    for use with network management protocols in the Internet community.
    In particular, it describes managed objects that can be used to
    manage and monitor MIB objects and take action through events.











Internet Draft      Distributed Management Event MIB        13 June 2003


    The Event MIB provides the ability to monitor MIB objects on the
    local system or on a remote system and take simple action when a
    trigger condition is met.

    The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
    "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this

1.  The SNMP Management Framework

    The SNMP Management Framework presently consists of five major
    components:

     o   An overall architecture, described in RFC 2571 [RFC2571].

     o   Mechanisms for describing and naming objects and events for the
         purpose of management.  The first version of this Structure of
         Management Information (SMI) is called SMIv1 and described in
         STD 16, RFC 1155 [RFC1155], STD 16, RFC 1212 [RFC1212] and RFC
         1215 [RFC1215].  The second version, called SMIv2, is described
         in STD 58, RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and
         STD 58, RFC 2580 [RFC2580].

     o   Message protocols for transferring management information.  The
         first version of the SNMP message protocol is called SNMPv1 and
         described in STD 15, RFC 1157 [RFC1157].  A second version of
         the SNMP message protocol, which is not an Internet standards
         track protocol, is called SNMPv2c and described in RFC 1901

Internet Draft      Distributed Management Event MIB        13 June 2003


         [RFC1901] and RFC 1906 [RFC1906].  The third version of the
         message protocol is called SNMPv3 and described in RFC 1906
         [RFC1906], RFC 2572 [RFC2572] and RFC 2574 [RFC2574].

     o   Protocol operations for accessing management information.  The
         first set of protocol operations and associated PDU formats is
         described in STD 15, RFC 1157 [RFC1157].  A second set of
         protocol operations and associated PDU formats is described in
         RFC 1905 [RFC1905].

     o   A set of fundamental applications described in RFC 2573
         [RFC2573] and the view-based access control mechanism described
         in RFC 2575 [RFC2575].

    A more detailed introduction to the current SNMP Management Framework
    can be found in RFC 2570 [RFC2570].

    Managed objects are accessed via a virtual information store, termed
    the Management Information Base or MIB.  Objects in the MIB are
    defined using the mechanisms defined in the SMI.

Internet Draft      Distributed Management Event MIB        13 June 2003


    This memo specifies a MIB module that is compliant to the SMIv2.  A
    MIB conforming to the SMIv1 can be produced through the appropriate
    translations.  The resulting translated MIB must be semantically
    equivalent, except where objects or events are omitted because no
    translation is possible (use of Counter64).  Some machine readable
    information in SMIv2 will be converted into textual descriptions in
    SMIv1 during the translation process.  However, this loss of machine
    readable information is not considered to change the semantics of the
    MIB.  It may not be possible to meaningfully monitor Counter64
    objects using an SMIv1 version of the MIB.

2.  Overview

    With network sizes well beyond the ability of people to manage them
    directly, automated, distributed management is vital.  An important
    aspect of such management is the ability of a system to monitor
    itself or for some other system to monitor it.

    The Event MIB provides the ability to monitor MIB objects on the
    local system or on a remote system and take simple action when a
    trigger condition is met.

    The MIB is intended to suit either a relatively powerful manager or
    mid- level manager, as well as a somewhat more limited self-managing
    system.

3.  Relationship to Other MIBs

    The Event MIB is based on extensive experience with the RMON MIB
    [RFC1757] and provides a superset of the capabilities of the RMON
    alarm and event groups.  Conceptually, the key extension is the
    ability to allow alarms to be generated for MIB objects that are on
    another network element.  The Event MIB calls "triggers" what the
    RMON MIB called "alarms," but the concepts are the same.  Event MIB
    triggers maintain the RMON handling of thresholds and add the concept
    of booleans.  Event MIB events maintain the RMON concept of sending
    an SNMP notification in response to a trigger and add the concept of
    setting a MIB object.

    The Event MIB is the successor and update to SNMPv2's Manager-to-
    Manager MIB [RFC1451] which was declared Historic pending this work.

    The Event MIB depends on the services of the SNMPv3 Management Target
    and Notification MIBs [RFC2573].

Internet Draft      Distributed Management Event MIB        13 June 2003


    The Event MIB is nicely complemented by the Distributed Management
    Expression MIB [RFC2982], which is the expected source of boolean
    objects to monitor.  Note that there is considerable overlap between
    the wildcard and delta sample capabilities of the Event and
    Expression MIBs.  A carefully-planned implementation might well use
    common code to provide the overlapping functions.

4.  MIB Sections

    The MIB has four sections: triggers, objects, events, and
    notifications.  Triggers define the conditions that lead to events.
    Events may cause notifications.

    The trigger table lists what objects are to be monitored and how and
    relates each trigger to an event.  It has supplementary, companion
    tables for additional objects that depend on the type of test done
    for the trigger.

    The objects table lists objects that can be added to notifications
    based on the trigger, the trigger test type, or the event that
    resulted in the notification.

    The event table defines what happens when an event is triggered:
    sending a notification, setting a MIB object or both.  It has
    supplementary, companion tables for additional objects that depend on
    the action taken.

    The notification section defines a set of generic notifications to go
    with the events and for Event MIB error handling, and it defines a
    set of objects to put in those notifications.

    The following diagram describes the relationships between the tables
    in the Event MIB.

5.  Operation

    The Event MIB is instrumentation for a distributed management
    application that monitors MIB objects.  In its simplest form this
    application monitors individual, local MIB objects, just as an RMON
    probe fulfills the functions implied by RMON's alarm and event
    operation.  Additionally the application can monitor remote objects
    and wildcarded groups of objects.





Expires December 2003                                           [Page 6]





Internet Draft      Distributed Management Event MIB        13 June 2003


    Remote monitoring uses the tag service of the Management Target MIB
    [RFC2573] to select and access remote systems as an ordinary SNMP-
    based management application.  Local monitoring may be via a more
    intimate, local interface which may, for example, bypass SNMP
    encoding but otherwise is functionally identical to remote SNMP
    operation, including the application of access control.  A self-
    management only system MAY not implement remote monitoring.

    Wildcards indicate that the application SHOULD use a GetNext-type
    operation to find the zero or more instances implied by a truncated
    object identifier, just like an ordinary SNMP-based management
    application.  Each instance of a wildcard is treated as if it were a
    separate entry, that is the instances of a wildcarded object are
    independent of one another.  For example, a wild-carded object may
    trigger an event, and result in the setting of another wildcarded
    object.  The instance that satisfied the trigger function is used to
    perform the set function.  All of this takes place independently of
    any additional instances that may fill the wildcard.

    Error handling is by notification.  These error notifications SHOULD
    be enabled only for the diagnosis of problems indicated by error
    counters.  If minimizing the probability of notification loss is a
    concern they SHOULD be transmitted as Inform PDUs as described in the
    [SNMP-TARGET-MIB] or directed to a log as described in the
    Notification Log MIB [rfcNotificationLogMIB].  Note that this does
    not mean the Notification Log MIB is REQUIRED, since in fact
    notifications usually are not lost, but that the Notification Log MIB
    can be helpful with this as well as other MIBs that include
    notifications.

    Although like most MIBs this one has no explicit controls for the
    persistence of the values set in configuring events, a robust, polite
    implementation would certainly not force its managing applications to
    reconfigure it whenever it resets.

    Again, as with most MIBs, it is implementation-specific how a system
    provides and manages such persistence.  To speculate, one could
    imagine, for example, that persistence depended on the context in
    which the expression was configured, or perhaps system-specific
    characteristics of the expression's owner.  Or perhaps everything in
    a MIB such as this one, which is clearly aimed at persistent
    configuration, is automatically part of a system's other persistent
    configuration.

Internet Draft      Distributed Management Event MIB        13 June 2003


6.  Security

    Security of Event MIB entries depends on SNMPv3 access control for
    the entire MIB or for subsets based on entry owner names.

    Security of monitored objects for remote access depends on the
    Management Target MIB [RFC2573].  Security for local access can
    depend on the Management Target MIB or on recording appropriate
    security credentials of the creator of an entry and using those to
    access the local objects.  These security credentials are the
    parameters necessary as inputs to isAccessAllowed from the
    Architecture for Describing SNMP Management Frameworks.  When
    accessing local objects without using a local target tag, the system
    MUST (conceptually) use isAccessAllowed to ensure that it does not
    violate security.

    To facilitate the provisioning of access control by a security
    administrator for this MIB itself using the View-Based Access Control
    Model (VACM) defined in RFC 2275 [RFC2575] for tables in which
    multiple users may need to independently create or modify entries,
    the initial index is used as an "owner index".  Such an initial index
    has a syntax of SnmpAdminString, and can thus be trivially mapped to
    a securityName or groupName as defined in VACM, in accordance with a
    security policy.

    If a security administrator were to employ such an approach, all
    entries in related tables belonging to a particular user will have
    the same value for this initial index.  For a given user's entries in
    a particular table, the object identifiers for the information in
    these entries will have the same sub-identifiers (except for the
    "column" sub-identifier) up to the end of the encoded owner index.
    To configure VACM to permit access to this portion of the table, one
    would create vacmViewTreeFamilyTable entries with the value of
    vacmViewTreeFamilySubtree including the owner index portion, and
    vacmViewTreeFamilyMask "wildcarding" the column sub-identifier.  More
    elaborate configurations are possible.

         "Reasons for failures in an attempt to perform a management
         request.

         The first group of errors, numbered less than 0, are related
         to problems in sending the request.  The existence of a
         particular error code here does not imply that all

         returning that code.

         The second group, numbered greater than 0, are copied
         directly from SNMP protocol operations and are intended to
         carry exactly the meanings defined for the protocol as returned

     DESCRIPTION
         "The type of sampling to perform.

         An 'absoluteValue' sample requires only a single sample to be

         mteTriggerValueID at the sample time.

         A 'deltaValue' requires two samples to be meaningful and is

         samples after the object at mteTriggerValueID is first found

         unsigned values it is always positive, based on unsigned
         arithmetic.  For signed values it can be positive or negative.

         For SNMP counters to be meaningful they should be sampled as a
         'deltaValue'.

         For 'deltaValue' mteTriggerDeltaTable contains further
         parameters.

         If the next sample begins before the previous one completed the

         A frequency of 0 indicates instantaneous recognition of the

         be supported in cases where it makes sense and the system is
         able to do so.  This feature allows the MIB to be used in
         implementations where such interrupt-driven behavior is
         possible and is not likely to be supported for all MIB objects
         even then since such sampling generally has to be tightly
         integrated into low-level code.

         Systems that can support this SHOULD document those cases
