[Observium] Question about traffic graphs

Hi,

My data center bills me based on 95th percentile and Mbps, but Observium shows traffic as bits/second.

My monthly allowance is 100Mbps, how would I convert that to the bits/second in 95th? They also state they bill me on bandwidth utilization, not data used.

Finally, they state they use 5 minute intervals for data collection, I guess that's also called 'polling' if I'm not mistaken? I could not find any info on how often the data is collected.

Just to clarify, if I got the calculation right - 100Mbps = 30TB /mo (rounded off).
