问题复现

今天想折腾下Grafana+cadvisor+Prometheus的组合来监控下服务器的Docker应用

但部署cadvisor时出现了点问题：

Docker命令：

bash

docker run \
  --volume=/:/rootfs:ro \
  --volume=/var/run:/var/run:rw \
  --volume=/sys:/sys:ro \
  --volume=/var/lib/docker/:/var/lib/docker:ro \
  --volume=/dev/disk/:/dev/disk:ro \
  --publish=9101:8080 \
  --detach=true \
  --name=cadvisor \
  google/cadvisor:latest

容器启动失败：

    log
  
    F1006 07:45:20.802587       1 cadvisor.go:146] Failed to create a Container Manager: mountpoint for cpu not found

查了一下ds和bing，结论是Ubuntu24使用了cgroup v2，但cAdvisor依然尚不支持

~~那很糟糕了~~

遂有此文

解决方案

参考这篇博文 ~~（CSDN难得有好文章）~~

编辑GRUB文件其实是一个相当危险的行为，请量力而行

编辑文件

编辑如下文件：/etc/default/grub

~~（要碰我不熟悉的Linux了，好害怕）~~

diff

## 重启 ~~瑟瑟发抖地~~在终端中敲下了：

    bash
  
    sudo update-grub #必须要有这一步
sudo reboot

## 验证万幸启动成功了

可以看见cAdvisor启动成功

Ubuntu24解决安装cAdvisor提示找不到 CPU 的挂载点错误

If your computer has multiple operating systems installed, then you

probably want to run os-prober. However, if your computer is a host

for guest OSes installed via LVM or raw disk devices, running

os-prober can cause damage to those guest OSes as it mounts

filesystems to look for things.

Uncomment to enable BadRAM filtering, modify to suit your needs

This works with Linux (no patch required) and with any kernel that obtains

the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)

Uncomment to disable graphical terminal

The resolution used on graphical terminal

note that you can use only modes which your graphic card supports via VBE

you can see them in real GRUB with the command `vbeinfo'

Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux

Uncomment to disable generation of recovery mode menu entries

Uncomment to get a beep at grub start
