Trying to figure out daily/weekly/monthly bandwidth usage on my #OpenBSD router... so far, got `pflow(4)` up and runnning as well as `snmpd(8)` with `nfsen` and `mrtg` which lets me see nice graphs of traffic, but I haven't yet figured out how to see a number of bytes transferred per day in/out of my router. My ISP sends me a nice report of this, but I want to verify their numbers with my own. What am I missing? #cluestick #netflow #router
