Hi,
I think best way is to use BPF to collect stats. I did this in past in
combination
with 'perf'.
Theres a nice book of Brandon Greg from Netflix Networks where he
describe how to do this and how to write own scripts.
merry Xmas

Hi All,
I am trying to collect memory, disk and network stats for a VM on kvm
host. It
seems that the statistics are not matching what the OS inside the
VM is reporting. Why is this discrepancy ?
Is this a known bug of libvirt ? Also I heard that libvirt shows
cumulative figures for these measures ever since the VM was created. Also
I tested by creating a new vm and comparing the stats without a reboot .
Even in this case, the stats dont agree. Can someone help me here please ?
Thanks
Kumar
