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 don't use the built in reports from PRTG but I've written some custom reporting tools using the PowerShell module, prtgapi (https://github.com/lordmilko/PrtgAPI) which could get you what you're looking for.
