Do a 'show logging | begin Trap' on your device, see if it is "link up" and has actually sent any syslog to the destination. Should look like something below;
| Trap logging: level notifications, 16 message lines logged | |
| Logging to 192.168.0.51 (udp port 514, audit disabled, | |
| authentication disabled, encryption disabled, link up), | |
| 1 message lines logged, | |
| 0 message lines rate-limited, | |
| 0 message lines dropped-by-MD, | |
| xml disabled, sequence number disabled | |
| filtering disabled |
If all of that checks out, please put up your kiwi syslog configuration text file so we can see what your input syslog filters are (Are you watching for all syslog, only certain levels/facilities, what's it supposed to do it the input, etc). Thanks,
