Hello all!
I'd like to send a OFPT_STATS_REQUEST message for a switch for debugging
reasons. In the OF specification it is said the switch must reply wit a
ofp_table_stats message. How can I catch this message in the controller?
Should I subscribe to some kind of eVent like packetin?
Yes.
On the POX manual wiki, see the section ofp_stats_request - Requesting
statistics from switches and especially the subsection Example - Web Flow
Statistics. There's also an extended version of this example called
flow_stats.py in the Third Party section.
