Root cause is that there is no get_change_event() method defined for the dx010 platform in the platform's Chassis class, so xcvrd falls back to try the old sfputil plugin, and get_transceiver_change_event() is not implemented there, either.

pmon service will not start on SONiC.master.478-23b0e07d, dx010-4. Is it the same issue?

[jleveque]

@bingwang-ms: I just checked that device, and yes, this issue is present. However, it also appears that there is also a driver or hardware issue with that device, as I see errors like the following:

thermalctld IOError: Failed to read eeprom : [Errno 2] No such file or directory: '/sys/class/i2c-adapter/i2c-12/12-0050/eeprom'

You might want to try rebooting and/or power-cycling the device.

Thanks @jleveque . Already rebooted the DUT, but the issue is still present. The file '/sys/class/i2c-adapter/i2c-12/12-0050/eeprom' is missing on DUT. Is this file included in image?

[jleveque]

@bingwang-ms: No. This is a device file. It should be created by the platform drivers. Either the drivers are not working properly or there is a hardware issue. I would check another device of the same platform running the same version of SONiC to see if the issue exists there, also.
