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.
All you really need is OPI, it will find and add pretty much anything you need.
I find the official wiki, the documentation project and official forums useful, as well as the Arch wiki for general Linux information. I like knowing where to find good, accurate information and help for when I need it.
