When using the docker_stats_exporter from a docker container running on ubuntu 20.04, the container does not start because /usr/bin/docker is not present and the process does not have sufficient rights to create it. Looking in the code, /usr/bin/docker is referred to in Jenkinsfile, but not in docker_stats_exporter.js (only the socket). Removing the volume /usr/bin/docker:/usr/bin/docker made docker_stats_exporter.js run perfectly.

I considered creating a pull request for the README, but I do not really know what the applications of Jenkinsfile are, so I decided to just create this issue to mention it.

I use Grafana to visualize the data exported. I shared the visualization for the container stats of this exporter. Maybe it is useful for someone else as well: https://grafana.com/grafana/dashboards/13331/

BTW: thanks for this really useful exporter

Hi,

Trying to install on Pi 3 and getting an error:
no matching manifest for linux/arm/v7 in the manifest list entries The terminal process "/usr/bin/bash '-c', 'docker compose -f "app/docker-compose.yml" up -d --build'" terminated with exit code: 18.

I thought I had done this on a Pi 3 before with out a problem?
Should this work on buster?

I deployed this in a stack with Prometheus and Grafana. However, there is no data (and no error log either). I also used your Grafana dashboard template with no result.
Here is my docker-compose.yaml:

version: '3'

volumes:
  prometheus-data:
    driver: local
  grafana-data:
    driver: local

services:
  prometheus:
    image: prom/prometheus:latest
    container_name: prometheus
    ports:
      - "9090:9090"
    volumes:
      - /home/sil/prometheus:/etc/prometheus
      - prometheus-data:/prometheus
    restart: unless-stopped
    command:
      - "--config.file=/etc/prometheus/prometheus.yml"

  grafana:
    image: grafana/grafana:latest
    container_name: grafana
    ports:
      - "3030:3000"
    volumes:
      - grafana-data:/var/lib/grafana
    restart: unless-stopped

  docker-stats:
    image: wywywywy/docker_stats_exporter:latest

      - "9487:9487"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    restart: unless-stopped

and my prometheus.yaml:

global:
  scrape_interval:     15s # By default, scrape targets every 15 seconds.

scrape_configs:
  - job_name: 'prometheus'
    scrape_interval: 5s

Hi,

For some hosts docker_stats_exporter metrics are not up to date compare with the current status.

Example: i have 30 containers with status=running and i do not have metrics about them

[root@host]# docker ps | wc -l
32
[root@host]#
[root@host]# curl http://localhost:9487/metrics | grep -v "#"

dockerstats_cpu_usage_ratio{name="XXX",id="4f172ac34142"} Nan

[root@host]# docker logs -f docker-exporter --tail 5
ERROR: TypeError: Value is not a valid number: undefined
ERROR: TypeError: Value is not a valid number: undefined
