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.
I have one of the Nitrokeys and several of the smart cards for various purposes. The software side of using them can be a bit confusing if you're not familiar with HSMs and PKCS#11, but the OpenSC project has a lot of good info to help.
