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 objects for configuring autonomous report generation on any device that supports MIBs containing counter and gauge objects for performance monitoring. This allows a management station to instruct a device to build off-line reports to be collected asynchronously by the management station. Further, this REPORT-MIB can be configured in a proxy configuration where the report generation is performed on a device in close network proximity to the device containing the referenced counter objects. Hence, this capability allows network operators to reduce the SNMP polling traffic burden on Mobile Ad-Hoc and Disruption Tolerant Networks which is typical of SNMP performance management applications.

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 objects for configuring autonomous, off-line report generation for performance monitoring on any device supporting MIBs containing variables that resolve to type Integer32 (i.e., Integer32, Counter, Gauge, or TimeTicks). This REPORT-MIB allows for the report generation to occur on the same device as containing the referenced counter object or on a device in close network proximity to the device with the referenced counter object. This should be useful to devices or networks where efficient use of bandwidth is of concern or where intermittent connectivity is common. Hence, the REPORT-MIB is useful for devices managed over some Mobile Ad-Hoc Networks (MANETs) or Disruption Tolerant Networks (DTNs).
The REPORT-MIB offers three types of off-line reporting. One type offering reports which present statistical analysis of the objects being tracked; found within the reportStatsGroup. The second type offering a means to collect sampled data related to defined MIB objects. This second type of reporting is contained in the reportSampledGroup. The third offering reports which present (collect) raw data values and their time of change from the objects being tracked; found within the reportHistoryGroup.
For statistical reporting, the REPORT-MIB borrows from the RMON [RFC1757] (Waldbusser, S., “Remote Network Monitoring Management Information Base,” February 1995.) ReportsControl and Reports Tables. Here the reportStatsCapabilitiesGroup defines the capabilities of the device with respect performance monitoring and statistical analysis. Some analysis is hard-coded into the definition of the reportStatsDataGroup while the device can also advertise extended statistical reporting via the reportMetricExtDefTable. The reportsControlTable specifies the report metrics, the Object ID to monitor and other aspects of the statistical report development and storage.
For the collection of sampled data, the REPORT-MIB draws directly from the usrHistoryGroup from RMON 2 [RFC2021] (Waldbusser, S., “Remote Network Monitoring Management Information Base Version 2 using SMIv2,” January 1997.). Here the reportSampledControlTable allows the user to define aspects of the report for sampled data, including the number of MIB objects to be sampled and the nature of the sampling frequency and overall report duration. This group uses the notion of buckets, which contained sampled data from a set of identified MIB objects sampled at the same time point. The report consists of the buckets each containing sets of sampled data from the same MIB objects but at differing sampling times. The reportSampledObjectTable allows the user to identify the multiple MIB objects to be sampled. The reportSampledDataTable contains the storage of the reported sampled data contained within buckets, one for each sampling instance.
For the collection of raw data, the REPORT-MIB contains a reportHistoryGroup comprised of the reportHistoryControlTable for control of historical data reports and the reportHistoryDataTable for the storage of the historical reports.
Various compliance groups which allow for development of raw data collection reports, collection of sampled data reports or only statistical data reports, or all combinations.

For a detailed overview of the documents that describe the current Internet-Standard Management Framework, please refer to section 7 of RFC 3410 [RFC3410] (Case, J., Mundy, R., Partain, D., and B. Stewart, “Introduction and Applicability Statements for Internet-Standard Management Framework,” December 2002.).
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] (McCloghrie, K., Ed., Perkins, D., Ed., and J. Schoenwaelder, Ed., “Structure of Management Information Version 2 (SMIv2),” April 1999.), STD 58, RFC 2579 [RFC2579] (McCloghrie, K., Ed., Perkins, D., Ed., and J. Schoenwaelder, Ed., “Textual Conventions for SMIv2,” April 1999.) and STD 58, RFC 2580 [RFC2580] (McCloghrie, K., Perkins, D., and J. Schoenwaelder, “Conformance Statements for SMIv2,” April 1999.).

The Reporting MIB references performance objects in other MIBs and generates offline performance reports on those referenced objects. The REPORT-MIB can be coincident with the other MIB or can reside on another device in close network proximity to the device containing the referenced performance related object.
| TOC |
This section describes the management model for the Reporting MIB process. First, the model for the reportStatsGroup is presented. Then the model for the reportSampledGroup and the reportHistoryGroup are presented.
Figure 1 illustrates a potential use of the REPORT-MIB for the generation of off-line, remotely generated reports. The management station on the left hand side of the illustration instructs the remote device to create reports through manipulation of the ReportCntrl Objects in the REPORT-MIB resident on the remote device. The reports instruct the device to monitor the status of specified counters (on other MIBs and potentially on other devices in close network proximity) periodically and to generate a set of metrics describing the temporal behavior of those counter values. The reports are stored locally until the management station decides to pull them off the device. The figure shows a case where the REPORT-MIB generates a notification that Report_2 has completed, prompting the management station to pull Report_2 from the device.

Figure 1: REPORT-MIB front-end report generation process.
The REPORT-MIB's reportStatsGroup defines specifically a set of metrics which are computed within all reports. It also allows for the specification of metric extensions which are local to the specific implementation of the REPORT-MIB. These are identified in the reportStatsCapabilitiesGroup metricExtension Table.
Each metric has an associated Object ID of type counter associated with it. The control table specifies a report interval and a bin interval. The report interval is an integral multiple of the bin interval. For each bin interval, the device identifies the change in the counter value over the bin interval (called x_i) and then computes the associated metric, e.g., sum, sum of the square, etc, over the set {x_i}. It maintains the sum of these computations within the metric objects in the 'reportStatsDataTable'. Once the report interval is complete, the management station has enough information to compute a set of interesting and useful statistics.
The computational model of the reportStatsGroup of the REPORT-MIB is illustrated in the figure below. The important controls are a) the contrlInterval, b) the cntrlBinInterval, c) the specific counterObjectId, and d) the metric. In the figure x_i represents the ith value of the counter change, i.e., x_i = counterValue(t_i+1) - counterValue(t_i). The metrics reported are then computed from the set (x_i). Three examples are identified in the figure, e.g., StatSumX, StatSumSq and StatMaxX. Other existing and potential metrics are discussed below.

where t_i - t_i-1 = cntrlBinInterval
n = cntrlInterval / cntrlBinInterval
StatSumX = Sum(x_i) from i=0, ..., n-1
StatSumSq = Sum((x_i)^2) from i=0, ..., n-1
StatMaxX = Max(x_i) for i=0, ..., n-1
Figure 2: REPORT-MIB statistical analysis computation process.
This capability then allows for the computation of various significant statistics related to the behavior of the referenced object.
These are accessible from the statistical datum provided by this MIB module. Other statistics are derivable including, e.g., the slope of a least-squares fit to the rate of change of the referenced object. These are described below.
The REPORT-MIB also provides for the collection of sampled data instead of statistical data. It does this by importing (copying) the usrHistory group from RMON2 [RFC2021] (Waldbusser, S., “Remote Network Monitoring Management Information Base Version 2 using SMIv2,” January 1997.) which allows for the generation of reports collecting the sampled object values binned for the purpose of aggregation and efficiency of collection. These are defined within the reportSampledGroup. The model used for this type of report generation is based upon three tables. The reportSampledControlTable defines aspects of the report generation related to duration of the reporting interval, the bin (or bucket) sizes for the report, and the number of object values collected for each bucket. The reportUsrHistoryObjectTable identifies the specific MIB objects whose values and binned within the report. And the reportSampledDataTable contains the binned data values collected for the report.
The REPORT-MIB also provides for the collection of historical data instead of statistical or sampled data. It does this by defining the reportHistoryControlTable for the control of the historical reports and the reportHistoryDataTable for the storage of the historical reports.

The following definitions apply throughout this document:

This section presents the structure of the REPORT-MIB module. The objects are arranged into the following groups:
| TOC |
The textual conventions used in the REPORT-MIB are as follows. The RowStatus textual convention is imported from RFC 2579 [RFC2579] (McCloghrie, K., Ed., Perkins, D., Ed., and J. Schoenwaelder, Ed., “Textual Conventions for SMIv2,” April 1999.).
| TOC |
The REPORT-MIB Statistics Group contains objects which allows for the generation of statistical analysis reports. For example, this group can be exercised to generate the mean and variance of the referenced counter object. The Statistics Group is composed of:
As and example of how the metrics are to be computed within the REPORT-MIB, consider the standard metric object 'reportStatsDataStatSumX'. For each bin interval defined by the object reportCntrlReportsBinInterval, the change in the value of the counter pointed to by the Object ID reportCntrlReportsPriObjID is calculated. Then this (delta) value is added to the current value of the value contained in the object 'reportStatsDataStatSumX'. Then, if interested in computing the average change in this object (sampled each bin interval) for the duration of the report, the management station simply divides reportStatsDataStatSumX by reportStatsDataStatN. Although this is a trivial example because the value of reportAggrReportStatSumX is simple the difference in the counter reportCntrolReportsPriObjID at the start and the end of the total report interval, the other metrics defined are not as trivial.
The objects 'reportStatsDataOverflowStatSumX' and 'reportStatsDataHCSumX' are borrowed from RMON [RFC2021] (Waldbusser, S., “Remote Network Monitoring Management Information Base Version 2 using SMIv2,” January 1997.) and exist to handle integer overflow situations where, e.g., 'reportStatsDataStatSumX' overruns its maximum vary numerous times.
Computation of the least-square fit of the data collected for a report can be accomplished. (NOTE: describe this capability here.)
| TOC |
The Sampled Group contains tables which allows for the development of reports based upon sampling the referenced counter objects at specified intervals. The development of this group within the REPORT-MIB follows exactly the User History group from the RMON 2 MIB [RFC2021] (Waldbusser, S., “Remote Network Monitoring Management Information Base Version 2 using SMIv2,” January 1997.). The Sampled Group is composed of:
| TOC |
The History Group contains tables which capture information on change events for he referenced objects. Depending upon the referenced objects, this could force the generation of large amounts of data. Care should be exercised when considering the use of this capability.
| TOC |
The Notifications Sub-tree contains the list of notifications supported within the REPORT-MIB and their intended purpose or utility. This group is currently empty.
| TOC |
[TODO]: The text of this section specifies the relationship of the MIB modules contained in this document to other standards, particularly to standards containing other MIB modules. Definitions imported from other MIB modules and other MIB modules that SHOULD be implemented in conjunction with the MIB module contained within this document are identified in this section.
| TOC |
The 'system' group in the SNMPv2-MIB [RFC3418] (Presuhn, R., “Management Information Base (MIB) for the Simple Network Management Protocol (SNMP),” December 2002.) is defined as being mandatory for all systems, and the objects apply to the entity as a whole. The 'system' group provides identification of the management entity and certain other system-wide data. The REPORT-MIB does not duplicate those objects.
| TOC |
The REPORT-MIB is closely related in many aspects to the RMON2-MIB [RFC2021] (Waldbusser, S., “Remote Network Monitoring Management Information Base Version 2 using SMIv2,” January 1997.). Specifically, the reportSampledGroup is a direct copy of the RMON2 User History Group, with the names changed to comply with the naming conventions within the REPORT-MIB. Further, the design and use of the control tables within the REPORT-MIB draw exactly from the definition of this table structures in the earlier RMON MIBs.
| TOC |
The REPORT-MIB pulled the reportStatsGroup directory from the TPM-MIB [RFC4150] (Dietz, R. and R. Cole, “Transport Performance Metrics MIB,” August 2005.). The table structures and the choice of statistics draws directly from the earlier TPM-MIB developed within the RMON Working Group.

[TODO]: Citations are not permitted within a MIB module, but any module mentioned in an IMPORTS clause or document mentioned in a REFERENCE clause is a Normative reference, and must be cited someplace within the narrative sections. If there are imported items in the MIB module, such as Textual Conventions, that are not already cited, they can be cited in text here. Since relationships to other MIB modules should be described in the narrative text, this section is typically used to cite modules from which Textual Conventions are imported.
The following REPORT-MIB module IMPORTS objects from SNMPv2-SMI [RFC2578] (McCloghrie, K., Ed., Perkins, D., Ed., and J. Schoenwaelder, Ed., “Structure of Management Information Version 2 (SMIv2),” April 1999.), SNMPv2-TC [RFC2579] (McCloghrie, K., Ed., Perkins, D., Ed., and J. Schoenwaelder, Ed., “Textual Conventions for SMIv2,” April 1999.), SNMPv2-CONF [RFC2580] (McCloghrie, K., Perkins, D., and J. Schoenwaelder, “Conformance Statements for SMIv2,” April 1999.), and IF-MIB [RFC2863] (McCloghrie, K. and F. Kastenholz, “The Interfaces Group MIB,” June 2000.)

-- of a row in this table will cause one or more associated instances in
-- the reportSampledObjectTable to be created. The user specifies the
-- number of bucket elements (rows in the reportSampledObjectTable)
-- requested, as well as the number of buckets requested.
--
-- The reportSampledObjectTable is a 2-d read-write table.
-- Each row configures a single MIB instance to be collected.
-- All rows with the same major index constitute a bucket-group.
--
-- The reportSampledTable is a 3-d read-only table containing
-- the data of associated reportSampledControlEntries. Each
-- entry represents the value of a single MIB instance
-- during a specific sampling interval (or the rate of
-- change during the interval).
--
-- A sample value is stored in two objects - an absolute value and
-- a status object. This allows numbers from -(2G-1) to +4G to be
-- stored. The status object also indicates whether a sample is
-- valid. This allows data collection to continue if periodic
-- retrieval of a particular instance fails for any reason.
--
-- Row Creation Order Relationships
--
-- The static nature of the reportSampledObjectTable creates
-- some row creation/modification issues. The rows in this
-- table need to be set before the associated
-- reportSampledControlEntry can be activated.
--
-- Note that the reportSampledObject entries associated with a
-- particular reportSampledControlEntry are not required to
-- be active before the control entry is activated. However,
-- the reportSampled data entries associated with an inactive
-- reportSampledObject entry will be inactive (i.e.
-- reportSampledValStatus == valueNotAvailable).

When the associated reportSampledControlBucketsRequested

DESCRIPTION
"The object identifier of the particular variable to be

Only variables that resolve to an ASN.1 primitive type of

Because SNMP access control is articulated entirely in terms
of the contents of MIB views, no access control mechanism
exists that can restrict the value of this object to identify
only those objects that exist in a particular MIB view.
Because there is thus no acceptable means of restricting the
read access that could be obtained through the user history
mechanism, the probe must only grant write access to this
object in those views that have read access to all objects on
the probe.
During a set operation, if the supplied variable name is not
available in the selected MIB view, a badValue error must be

[TODO] Each specification that defines one or more MIB modules MUST contain a section that discusses security considerations relevant to those modules. This section MUST be patterned after the latest approved template (available at http://www.ops.ietf.org/mib-security.html). Remember that the objective is not to blindly copy text from the template, but rather to think and evaluate the risks/vulnerabilities and then state/document the result of this evaluation.
[TODO] if you have any read-write and/or read-create objects, please include the following boilerplate paragraph.
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:
[TODO] else if there are no read-write objects in your MIB module, use the following boilerplate paragraph.
There are no management objects defined in this MIB module that have a MAX-ACCESS clause of read-write and/or read-create. So, if this MIB module is implemented correctly, then there is no risk that an intruder can alter or create any management objects of this MIB module via direct SNMP SET operations.
[TODO] if you have any sensitive readable objects, please include the following boilerplate paragraph.
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:
[TODO] discuss what security the protocol used to carry the information should have. The following three boilerplate paragraphs should not be changed without very good reason. Changes will almost certainly require justification during IESG review.
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] (Case, J., Mundy, R., Partain, D., and B. Stewart, “Introduction and Applicability Statements for Internet-Standard Management Framework,” December 2002.), 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.

[TODO] In order to comply with IESG policy as set forth in http://www.ietf.org/ID-Checklist.html, every Internet-Draft that is submitted to the IESG for publication MUST contain an IANA Considerations section. The requirements for this section vary depending what actions are required of the IANA. see RFC4181 section 3.5 for more information on writing an IANA clause for a MIB module document.
[TODO] select an option and provide the necessary details.
Option #1:
The MIB module in this document uses the following IANA-assigned
OBJECT IDENTIFIER values recorded in the SMI Numbers registry:
Descriptor OBJECT IDENTIFIER value
---------- -----------------------
sampleMIB { mib-2 XXX }
Option #2:
Editor's Note (to be removed prior to publication): the IANA is requested to assign a value for "XXX" under the 'mib-2' sub-tree and to record the assignment in the SMI Numbers registry. When the assignment has been made, the RFC Editor is asked to replace "XXX" (here and in the MIB module) with the assigned value and to remove this note.
Note well: prior to official assignment by the IANA, a draft document MUST use placeholders (such as "XXX" above) rather than actual numbers. See RFC4181 Section 4.5 for an example of how this is done in a draft MIB module.
Option #3:
This memo includes no request to IANA.

We would like to thank Bert Wijnen and Andy Bierman for pointing out the existence of the usrHistory group within RMON2 and in answering our numerous questions on the usrHistory group. Further, we wish to thank U. Herberg for his forcing additions to this MIB through his thoughtful consideration of performance monitoring requirements for other MIBs, e.g., NHDP and OLSR MIBs.
