Problems of virtual machine traffic statistics

[echoes]

I want to count the total export flow of virtual machine. How to count this?

the 'status' api call contains a field for each nic with 'netin' and 'netout' e.g.

qm status 100 --verbose

nics:
        tap100i0:
                netin: 115745307
                netout: 482164

note that this field resets when the vm is shutdown

Can we not reset it?

no that cannot be manually reset and it will always be reset when the interface is gone (i.e. the vm is shutdown)

You might want to build a queue with two values. One for longterm and one for last boot. In the last boot queue you always overwrite with the currently measured value. If the last measured value is zero or lower than whats stored in the last boot queue, add last boot to the longterm qeue and reset the last boot queue to zero.
Your grand total will then be the sum of the last boot and longterm value.
