Filter type

MSG Parse: This filter parses message content. Some unifi devices do not have the ability to send host name in the syslog message. When host name is provided if the hostname begins with an upper case U it will be discarded as a “model” number when configuring device names in the NMS use valid RFC dns names (lower case a-z numbers 0-9 and dash).
