The syslog file on the machine running kiwisyslog shows:
2014-06-30 14:04:25 Local7.Notice c-office-chg1 7285: Jun 30 14:04:21.357 CSD: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet1/0/1, changed state to down
2014-06-30 14:04:28 Local7.Error c-office-chg1 7286: Jun 30 14:04:22.355 CSD: %LINK-3-UPDOWN: Interface FastEthernet1/0/1, changed state to down
It's not filtering out the message or as I explained discarding the message.
