I've not had a chance to look into this problem though it has been
fairly widely reported. If someone could try and debug what is going
on, that would be great. Else, we'll get around to it during the next
dev push.
Hi Yu-Chieh Chou,
I cant solve this problem, so I use flowfetcher to get these infos.

Hi all, I also use NOX Virtual Test Environment.
And the aggregate value returns from switch is always zero.
The dpctl dump-aggregate works correctly.
Have someone solve this problem?
Thanks.

Hi Guanyao, I have tested dpctl on switch openflow and it show
me the stats about aggregating flows perfectly.
I used the secchan, dpctl e openflow_mod.ko available in NOX
Virtual Test Environment setup.
But the monitor component continue showing all values with
zero :(

I guess it depends on whether dpctl dump-aggregate works
correctly.
My problem with it is that sometimes it can not aggregate
flows
according to the specified wildcard. I guess this depends on
configuration of switches.
