[Observium] Question octets to Mbps conversion.

Hi,

I am using below query to convert ifInOctets_rate to Mbps value.

mysql> SELECT ifInOctets_rate, CONCAT(ROUND((ifInOctets_rate*8)/1024/1024,2), " Mbps") ConvertedValue FROM `ports-state` WHERE port_id=105; +-----------------+----------------+ | ifInOctets_rate | ConvertedValue | +-----------------+----------------+ | 55014356 | 419.73 Mbps | +-----------------+----------------+

The value I get different from the value printed on the graph for the same port_id. On the graph I got 427Mbps, while this conversion gives me 419.

Since I don't know where in the code this conversion happens, I couldn't figure out if this is the way to go about it or not.

Could someone shed some light?

Thanks
