Transmission Metrics in Grafana

If you use Transmission as your download client, you can use a metrics exporter for Prometheus to ingest info into Grafana to display. You’ll also want to make sure Prometheus is set up and running or else this won’t work!

SSH to your docker host that is running Prometheus and edit the prometheus.yml configuration file by adding the following:

1
scrape_configs:
2
  - job_name: 'transmission'
3
    scrape_interval: 10s
4
    static_configs:
5
      - targets: ['<ip.of.transmission.exporter>:19091']

Save and close prometheus.yml. Now create the Transmission-Exporter.

docker run -d -p 19091:19091 -e TRANSMISSION_ADDR=http://<ip.of.transmission.client>:<port> metalmatze/transmission-exporter

You’ll need to change ipoftransmission:<port> to the ip

transmission_session_stats_downloaded_bytes{type="cumulative"}

You should see something similar to:

Now open Grafana and under Data Sources add a new Prometheus source:

Click Save & Test. If you get an error, make sure Grafana can reach Prometheus.

Adding Transmission Stats to your Dashboard

Navigate to a Dashboard you wish to add Transmission stats to and add a new singlestat panel. Under Metrics, add the following query:

transmission_session_stats_downloaded_bytes{type="cumulative"}

And then under the Options tab select “Average” for Stat and “data(metric)/bytes” under Unit.
