That's the behavior I would expect.

Thanks for verifying the behavior.
I did some further testing and found a bug in my openflow controller. Sorry
for bothering you with this...
The flow counters are now updated every second. The port counters seem to
update almost instantaneous (now ping -i 0.01) and measuring every 10ms and
it's u
I ran a test. I set up an Open vSwitch switch (from current Git
"master") between two nodes, connected to "ovs-controller" as an
OpenFlow controller. I ran "ping -i.1" between them, to transmit 10
ICMP echo requests and replies per second. On the switch, I ran
"watch -n1 ovs-ofctl dump-flows br0
2 hosts directly connected to a machine running ovs. The openflow
controller (POX) runs on yet another machine. All bare metal, no VMs.
The goal is to measure the traffic passing through the switch using the
openflow protocol.
Versions:
Open vSwitch 1.7.3
Ubuntu 11.04
Kernel 2.6.38-11-generic-pae
Open vSwitch determines the interval.
What is your test case?

I checked it multiple times and it seems to be 2.5-2.6s on average
openvswitch is polled for its counters using the openflow protocol
Is this interval determined by openvswitch or by the linux kernel?
Thanks!

They should be updated about once a second. I'm surprised that you
see anything different.

Hi,
I'm polling the port the stat counters of openvswitch (with kernel module)
and noticed that they are only updated about every 2.5s.
Is this normal behavior? Is there any way to change this (make it update
more often)?
Thanks in advance!
