I'm finally testing out these SNMP monitors. I'm sure PRTG will have all kinds of reporting features for a lot of folks, but its UI is really the pits. For real-time stats reporting (not simply generating a report output file to print) it lacks the ability to report based on month or week. Kind of critical if you ask me.

When you select the month view it will show you the current month broken down by day and you can scroll to the bottom to see the totals. When you pick year it still breaks it down by day. Ugh.

The UI for PRTG was just too much to get through. This is PRTG Grapher by the way. The Monitor wasn't useful at all since it seems to be only web-based and it never did do anything with my router.

Byte-o-Meter seems a lot more basic but gets the job done. Including immediately auto-detecting the router and the correct interface to monitor.

The problem however is that it's buggy as hell and just crashes all the time. Great.
