Abstract
This MIB module defines textual conventions to represent Facility and
Severity information commonly used in syslog messages. The intent is
that these textual conventions will be imported and used in MIB
modules that would otherwise define their own representations.

1. The Internet-Standard Management Framework
For a detailed overview of the documents that describe the current
Internet-Standard Management Framework, please refer to section 7 of
RFC 3410 [RFC3410].
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. MIB objects are generally
accessed through the Simple Network Management Protocol (SNMP).
Objects in the MIB are defined using the mechanisms defined in the
Structure of Management Information (SMI). This memo specifies a MIB
module that is compliant to the SMIv2, which is described in STD 58,
RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
[RFC2580].
2. Background
Operating systems, processes, and applications, collectively termed
"Facilities" in the following, generate messages indicating their own
status or the occurrence of events. These messages have come to be
known as syslog messages. A syslog message in general will contain
among other things a code representing the Facility that generated
the message and a code representing the Severity of the message. The
Facility and the Severity codes are commonly used to categorize and
select received syslog messages for processing and display. The
Facility codes have been useful in qualifying the originator of the
content of the messages but in some cases they are not specific
enough to explicitly identify the originator. Implementations of the
syslog protocol [RFC5424] that contain structured data elements
(SDEs) should use these SDEs to clarify the entity that originated
the content of the message.
This document defines a set of textual conventions (TCs) that can be
used to represent Facility and Severity codes commonly used in syslog
