I’m looking for an easy way to collect upload/downloads usage stats for traffic flowing through my internet interface on my RB750. (v6.46)
My ISP doesn’t provide this info and I would like to start tracking my usage.
I can view bandwidth graphs but am looking for a way to track upload/download sizes for the day/month.
Started looking at IP / Traffic Flow and NetFlow, but isn’t there a simple way to do this?
The interface menu retains total bytes/packets in/out for each interface. You can copy out the numbers on the first of each month than zero it for next month.
If router is not rebooted for all month 
I have a script which is exporting RX/TX values twice a day to a file on MTiK.
When I need statistics, just download the file on my computer and process it within excel to get information needed.
Since MTiK file size shouldn’t be more that 4 kb, another script warns me when file reaches 3.5 kb.
Thanks, didn’t think about the TX/RX values on the interface. I will look into exporting those into a DB and can then mess around with them.
One nice thing I will never hesitate to say about using MT gear over the past 12 years is that gratuitous reboots have rarely been an issue, especially where you employ a UPS.
My very first MikroTik was installed in the desert, at the top of a windmill. Used to operate 11 months straight without a break inside a metal enclosure, 0-49°C outdoor temp (hotter in the box), until seasonal monsoon storms hit the area each autumn and town experienced total power outages.
Also have look at IP Accounting.
Over 100 days uptime and I had to restart it yesterday.
HAP AC, 2.4 and 5 GHz links up, clients were disconnected while connected through 5 GHz link, forgot what was the error in the log 
anyway working normally after reboot
Somehow related to the original post, I discovered that adding registered devices to IP/Kid Control, offers some stats (bytes up/down, rates up/down) about each device activity, stats that are still there after a reboot. Stats can be reset manually via Reset Counter button. In a relatively stable environment (let’s say household) with 99% of devices known and registrable, I think it’s a good way to monitor monthly traffic, totally or per device.
