Why does CPU goes beyond 600 while using cadvisor

docker-compose.yml

version: '3.7'
services:
  cadvisor:
    image: google/cadvisor
    volumes:
      - /:/rootfs:ro
      - /var/run:/var/run:rw
      - /sys:/sys:ro
      - /var/lib/docker/:/var/lib/docker:ro
      - /cgroup:/sys/fs/cgroup:ro
    ports:
      - 8080:8080
    privileged: true
    command:
      - --allow_dynamic_housekeeping=true
      - --housekeeping_interval=30s
      - --global_housekeeping_interval=2m
      - --disable_metrics=disk,tcp,udp
      - --docker_only=true
    restart: always
    deploy:
      mode: global

I have disabled most of the flags.I run it with privileged mode yet I see spikes in CPU.How do I make it consume less CPU?

I get the following error too

W0505 06:22:01.988235       1 raw.go:87] Error while processing event ("/sys/fs/cgroup/blkio/system.slice/systemd-tmpfiles-clean.service": 0x40000100 == IN_CREATE|IN_ISDIR): inotify_add_watch /sys/fs/cgroup/blkio/system.slice/systemd-tmpfiles-clean.service: no such file or directory

Sure , let me try, thanks
Hi,

Giving the cpus limit it not working, my container does not start when i give cpu limit.

`failed to create service monitor_cadvisor: Error response from daemon: rpc error: code = InvalidArgument desc = invalid cpu value 0.0001: Must be at least 0.001`

Even after i made both the limits for cpu to 0.001 my container does not start. Can you please help with this?
Hi,

Don't give fraction value. At least give 1 or 2 CPUs. If you get an error, then paste your complete code here.
Below is my code:

cadvisor:
    image: gcr.io/google-containers/cadvisor:latest
    networks:
      - monitor
    command: ["-logtostderr", "-v=4", "-docker_only", "-storage_duration=2m0s"]
    privileged: true
    devices:
      - /dev/kmsg
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - /:/rootfs:ro
      - /var/run:/var/run
      - /sys:/sys:ro
      - /var/lib/docker/:/var/lib/docker:ro
      - /dev/disk:/dev/disk:ro
      - /sys/fs/cgroup:/cgroup:ro
    deploy:
      mode: global
      resources:
        limits:
          cpus: '0.001'
          memory: 128M
        reservations:
          cpus: '0.001'
          memory: 64M

Hi,

I tried with the below code. It is working totally fine.

version: '3.2'
services:
   cadvisor:
    image: google/cadvisor:latest
    container_name: cadvi
    ports:
    - 8080:8080
    volumes:
    - /:/rootfs:ro
    - /var/run:/var/run:rw
    - /sys:/sys:ro
    - /var/lib/docker/:/var/lib/docker:ro
    deploy:
        mode: global
        resources:
          limits:
            cpus: '0.01'
            memory: 128M
          reservations:
            cpus: '0.001'
            memory: 64M

In your code, you have set limits for CPUs and reservations for CPUs the same. That is why you got an error. Set the below values and try once.

 limits:
            cpus: '0.01'
            memory: 128M
          reservations:
            cpus: '0.001'
            memory: 64M

Hi@Isabel,

I don't know about container advisor tool, but I used this below code and it works fine in my system.

  • First create one folder.
  • Inside that folder create one file name prometheus.yml file and write down the below code.
scrape_configs:
- job_name: cadvisor
  scrape_interval: 5s
  static_configs:
  - targets:
    - cadvisor:8080
  • Inside that same folder create another file name docker-compose.yml and write down the below code.

version: '3.2'
services:
  prometheus:
    image: prom/prometheus:latest
    container_name: prometheus
    ports:
    - 9090:9090
    command:
    - --config.file=/etc/prometheus/prometheus.yml
    volumes:
    - ./prometheus.yml:/etc/prometheus/prometheus.yml:ro
    depends_on:
    - cadvisor
  cadvisor:
    image: google/cadvisor:latest
    container_name: cadvisor
    ports:
    - 8080:8080
    volumes:
    - /:/rootfs:ro
    - /var/run:/var/run:rw
    - /sys:/sys:ro
    - /var/lib/docker/:/var/lib/docker:ro
    depends_on:
    - redis
  redis:
    image: redis:latest
    container_name: redis
    ports:
    - 6379:6379
  • Now run docker-compose up and browse http://localhost:8080.

My cadvisor is up and running.I only have concern with CPU usage.I'm monitoring around 2k containers.
Set threshold value of RAM and CPU to your container.
