MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"This table will contain entries associated with an
apmReportControlEntry that consitute a current 'snapshot'
of the metrics being collected in association with
a set of TPM-related application transactions.
This table contains all sub-flow metrics for transactions
that have been started but have not yet finished (i.e.,
current) and a history of those that have finished (i.e.,
completed). It may not always be obvious from the context
whether a transaction is currently in-progress or has
been completed. Therefore, the completion status of a
transaction is indicated by the value of
the tpmCurReportCompletion object."
::= { tpmReports 3 }
tpmCurReportEntry OBJECT-TYPE
SYNTAX TpmCurReportEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"A conceptual row in the tpmCurReportTable.
The tpmAggrReportControlIndex value in the index identifies
the tpmAggrReportCntrlEntry on whose behalf this entry was
created. The tpmCurReportAppLocalIndex value in the
index identifies the application protocol that is being
reported. The protocolDirLocalIndex value in the
index identifies the network layer protocol
of the tpmAggrReportServerAddress. When the associated
tpmAggrReportCntrlAggrType value is
equal to applications(4), this value will equal 0.
The tpmCurReportServerAddress value in the
index identifies the network layer address of the
server in traffic flows aggregated in this entry.
The tpmCurReportCurrentApmNameClientID value in the
index identifies the network layer address of the
client in traffic flows aggregated in this entry.
The tpmCurReportCurrentMetricIndex value in the
index identifies the transported application protocol
of the traffic flows aggregated in this entry.
Note that the order of protocolDirLocalIndex variables is
the opposite of that in the RMON2 MIB (application.network
instead of network.application); the report entries are
sorted by application first, server second, and client third.
The tpmCurReportCntrIndex value in the index identifies
the tpmAggrReportCntrlEntry on whose behalf this entry was
created. The tpmCurReportMetricIndex value in the index
identifies the metric and protocol of the
tpmCurReportServerAddress, via the tpmTransMetricDir
table.
An example of the indexing of this table is
tpmCurReportStatisticN.3.34.262.18.4.128.2.6.6.3256521.29667"

the current round-trip time for a DNS query. For
other transaction types, this will represent the

the current throughput of an FTP transaction."

DESCRIPTION
"The status of this transaction. It is not always obvious
from context whether a transaction is ongoing or
completed. E.g., an ftp-GET transaction may last several
minutes or hours, and a value found in the
tpmCurReportMetricValue object lists to observed throughput
for the transaction up to this point in time. The value
of the tpmCurReportCompletion indicates whether the
transaction has been completed."
::= { tpmCurReportEntry 7 }
tpmCurReportSize OBJECT-TYPE
SYNTAX Unsigned32
MAX-ACCESS read-write
STATUS current
DESCRIPTION
"The maximum number of completed transactions desired to be
retained in the tpmCurReportTable. If the agent doesn't have
enough resources to retain this many, it will retain as many
as possible. Regardless of this value, the agent must
attempt to keep records for all current transactions it is
monitoring.
The agent should consider this value to give a hint as to
how many transactions to save. This is not a hard limit,
just a hint to a maximum value of interest. If this value is
reduced by the management station, the agent can take note,
it may free some records, or it may do nothing.
The value of this object must persist across reboots."

that data only from transactions associated with a
flagged application is included.

APM-MIB but adds the tpmTransMetricIndex to identify the
sub-application transaction and metric pair."

David Craver, Joseph Maixner, and John Metzger of Hifn, Inc. The
authors also gratefully acknowledge the beneficial discussions they
have had with Carter Bullard of QoSient, LLC. The tpmMetricDefTable
was taken from Andy Bierman's performance management capabilities
document, which was proposed early on in the RMON WG during the
formation of the TPM and APM MIB work. Finally, this MIB module
draws heavily from the work of Steve Waldbusser and his APM-MIB
[RFC3729].
6. Security Considerations
This MIB relates to a system that provides a passive monitoring capability of a broadcast subnet, a switched subnet, or point-to- point subnets. As such, it collects information relating to network layer addresses and traffic statistics relating to conversations and to application-level activities. These statistics could be deemed sensitive in certain networking environments. There are a number of management objects defined in this MIB module with a MAX-ACCESS clause of read-write and/or read-create. Such objects may be considered sensitive or vulnerable in some network environments. The support for SET operations in a non-secure environment without proper protection can have a negative effect on network operations. These are the tables and objects and their sensitivity/vulnerability: + The tpmTransMetricDirConfig object describes and configures the probe's support for a given performance metric in relation to a specified transaction and application. The agent creates entries in this table for all metric and transaction combinations that it can generate, and this object controls the on/off switch for this capability. If certain statistics for a supported transaction are deemed sensitive, then access to SET operations on this object should be protected. + The tpmAggrReportCntrlDataSource sets the interface on which the network addresses and conversational and application-level statistics will be collected. + The tpmAggrReportCntrlAggrType object controls the level of data aggregation implemented in the report tables. For example, this object could be set to allow client-level information to be exposed. In order to implement this MIB module, an agent must make certain management information available about protocols and network addresses used within a managed system, which may be considered sensitive in some network environments. Therefore some of the readable objects in this MIB module (i.e., objects with a MAX-ACCESS other than not-accessible) may be considered sensitive or vulnerable in some network environments. It is thus important to control even GET and/or NOTIFY access to these objects and possibly to even encrypt the values of these objects when sending them over the network via SNMP. These are the tables and objects and their sensitivity/vulnerability:
+ The tpmAggrReportTable contains the statistical studies which
the probe was configured to generate. These tables contain the
historical, aggregated data providing information on the network
address and traffic statistics related to their conversations.
+ The tpmCurReportTable contains information on current
transaction flows. This table provides a view of the current
activity on a subnet or a client machine.
SNMP versions prior to SNMPv3 did not include adequate security.
Even if the network itself is secure (for example by using IPSec),
even then, there is no control as to who on the secure network is
allowed to access and GET/SET (read/change/create/delete) the objects
in this MIB module.
It is RECOMMENDED that implementers consider the security features as
provided by the SNMPv3 framework (see [RFC3410], section 8),
including full support for the SNMPv3 cryptographic mechanisms (for
authentication and privacy).
Further, deployment of SNMP versions prior to SNMPv3 is NOT
RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to
enable cryptographic security. It is then a customer/operator
responsibility to ensure that the SNMP entity giving access to an
instance of this MIB module is properly configured to give access to
the objects only to those principals (users) that have legitimate
rights to indeed GET or SET (change/create/delete) them.
