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).
Follow the instructions here
http://noxrepo.org/noxwiki/index.php/NOX_Installation#Installation (where
it says For a branch other than master...)
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'

You need to write a component that does that by sending query packets from NOX to the switch. (or, if you prefer, you can modify pyswitch to send such queries) You can look at the 'monitoring' component in the netapps folder, which gather statistics from switches, as an example for how to construct and send such query packets.
