Internet Draft Event MIB 21 November 1997
1. Abstract
This memo defines an experimental portion of the Management Information
Base (MIB) for use with network management protocols in the Internet
community. In particular, it describes managed objects used for
managing monitoring of MIB objects and taking action through events.

2. The SNMP Network Management Framework
They are: The SNMP Network Management Framework presently consists of
three major components. They are:
the SMI, described in RFC 1902 [1] - the mechanisms used for
describing and naming objects for the purpose of management.
the MIB-II, STD 17, RFC 1213 [2] - the core set of managed objects for
the Internet suite of protocols.
the protocol, RFC 1157 [3] and/or RFC 1905 [4], - the protocol for
accessing managed objects.
The Framework permits new objects to be defined for the purpose of
experimentation and evaluation.
2.1. Object Definitions
Managed objects are accessed via a virtual information store, termed the
Management Information Base or MIB. Objects in the MIB are defined
using the subset of Abstract Syntax Notation One (ASN.1) defined in the
SMI. In particular, each object type is named by an OBJECT IDENTIFIER,
an administratively assigned name. The object type together with an
object instance serves to uniquely identify a specific instantiation of
the object. For human convenience, we often use a textual string,
termed the descriptor, to refer to the object type.

3. Overview
This MIB is based heavily on the RMON and Manager-to-Manager MIBs. It
depends on the services of the Target, Notification, and Expression
MIBs.
All of this must suit either a relatively powerful manager or mid-level
manager, as well as a somewhat more limited self-managing system.
4. Known Problems
The error code for a failure comes from a now non-existent MIB. I
suppose those codes will need to be transplanted here.
The error handling depeds somewhat on notifications and had assumed the
existence of a logging MIB, which evaporated as did the above-mentioned
error codes.
The description of RMON-like threshold operation is broken and needs to
be changed to be like RMON.
The compliance section is missing.
