Docker Exporter (logporter)

Source code: https://github.com/Lifailon/logporter

logporter

A simple and lightweight alternative to cAdvisor for getting basic and custom Docker containers metrics (e.g. container uptime and number of logged messages).

Why collect log counts?

Compare the increased load with the number of logged messages.
If the application is not resource-intensive, the number of logged messages will show the increased load.
Speed up log analysis by displaying at what point in time the most messages were received from the standard and error stream.

Install

Run the exporter in a container using an image from Docker Hub:

docker run -d --name logporter \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -p 9333:9333 \
  --restart=unless-stopped \
  lifailon/logporter:latest

Connect the new target in the prometheus.yml configuration:

scrape_configs:
  - job_name: logporter
    scrape_interval: 10s
    scrape_timeout: 10s
    static_configs:
      - targets:
        - localhost:9333
