I'd like to collect the bytes sent and received per day or per hour of a server, so I can collect bandwidth requirements.
I figured setting up grafana, graphite and collectd to collect bandwidth usage metrics, but these only show bandwidth usage per second.
Can I use this information to calculate bytes sent in a timeframe or do I need to think of a new solution?
Example of current collected data, eth0 incoming and outgoing bandwidth in bytes per second.
