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 jumped in several months ago and haven't really regretted it. The caveat being that you have to be okay with learning Nix (the language), debugging with only arcane error messages to go off of, and reading a lot of the config source because documentation is vast but shallow. If you feel like you're willing to make the tradeoff, then it is a blast and you'll be surprised you ever lived without Nix.
In case you want some inspiration or to take an existing config and run, feel free to take a peek at or use mine: https://github.com/jakehamilton/config
