Remote Network Monitoring (rmonmib) ----------------------------------- Charter Last Modified: 2006-03-24 Current Status: Active Working Group Chair(s): Andy Bierman Operations and Management Area Director(s): Dan Romascanu David Kessens Operations and Management Area Advisor: David Kessens Technical Advisor(s): Steven Waldbusser Matthew Zekauskas Mailing Lists: General Discussion:rmonmib@ietf.org To Subscribe: http://www.ietf.org/mailman/listinfo/rmonmib Archive: http://www.ietf.org/mail-archive/web/rmonmib/index.html Description of Working Group: Steve Waldbusser is TA for SNMP/MIB related matters Matt Zekauskas is TA for Transport Retaled matters The RMON MIB Working Group is chartered to define a set of managed objects for remote monitoring of networks. These objects will be the minimum necessary to provide the ability to monitor multiple network layers of traffic in remote networks; providing fault, configuration, and performance management, and will be consistent with the SNMP framework and existing SNMP standards. The following list of features for this RMON has been previously discussed in relation to existing RMON functionality and is included to focus these RMON activities. It is recognized that other issues may be considered and that certain of the following issues may not be part of the final specification(s): 1. Application Performance Measurement Monitoring support for the measurement and characterization of network application protocols, striving to measure an application user's experience as closely as possible. The RMON-2 MIB (RFC 2021) contains a protocol directory that will be used to identify applications for monitoring purposes. While it is important to measure the performance of computing and network resources, these measurements don't give an insight to the actual service delivered to end-users. This end-user experience is best measured by the response-time and availability of application transactions because users interact directly with applications. This working group will create extensions to the RMON-2 MIB that will allow Application Performance Measurements to be retrieved with SNMP, no matter which technology is used to perform the measurements. The goal of the working group is to provide a common framework and set of MIB objects, within the current RMON framework, for the identification and characterization of application responsiveness and availability, and the reporting of test results produced by such mechanisms. Common metrics and derived metrics will be characterized and reported in a manner consistent with the IP Performance Metrics Framework (RFC 2330). It is an explicit non-goal of the working group to select one or more mechanisms as the preferred or standard RMON application performance measurement mechanism. However, it is possible that one or more standard mechanisms will be developed in the future, after significant implementation experience has been gained by the working group. 2. Differentiated Services Statistics Collection Monitoring support for Differentiated Services (DS) statistics collection, for the purpose of DS codepoint usage analysis and possibly other statistics related to DS deployment and performance tuning. 3. Interface TopN Reporting It is often too slow or difficult to determine the busiest ports in devices such as high port-density switches, using existing RMON mechanisms. New monitoring support is needed for quickly determining the most congested (highest utilized) physical ports and links in an RMON-capable device with multiple interfaces. 4. TR-RMON MIB Advancement The Token Ring RMON MIB (RFC 1513) is ready for standards track advancement. An interoperability and deployment survey has already been completed, but the MIB must be updated in SMIv2 format before it can be advanced on the standards track. 5. Transport Performance Measurement There is a need for standardized means to collect and report selectable performance metrics and statistics derived from the monitoring of network packets and transport protocol states. The monitoring covers both passive and active traffic generation sources. Monitoring support for the these measurements can provide a drill-down capability to provide insight into the performance of the lower-level transactions which comprise the overall performance of a network application. The goal of the working group is to provide a common framework and set of MIB objects, within the current RMON framework, for the identification and characterization of transaction-level performance, and the reporting of test results produced by such mechanisms. Common metrics and derived statistics will be characterized and reported in a manner consistent with the IP Performance Metrics Framework (RFC 2330). 6. SMON MIB Advancement The SMON MIB (RFC 2613) is ready for standards track advancement. An interoperability and deployment survey will be completed, and submitted to the IESG. It is possible that minor enhancements and corrections to RFC 2613 will be made, based on the survey findings and working group input. 7. RMON-2 MIB Advancement The RMON-2 MIB (RFC 2021) is ready for standards track advancement. An interoperability and deployment survey will be completed, and submitted to the IESG. It is possible that minor enhancements and corrections to RFC 2021 will be made, based on the survey findings and working group input. 8. RMON PI Reference Advancement The RMON Protocol Identifiers Reference (RFC 2895) is ready for standards track advancement. An interoperability and deployment survey will be completed, and submitted to the IESG. It is possible that minor enhancements and corrections to RFC 2895 will be made, based on the survey findings and working group input. 9. Synthetic Sources for Performance Monitoring Mechanisms are needed for the remote control of synthetic packet sources and destinations, for the purpose of enhancing remote performance monitoring capabilities within IP networks and services. These mechanisms must utilize the RMON protocol directory for protocol encapsulation identification. Any interactions with the RMON Framework or dependencies on specific RMON MIB objects (if any) will be specified as well. 10. RMON Framework Documentation is needed which clarifies the remote network monitoring framework, and describes the inter-relationships and dependencies between the various RMON MIB modules. A conceptual model is needed to help administrators and developers better understand data sources, the protocol directory, and the existing RMON statistical collections. Undocumented 'RMON folklore', as well as the limitations and appropriate application of various implementation techniques will also be addressed. 11. Real-time Application QoS Monitoring MIB There is a need to extend the RMON framework to monitor end devices such as IP Phones, pagers, Instant Message Clients, Cell Phones, and PDA devices. An end-to-end user experience of the quality of service (QoS) and performance for such an application is a combination of device performance and transport network performance. Monitoring should be performed at the application layer that reflects a specific end user experience on a particular IP end point, reflecting specific transport network performance There is a need to extend the RMON framework to monitor end devices such as IP Phones, pagers, Instant Message Clients, Cell Phones, and PDA devices. An end-to-end user experience of the quality of service (QoS) and performance for such an application is a combination of device performance and transport network performance. Monitoring should be performed at the application layer that reflects a specific end user experience on a particular IP end point, reflecting specific transport network performance. This working group will extend the RMON Framework to allow Real-time Application QoS information of these types of end devices to be retrieved with SNMP, independent of the technology used to perform the measurements. The WG will define a common framework and set of MIB objects, within the current RMON framework, for the identification and characterization of application QoS parameters, and the reporting of the on-going measurement reports produced by these mechanisms. Common metrics and derived metrics will be characterized and reported in a manner consistent with the IP Performance Metrics Framework (RFC 2330). The WG will also define a set of RAQMON Application level QoS PDUs to have common formats of reporting statistics between a RAQMON Data Source and a RAQMON Report Collector. These Common RAQMON PDUs will be transported over existing protocols, such as RTCP or SNMP. The measurement methodology is out of the scope of the RAQMON work and will be in conformance with the IPPM WG recommendations, and also may take into account considerations from application-specific (IM and telephony) WGs as needed. This WG will consider the cases for transport of RAQMON PDUs, including how RTCP might be used and still meet security/privacy goals. Security aspects related to RAQMON reports will be cognizant of privacy and anonymity issues while being responsive to the needs of measurement applications.
