Hi Ricardo
I've used the nox flow fetcher component and it worked fine for me.
One thing to look at is how you're specifying the ofp_match object while
requesting for flows.
The ofp_flow_stats_request will return counters for flow table entries that
match the specified ofp_match object ?
If there no matching entries in the forwarding table <Flow_stats>flows vector
will be empty.
Hope this helped
Best!

Subject: [nox-dev] Problem in getting flows statistics
Hi,
I am trying to get flows statistics in my C++ component using flow fetcher, but
all fields of flows seems not instanciated. For example, I need to know flow
size, number of packets, number of bytes and other information.
I created a ofp_flow_stats_request request in my component, set it as:
request.table_id = 0xff;
request.out_port = OFPP_NONE; , in datapath_join_event and passed it to
flow_fetcher as a parameter of start_fetch.
But when the handler of Flow_stats_in_event is called, the size of the
vector<Flow_stats> flows still zero as all of it other fields.
Is the error in my request?
Am I missing something?
Sorry if I didn't made myself clear.
Thank you for help.
Regards.
