Hi Theo,
Yup there is a Monitoring.send_flow_stats_request()
Cheers,
Aaron
P.S: here are some hints to get it working if it helps:
import nox.lib.pyopenflow as of
def send_flow_stats_request():
global xid
flows = of.ofp_match()
flows.wildcards = of.OFPFW_ALL ^ of.OFPFW_DL_SRC
match_this_mac = "00:11:22:33:44:55"
flows.dl_src = [int(a[0:2],
16),int(a[3:5],16),int(a[6:8],16),int(a[9:11],16),int(a[12:14],16),int(a[15:17],16)]
inst.Monitoring.send_flow_stats_request(dpid, flows, 0xff, xid);
xid +=1
def flow_stats_in_handler(dpid, flows, more, xid):
print str(dpid) + " " + str(flows)
for i in flows:
print flows[i]
You also have to register it with:
inst.register_for_flow_stats_in(flow_stats_in_handler)
