Im amending the Metricbeats data rate visualization to calculate bandwidth rates from my netflow data.

I think ive got the right fields calculated (below), but my results values x10 what they should be.

I'm setting the flow data manually, so i know these should be 1MBs / 4MBs / 8MBs. Below a timelion chart showing the right values.

Any idea why my metric numbers are off?

I think i've hacked this by adding the Calculation:

variable nbytes = Sum of netflow.bytes

params.nbytes / 10

But this seems a bit of a cheat

Are you using the bytes formatter (in the options tab)? Is the result as expected with this switched off?
