Sorry to bother you again, i still can't quite get it to work.
I tried to use the method defined there, but the stats always returns empty.
How i tried:
.
.
.
def getPeriodicStats(dp):
"""show periodic stats on screen
:param dp: the datapath from which the stats shall be shown
"""
waiters = {}
while True:
stats = get_flow_stats(dp, waiters)
print stats
time.sleep(1)
.
.
.
def dp_handler(self, ev):
.
.
.
if ev.enter:
self.topo.add_node(ev.dp.id)
thread.start_new(getPeriodicStats, (ev.dp,))
Am i doing something wrong? Also, i'm not sure what is the use for the
waiter dictionary.
