Status of This Memo

   This document specifies an Internet standards track protocol for the
   Internet community, and requests discussion and suggestions for
   improvements.  Please refer to the current edition of the "Internet
   Official Protocol Standards" (STD 1) for the standardization state
   and status of this protocol.  Distribution of this memo is unlimited.

Abstract

   This memo defines a 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 monitoring
   selectable performance metrics and statistics derived from the
   monitoring of network packets and sub-application level transactions.
   The metrics can be defined through reference to existing IETF, ITU,
   and other standards organizations' documents.  The monitoring covers
   both passive and active traffic generation sources.

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.  Overview

   This document continues the architecture created in the RMON2-MIB
   [RFC2021] by providing a major feature upgrade, primarily by
   providing new metrics and studies to assist in the analysis of
   performance for sub-application transaction flows in the network, in
   direct relationship to the transport of application layer protocols.

   Performance-monitoring agents have been widely used to analyze the
   parameters and metrics related to the perceived performance of
   distributed applications and services in networks.  The metrics
   collected by these agents have ranged from basic response time to a

   combination of metrics related to the loss and re-transmission of
   datagrams and PDUs.  Although the metrics are becoming more useful in
   the implementation of service-level monitoring and troubleshooting
   tools, the lack of a standard method to report these has limited the
   deployment to very specific customer needs and areas.
