Please confirm the log level of this messages.
Ryu (ryu-manager) does not output messages using "self.logger.debug()" without
"--verbose" option.
"--verbose" means the "debug" log level and the default log level of Ryu is
"info".
Then, you need to use "self.logger.info()" or add "--verbose" option to
ryu-manager.
FYI, ryu-manager with "--verbose" option will output the following messages when
received OFPErrorMsg from switches.
e.g.)
EventOFPErrorMsg received.
version=0x4, msg_type=0x1, msg_len=0x2c, xid=0xea31cff6
`-- msg_type: OFPT_ERROR(1)
OFPErrorMsg(type=0xc, code=0xa,
data=b'\x04\x1d\x00\x20\xea\x31\xcf\xf6\x00\x00\x00\x01\x00\x00\x00\x01\x00\x01\x00\x10\x00\x00\x03\xe8\x00\x00\x00\x00\x00\x00\x00\x00')
|-- type: OFPET_METER_MOD_FAILED(12)
|-- code: OFPMMFC_OUT_OF_METERS(10)
`-- data: version=0x4, msg_type=0x1d, msg_len=0x20, xid=0xea31cff6
`-- msg_type: OFPT_METER_MOD(29)
