Thanks for your kindness.
But there is not exsisting monitoring.py of netapps/
so there is existing some derectory in netapps as a below.
""""
src/nox/netapps# ls
Makefile.am __init__.py bindings_storage discovery hoststate networkstate routing switch_management tablog topology
Makefile.in authenticator data flow_fetcher lavi route storage switchstats tests user_event_log
""""
additionally, I re-write some code(0xfffffff) in monitor.py refering mail. as a below,
"""
def aggregate_timer(self, dpid):
flow = ofp_match()
#flow.wildcards = 0xffff
flow.wildcards = 0xffffffff
self.ctxt.send_aggregate_stats_request(dpid, flow, 0xff)
self.post_callback(MONITOR_TABLE_PERIOD, lambda : self.aggregate_timer(dpid))
"""
1.What does 0xfffffff mean ?
and then, I re-run command.
So, I can check below message.

제목: Re: [nox-dev] gathering status of Openflow Switch
Hi,
I was actually referring to netapps/monitoring/montoring.py, which is a more complete (and complicated) monitoring component, but it is the same idea. However the one you looked at might actually be a better example exactly because it is simpler, but still shows how to create and send switch query packets.
The output you pasted looks okay

Hi,
after I found monitoring.py, There is existing /src/nox/coreapps/examples/monitor.py. I think what you mean is /src/nox/coreapps/examples/monitor.py. right ?
so, I excuted monitor component.
I can check Table stats and Port stats, Aggregate stats as a below.

Hi,
the 'monitoring' component I was referring to, is under: / src / nox / netapps / monitoring / monitoring.py
but on the Destiny branch of the repository (not Zaku which is the master branch).
to switch to Destiny.
-> you mean pyswitch can gather status of flow, port in switch, right ?
and I think I should use ofp_stats_request, ofp_stats_reply, ofp_desc_stats, ofp_port_stats_request, ofp_ports_stats etc of struct in openflow.h and core.py

Exactly. You can see some example of how to build some messages in 'monitoring.py'
