Airflow operator stats

Gather system information about airflow processes.

How to use

• Run airflow_operators_metrics container on each node with airflow workers like:

docker run -d \
    -v /proc:/host/proc:ro \
    -v /etc/hostname:/host/hostname:ro \
    -e CUSTOM_PROCFS_PATH=/host/proc \
    -e HOSTNAME_PATH=/host/hostname \
    mastak/airflow_operator_stats:alpine

• Add scrapper config to the prometheus, docker swarm example:

scrape_configs:
  - job_name: 'airflow-exporter'
    dns_sd_configs:
    - names:
      - 'tasks.airflow-exporter'
      type: 'A'
      port: 8000
