 容器 CPU 限制超过 90%
|
||
- 容器内存限制超过 85%
|
||
|
||
## Default Port
