          DESCRIPTION
             "This module defines extensions to the RMON2-MIB module
             for the collection of Performance Metrics related to
             application traffic in a network.  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.

             In order to maintain the RMON 'look-and-feel', some of
             the text from the RMON2 [RFC2021] and HC-RMON [RFC3273]
             MIBs by Steve Waldbusser have been used in this MIB module.

           "This table is used to describe and link sets of
           performance metrics and protocols to an entry in
           the application directory.  This table, with the
           tpmMetricDefTable, describes the capability of
           the agent to collection sub-application level
           data related to each entry in the
           apmAppDirectoryTable.

           This table lists the protocol transactions and their
           corresponding performance metrics that this agent
           has the capability to compute and collect, for the specified
           application.  There is one entry in this table for each such
           application, protocol transaction, and metric combination
           supported by this agent.  The entries in this
           table represent the metrics that are collected for each
           protocol transaction that comprise the application.
           The agent should boot up with this table pre-configured
           with those combinations of applications, protocol
           transactions, and metrics that it knows about and wishes to
Top   ToC   RFC4150 - Page 16
           monitor.  Implementations must populate the table with all
           possible application, protocol transaction, and metric
           combinations and have the default configuration objects
           set to supportedOff(2).  This table does not support the
           creation of new combinations by the management application.

           The deletion of an entry in the apmAppDirectoryTable will
           cause the removal of entries from this table.  These entries
           must be removed because the appLocalIndex value will no
           longer be visible in the apmAppDirectoryTable.  When an entry
           is created in the apmAppDirectoryTable and the agent has the
           ability to support metrics for these protocol transactions,
           the appropriate entries must be made in the

Top   ToC   RFC4150 - Page 18
           creates entries in this table for all metric
           and transaction combinations that it can generate.  Because
           the probe will only populate this table with supported
           entries, and the table cannot have entries added, the

           this object will not change to notSupported(1) due to a
           change to supportedOff(2) in the tpmMetricDir table.

           If the value of this object is notSupported(1), the probe
           will not perform computations for this performance metric and

           metric for the specified protocol, but is configured
           not to perform the computations for this performance
           metric and protocol for the application for any
           interfaces.  Whenever this value changes from

           created.

           The tpmAggrReportIndex value in the index identifies which
           report (in the series of reports) this entry is a part of.

           The tpmAggrReportAppLocalIndex value in the index identifies
           the application protocol that is being reported.

           The tpmTransMetricIndex value in the index identifies
           the transaction protocol-metric pair for the traffic flows
           aggregated in this entry.

           The protocolDirLocalIndex value in the index identifies the
           network layer protocol of the tpmAggrReportServerAddress.
           When the associated tpmAggrReportCntrlAggrType value is equal
           to applications(4) or clients(2), this value will equal 0.

           The tpmAggrReportServerAddress value in the index identifies
           the network layer address of the server in traffic flows
           aggregated in this entry.

           The tpmAggrReportApmNameClientID value in the index
           identifies the client in traffic flows aggregated in this
           entry.  If the associated tpmAggrReportCntrlAggrType is equal
           to applications(4) or servers(3), then this object will be
           set to 0.

           An example of the indexing of this entry is
           tpmAggrReportStatN.3.15.34.262.18.4.128.2.6.7.3256521"

           This is represented as an octet string with specific
           semantics and length as identified by the
           protocolDirLocalIndex component of the index.

           Because this object is an index variable, it is encoded in
           the index according to the index encoding rules.  For
           example, if the protocolDirLocalIndex indicates an
           encapsulation of IPv4, this object is encoded as a length
           octet of 4, followed by the 4 octets of the IPv4 address,
           in network byte order.

           If the associated tpmAggrReportCntrlAggrType is equal to
           application(4) or client(2), then this object will be a null
           string and will be encoded simply as a length octet of 0."
