This module sends log messages as UDP datagrams to the address and port specified. UDP is the transport protocol of the legacy BSD Syslog standard as described in RFC 3164, so this module can be particularly useful to send messages to devices or Syslog daemons which do not support other transports.
The module will connect to this IP address or DNS hostname.
The module will connect to this port number on the remote host. The default is port 514.
This optional directive specifies the local port number of the connection. If this is not specified a random high port number will be used, which is not always ideal in firewalled network environments.
This optional directive sets the socket buffer size (SO_SNDBUF) to the value specified. If this is not set, the operating system default is used.
