Configuration

Environment variables

TA_URL: The URL to your TubeArchivist Server
TA_KEY: Your TubeArchivist API key
LISTEN_PORT: The listen port for the metrics server to run on. Defaults to 9934
POLL_INTERVAL: The interval in seconds for the data to be scraped from ElasticSearch. Defaults to 60

Running via Docker Compose (supported)

This metrics service is designed to be ran inside of docker.

To view the main compose file for TubeArchivist, please see the main repository here: TA Repo

To add the metrics service in, place this into your compose file and update the environment variables as required.

services:
  archivist-metrics:
    image: bbilly1/tubearchivist-metrics
    container_name: archivist-metrics
    restart: always
    environment:
      - "TA_URL=http://tubearchivist.local"
      - "TA_KEY=yourtaapikey"
      - "LISTEN_PORT=9934"
      - "POLL_INTERVAL=60"
    ports:
      - 9934:9934

Running via Standalone

Should you want to, you can install and run this without docker.

To do so, clone this repo, install the python libraries with pip3 install -r requirements.txt

then run python3 tubearchivist-metrics/main.py

Environment variables can be passed in via normal syntax for your OS.

Prometheus example config

      - job_name: 'tubearchivist-metrics'
        metrics_path: /
        static_configs:
          - targets:
              - <server>:9934

How are metrics gathered?

Typically, a prometheus server will poll the HTTP endpoint of the metrics service to obtain its metrics.

In most scenarios, a service will then retrieve the data for the metric, and then respond to the prometheus http call. However this can be quite harsh on databases and applications, especially when prometheus is polling every 15 seconds.

To prevent performance issues and unncessecary load on ElasticSearch. We prefetch the metric information from the API every 60 seconds (default). The metric is then updated on the HTTP endpoint after we have retrieved the data and cached for prometheus to scrape.

This means prometheus can scrape the endpoint every second if it likes, but no database calls to the API will be made until the polling interval is reached.

If you require more granular polling, you can update the POLLING_INTERVAL environment variable
