Internet Speed Test in a Container
Check your internet bandwidth using the Speedtest CLI from a Docker container. You can configure the tool to run periodically and save the results to an InfluxDB for visualization or long-term records.
docker run --rm robinmanuelthiel/speedtest:latestThe result will then look like this:
Running a Speed Test...
Your download speed is 334 Mbps (29284399 Bytes/s).
Your upload speed is 42 Mbps (4012944 Bytes/s).
Your ping is 6.223 ms.Configuration

Grafana and InfluxDB
For a full visualization and long term tracking, I recommend InfluxDB as a time-series database and Grafana as a dashboard engine. Both come in Docker containers, so the whole setup can be achieved by starting a Docker Compose file.

influxdb:To configure Grafana, we need to add InfluxDB as a data source and create a dashboard with the upload and download values. You can find a demo dashboard configuration in the /demo folder.
Hint: The speedtest outputs values as bytes per second. Make sure to divide all values by 125000 in your dashboard to get the Mbps values.
