InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
If you have some time you could use librespeed-cli instead of the current docker image which contains bloated js stuff you don't use and Ookla's speedtest which is closed source (and given how their website is shit, I wouldn't use their products).
