Definition of Managed Objects for Performance Reporting
draft-ietf-manet-report-mib-03
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-SAMPLED-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 Internet-Draft is submitted in full conformance with the provisions of BCP 78 and BCP 79.

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-SAMPLED-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-SAMPLED-MIB is useful for devices managed over some Mobile Ad-Hoc Networks (MANETs) or Disruption Tolerant Networks (DTNs).
This version of the REPORT-SAMPLED-MIB offers one type of off-line reporting. The MIB offers a means to collect sampled data related to defined MIB objects. This type of reporting is contained in the reportSampledGroup. Other types of report data are possible, including statistical data and historical data. However, it was felt wise to focus on a more limited scope off-line reporting capability and gain experimental use and application prior to expending energy developing a more extensive capability.
For the collection of sampled data, the REPORT-SAMPLED-MIB draws directly from the usrHistoryGroup from RMON 2 [RFC2021] through application of the 'AUGMENTS' clause. . 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 contain 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 selected MIB objects but at the specific 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 bucket for each time sampling instance.
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].
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119].
The REPORT-SAMPLED-MIB references performance objects in other MIBs (and in other devices) and generates off-line performance reports related to those referenced objects. The REPORT-SAMPLED-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.
This section describes the management model for the REPORT-SAMPLED-MIB process.
Figure 1 illustrates a potential use of the REPORT-SAMPLED-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-SAMPLED-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. The reports are stored locally until the management station decides to pull them off the device. The figure shows a case where the REPORT-SAMPLED-MIB generates a notification that Report_2 has completed, prompting the management station to pull Report_2 from the device.

Figure 1: REPORT-SAMPLED-MIB front-end report generation process.
This version of the REPORT-SAMPLED-MIB provides for the collection of sampled data instead of statistical data. It does this by augmenting the usrHistory group from RMON2 [RFC2021] 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 are binned within the report. And the reportSampledDataTable contains the binned data values collected for the report.
The following definitions apply throughout this document:
This section presents the structure of the REPORT-SAMPLED-MIB module. The objects are arranged into the following groups:
No textual conventions are used in the REPORT-SAMPLED-MIB.
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-SAMPLED-MIB which augments the User History group from the RMON 2 MIB [RFC2021]. The Sampled Group is composed of:
The Notifications Sub-tree contains the list of notifications supported within the REPORT-SAMPLED-MIB and their intended purpose or utility. The single notification defined within this MIB module is the 'reportSampledNewDataReport'. This notification is sent by the agent upon completion of a given report on the device. The notification contains the following objects: 'usrHistoryControlOwner', the entity that configured this report entry, and the 'reportSampledReportIndex', the index of the data table for this report. Collectively, these objects allow the management application to pull the completed report from the agent.
The REPORT-SAMPLED-MIB module contains a number of tables which record data related to:
The REPORT-SAMPLED-MIB module's tables are indexed via the following constructs:
These tables and their indexing are:
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.
The 'system' group in the SNMPv2-MIB [RFC3418] 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-SAMPLED-MIB does not duplicate those objects.
The REPORT-SAMPLED-MIB is closely related to the RMON2-MIB [RFC2021] usrHistoryGroup. 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-SAMPLED-MIB. Further, the design and use of the control tables within the REPORT-SAMPLED-MIB draw exactly from the definition of these table structures in the earlier RMON MIBs through the use of the 'AUGMENTS' clause within the 'reportSampledControlTable' and the 'reportSampledTable' in this MIB module.
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. Therefore, the imported items in this MIB module, such as Textual Conventions, that are not already cited, are cited in this section. Since relationships to other MIB modules should be described in the narrative text, this section will cite modules from which Textual Conventions are imported.
The REPORT-SAMPLED-MIB module IMPORTS objects from SNMPv2-SMI [RFC2578], SNMPv2-TC [RFC2579], SNMPv2-CONF [RFC2580], IF-MIB [RFC2863], and INET-ADDRESS-MIB [RFC4001]. Significantly, the REPORT-SAMPLED-MIB module also IMPORTS objects from the RMON2-MIB module [RFC2021].

END
This REPORT-SAMPLED-MIB defines a capability where the local device may poll other remote devices to collect performance data accessible through other MIB modules on the remote devices. These capabilities defined within the REPORT-SAMPLED-MIB are control-able by a network management application through SNMP. As such, a network management application could potentially use the REPORT-SAMPLED-MIB as a mechanism to implement a Distributed Denial-of-Service (DDoS) attack against remote devices. Care should be taken to secure access to the REPORT-SAMPLED-MIB agent. Specifically, access control mechanisms and authentication mechanisms (via SNMPv3) should always be used for SNMP SET operations. Further, some objects may contain data deemed sensitive and authentication and encryption mechanisms (via SNMPv3) should be used for SNMP GET operations.
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:
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.
This document describes objects for configuring parameters of the remote report generation process on a router or close device. This MIB module, denoted REPORT-SAMPLED-MIB, also reports performance information and notifications. The REPORT-SAMPLED-MIB provides for the remote control, collection and notification of performance reports on devices. As such, it eliminates the need for periodic polling for counters from remote management stations as a means for generating performance reports. This is hoped to greatly reduce management overhead on the MANET. This sections provides some examples of how this MIB module can be used in MANET network deployments. A fuller discussion of MANET network management use cases and challenges will be provided elsewhere.
