I am using monitor component in NOX.
==== nox-0.6.0/src/noxcoreapps/examples/monitor.py =====
def aggregate_timer(self, dpid):
flow = ofp_match()
flow.wildcards = 0xffff
self.ctxt.send_aggregate_stats_request(dpid, flow, 0xff)
self.post_callback(MONITOR_TABLE_PERIOD, lambda :
self.aggregate_timer(dpid))
Thanks,
MinChi
