Hi,
I have two problems regarding flows :
1)
Is it that flow expiration information code is not complete in NOX ?
I am unable to find a way to get flow statistics, once the flow is deleted/
ends.
I am using monitor.py as my reference to collect the
statistics.(src/nox/coreapps/
examples)
I am attaching a handler to my module, using the function,
register_for_flow_expired(self, handler) , defined in core.py.
The arguments of "handler" are not specified in the NOX documentation.
i thought it would be asynchronous and called by itself when a flow ends
If some one can tell me, how to call this function.
2)
When i run monitor.py, and look for aggregrate flow stats,there are
0 flows count, 0 packets
Aggregate stats in from datapath 00:23:20:f5:d8:bd
{'packet_count': 0L, 'byte_count': 0L, 'flow_count': 0L}
displayed on the screen,
though I am having a ping (icmp) flow and a tcp connection in the network.
dpctl shows the entries though
./dpctl dump-flows displays the following output :
stats_reply (xid=0x667f0ad8): flags=none type=1(flow)
duration=1s, table_id=0, priority=65535, n_packets=1095, n_bytes=453330,
idle_timeout=5,hard_timeout=0,icmp,in_port=0,dl_vlan=0xffff,dl_src=50:54:00:00:00:06,dl_dst=50:54:00:00:00:09,nw_src=192.168.0.2,nw_dst=192.168.0.4,icmp_type=0,icmp_code=0,actions=outserial8250:
too much work for irq4
