Active Probes for Performance Monitoring (APPM) Draft: <draft-cole-appm-00.txt> posted to DISMAN WG list Authors: Cole, R., Kalbfleisch, C. and D. Romascanu Outline: • Introduction • Goals and Objectives • Architecture • Previous and Related Work • Configuration Issues • Implementation Issues • Security Issues • Next Steps
Active Probes for Performance Monitoring (APPM) Goals and Objectives: • Define a complimentary, ‘active’ probe capability • Identifies the utility of active probes, e.g., • troubleshooting paths • circuit pre-test and turn-up • fault management • baselining enhancements • end-to-end capacity management • Service Level Agreement (SLA) monitoring • Active versus Passive Monitoring • control over the sampling • control over probe characteristics • traffic generation
Active Probes for Performance Monitoring (APPM) Architectural Issues: • Network layer and application layer • Configuration control • Relationship to fault management and data reduction • Standard instrumentation, data reduction and reporting (e.g., via RMON methods) • Deployment considerations • Relationship to passive probes • Security of active probe methods
Active Probes for Performance Monitoring (APPM) Related Work: • IPPM WG • set of performance metrics, sampling methods, .. • DISMAN WG • active probes for fault management, some performance info, ... • RMON WG • passive monitoring, application monitoring (work in prog), reporting, ... • ApplMIB WG • application and service mgmt (fault, configuration and performance), ... • Others to be discussed: • RTFM, BMWG, frnetMIB
Active Probes for Performance Monitoring (APPM) Configuration Issues: • Sampling methods • IPPM work on sampling methodologies • Probe configurations • static, sampling control, data config, path config, ... • Statistics, Reports and Historical Data • data reduction, standard reporting methods, raw data, .. • Indexing to Other Measurements • correlation of end-to-end service level monitoring to component level monitors
Active Probes for Performance Monitoring (APPM) Implementation Issues: • Requirements on Implementations • bounds on packet generation, clock resolution, .. • Error Analysis Statements • statement on the accuracy of the measurement process and results • Compliance Tests • assessing the conformance of a probe
Active Probes for Performance Monitoring (APPM) Potential Work Items: • Develop a framework/architecture document • and possibly a separate security document • Develop a MIB for active probes and others for usage of the MIB • Define a set of transport level metrics (e.g., IPPM) and a set of corresponding probes • Define a set of application level metrics and probes
