I have an issue with our device send logged to Graylog but not show src address. It show only timestamp “Oct”. Please kindly help check to configure below:
SW#sh run | in logg
logging buffered 409600
no logging console
logging facility local5
logging source-interface Vlan1
logging 10.10.10.1
ntp logging
SW#sh run | in time
service timestamps debug datetime msec localtime show-timezone
service timestamps log datetime msec localtime show-timezone
I guess that your messages are not following the syslog framework. But without sharing information what device you use or without sharing any information that is all just guessing,
