VnStati Network Statistics
I made this page using vnStat and vnStati. It has been monitoring traffic since 7th March 2015
The graphs are updated by Cron once an hour.
I have made a how to here, if you would like to try this yourself.
Traffic statistics on a hourly basis for the last 24 hours
Traffic statistics on a daily basis for the last 30 days
Traffic statistics on a monthly basis for the last 12 months
All time top 10 traffic days
And this is the live output from vnstat:
