Overview of PVM functionality

You now have an understanding of usage of Cisco PVM with some of the scenarios mentioned earlier This section will explain all the features of Cisco PVM to provide a thorough overview of Cisco PVM capabilities.

Traffic Analysis using Cisco PVM

Cisco PVM provides two ways to perform traffic analysis. For active monitoring of network traffic, use the Monitoring feature. For historical traffic analysis, use the Reporting feature. The following table provides information on when to use each feature and the differences between the two.

Monitoring

The Cisco PVM monitor function provides near real-time and real-time access to resource data, and summary views of aggregated traffic data with drill-down capability, formatted into tables and graphs for troubleshooting and analyzing current network performance. Cisco PVM displays individual and aggregated NAM metrics, including displays for single NAM data sources, for multiple NAM data aggregated across the network, and for all NAMs. Additionally, the Monitor tab displays a snapshot of current network activity immediately upon access.

Using the Monitor function, you can display near real-time and dynamic traffic data for applications, hosts, conversations, DCSP groups, switches and routers, and VLAN data. You can view network resources based on these data sources and drill down to access details about a particular resource. Reports can be viewed, printed, and saved as PDF, Microsoft Excel, and Rich Text Format files.

To access the Monitoring functionality, click the Monitoring tab. Cisco PVM automatically displays a Network Overview Report for the first DSG in the list, and the following screen is seen.
