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 ended up writing a little program that injected custom logging rules for every DROP rule. It could be customized pretty easily to fit different requirements. https://github.com/slynn1324/udmp-iptables-log-rules
To make the changes persistent after reboot, you'd need to look into either something external to monitor the device and re-invoke the program - or you could look at https://github.com/boostchicken/udm-utilities to setup persistent scripts that will run on startup.
