Hi, Alexandre
I need to generate a log with STP messages
You want to output the log like "[STP][INFO] dpid=0000000000000001:
[port=1] DESIGNATED_PORT / LISTEN" to the log file, right?
The log is output in Stp class in ryu/lib/stplib.py, but currently,
"--log-file" option is not passed to Stp,
so it always logs to stdout.
The quick fix is making handlers to output to the file in Stp.
Also I need to collect the time between the messages
Showing time in logs is enough?
You can do it by putting "%(asctime)s" in the log format.
I attached the quick fix for these to this mail.
Could you try this?
Thanks,
Fujimoto

Hello people,
I need your help. I need to generate a log with STP messages, but when
I use the --log-file = arq.txt option, the STP messages are not
inserted in the file.
Also I need to collect the time between the messages, measure the STP
call time in the SDN Networks - it is a job for the MS in IS.
I read the RYU Book, but I did not find the syntax for these situations
Can you help me ?
Thank you in advance.
