CHAP T E R

Monitor

The Cisco PVM monitor function provides near real-time and real-time access to resource data, as well
as 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.

Note Reports generated under the Monitor tab are not archived.

Monitor Navigation

Navigating Cisco PVM monitor features employs an easy-to-use interface requiring minimal clicks to
obtain the desired results. The Monitor tab opens immediately when you log in to the system, first
displaying the progress indicator while loading data, then displaying the Monitor Overview report. The
Monitor GUI provides three windows:

• Navigation Menu

• Parameters Pane

• Report Display Pane

Both the Navigation Menu and the Parameters Pane are hidden, however, when the Monitor Overview
display first opens. Figure 3-1 displays the Monitor GUI as it appears when it first opens

Monitor Navigation Menu

The Cisco PVM Generate Reports navigation menu categorizes monitoring and reports into suites. When
the Monitor GUI opens, the system automatically runs the Overview report but hides the Generate
Reports menu. Clicking the expand icon at the far left side of the Monitor GUI opens the Generate
Reports menu (Figure 3-2), defaulted to Overview, with the report suite names displayed next to
individual suite expansion icons. Clicking either the suite name (such as “Hosts”) or the expansion icon
expands the list of reports available for that suite and hides the others.

Report Suites

The report suites open when you click on either the suite name or the expansion icon in the navigation
menu. Table 3-1 describes the available report suites.

Group (DSG). The data view defaults to All NAM; you can choose another data view from the
parameters pane and click Run to refresh the Overview display with the new view.

Editing Preferences, page 2-50 for details. Additionally, unlike other TopN reports, the Monitor

Overview display allows you to drill down to detailed host, application, or DSCP reports by clicking on
a bar in one of the graphs.

Generating Reports Using Monitor

The report generation process in Cisco PVM requires minimal intervention. This section contains the
following topics:

Report Generation Process

The Cisco PVM Monitor tab opens automatically after you log in to the system. To generate reports
under the Monitor tab:

1. Log in to Cisco PVM.

2. Allow the system to display the Progress Indicator and then the Monitor Overview report.

3. Open a report suite and select a report.

4. Open the parameters pane.

5. Select the data source group, data view, desired data source (if applicable), and report type.

6. Select the time or date range (if desired).

7. Click Run.

Monitor Parameters Pane

Reports in Cisco PVM are generated with minimal input parameters: each report in the Cisco PVM
Monitor GUI uses the parameters frame at the top of the window for parameter input. Figure 3-5 shows
the Monitor parameters pane.

Note Each time you select a new report to run, the parameters pane retains the parameters from the previously

run report. The available Data Views and Report Types depend on the specific report selected. See

Understanding Data Views, page 1-13 for more information.
