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 haven't used it myself, but a solution with LUKS, TPM2, and clevis is the way I've seen other people set it up https://github.com/latchset/clevis
