1. Introduction
SNMP and SYSLOG are two widely used protocols to communicate event
notifications. Although co-existence of several management protocols
in one operational environment is possible, certain environments
require that all event notifications be collected by a single system
daemon, such as a SYSLOG collector or an SNMP notification receiver,
via a single management protocol. In such environments, it is
necessary to translate event notifications between management
protocols.
The latest version of SYSLOG, specified in [RFC5424], supports a
structured data element format. Structured data elements allow us to
map between SNMP notifications and SYSLOG messages without losing
information. In this memo, we specify a concrete mapping from SNMP
event notifications [RFC3416] into SYSLOG messages [RFC5424]. We
specify how the SYSLOG message format should be utilized to carry the
information contained in an SNMP notification message. A new SYSLOG
structured data element is defined, which carries the PDU portion of
an SNMP notification message.
1.1. Conventions
A system that has the capability of receiving SNMP notification
messages from an SNMP notification originator and sending the SNMP
data contained inside in a SYSLOG message format to a SYSLOG
collector is referred to in this memo as an "SNMP-to-SYSLOG
translator". By definition, such a system should have an SNMP
