INTRODUCTION

The Cisco® Performance Visibility Manager is an enterprise-level, centralized network management tool that enhances the Cisco Network Analysis Module (NAM) for Cisco Catalyst® 6500 Series switches, 7600 Series routers and Branch Routers series. Cisco PVM provides a centralized and integrated End-to-End (E2E) network view, by aggregating and correlating information from multiple NAMs that are strategically deployed in the network. Cisco PVM is highly scalable, and uses a highly extensible architecture which makes it easy to add additional Cisco device instrumentation like Netflow, IP SLA agent and NBAR in future releases.

Cisco PVM is a feature-rich network management tool.

The following features are currently available in PVM 1.0.

Data Collection and Traffic Analysis

Cisco PVM collects traffic statistics from multiple NAMs and aggregates the information based on user-defined datasource groups to provide you an intuitive and integrated end-to-end view of your network, allowing you to quickly pinpoint trouble spots.

Traffic Analysis including Top-N Analysis

Cisco PVM’s Traffic Analysis, including Top-N Analysis, provides unparalleled visibility into the traffic running in your network. By aggregating and analyzing traffic in real time, you can detect and troubleshoot problems in the network before the users are adversely affected. PVM has the capability to aggregate real-time information for up to 7 days. You can traverse back in time and troubleshoot a client problem.

ART Monitoring

Cisco PVM’s Application Response Time Monitoring feature lets you correlate response time data from various NAMs and provides you with information on how much time the traffic spent in the network. Armed with this information, you can quickly identify whether the problem is in the network or in the application, and direct resources toward solving the issue instead of identifying it.

Historical Information

Cisco PVM provides a highly scalable datastore for retaining historical traffic information. The raw traffic data and the historical aggregated data are by default stored for long periods of time (up to 3 years) in the datastore.

Real Time and Trending reports

Cisco PVM also provides comprehensive real-time and trending reports to help you with effective capacity planning, trend analysis, and network status monitoring. Cisco PVM includes a rich set of report suites and a highly flexible scheduler. The ability to automatically run reports, when used in conjunction with real-time and trending reports is invaluable when trying to monitor your network and troubleshooting it. Also, reports are automatically archived so that traffic statistics are available even if the data is purged from the data store.

Proactive Monitoring

Cisco PVM’s baselining and alerting feature provides an invaluable tool to proactively monitor your network. By using this policy-based feature you can automatically baseline your network traffic patterns so you can be alerted in case of any deviations. With Cisco PVM, you can set dynamic thresholds, which allow you to account for expected variations in traffic patterns while still retaining the ability to identify anomalous traffic patterns.
