data throughput

Hi

Does anyone know if there is a neat way to see the varnish data throughput per second? We are moving from free varnish to a paid plan and I would like to see if the currently chosen plan will be sufficient for our needs.
Since this is based on Gb/s I want to know how much data is passing by on the varnish server without taking in account data from monitoring and management of the machine itselves. Hence the wish to find some metric inside Varnish, but could not find it yet?

Met vriendelijke groet/Kind Regards

You might want to look at |s_req_hdrbytes + |
||s_req_bodybytes + ||
|||s_resp_hdrbytes| + ||
|||s_resp_bodybytes| ||

varnishstat in curses (interactive) mode will also show a current "change"
value, if your update rate is 1s(detailt), that will be per second.

For longer intervals, I suggest you just snapshot the being/end value and
calculate the average.
