1.  Introduction

   Operating systems, processes and applications generate messages
   indicating their own status or the occurrence of events.  These
   messages are useful for managing and/or debugging the network and its
   services.  The BSD syslog protocol is a widely adopted protocol that
   is used for transmission and processing of the messages.

   Since each process, application and operating system was written
   somewhat independently, there is little uniformity to the content of
   syslog messages.  For this reason, no assumption is made upon the
   formatting or contents of the messages.  The protocol is simply
   designed to transport these event messages.  No acknowledgement of
   the receipt is made.

   Essentially, a syslog process receives messages (from the kernel,
   processes, applications or other syslog processes) and processes
   those.  The processing involves logging to a local file, displaying
   on console, and/or relaying to syslog processes on other machines.
   The processing is determined by the "facility" that originated the
   message and the "severity" assigned to the message by the facility.

   We are using definitions of syslog protocol from RFC5424 [RFC5424] in
