ipvsadm -l --stats

[Rutger van Oosten <r.v.oosten@xxxxxxxxxxx>]

When I run ipvsadm -l --stats it shows connections, packets and bytes in and
out for the virtual services and for the real servers. One would expect that
the traffic for the service is the sum of the traffic to the servers - but
it is not, the numbers don't add up at all, whereas in ipvsadm -l --rate
they do (approximately, not exactly for the bytes per second ones).

For example (LVS-NAT, two real servers, one http virtual service):

# ipvsadm -l --stats
IP Virtual Server version 1.0.10 (size=4096)
Prot LocalAddress:Port               Conns   InPkts  OutPkts  InBytes

# ipvsadm --version
ipvsadm v1.21 2002/11/12 (compiled with popt and IPVS v1.0.10)


Is this a bug, or am I just missing something?

Thanks, Rutger
