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

Drill-Down Capabilities
Cisco PVM reports display hyperlinks for linking one report to another. For example, from the
Applications Report that displays a list of protocols in table rows, you can click on a Protocol hyperlink
to access the Application Details report for that protocol. This section describes drill-down rules and
design.
This section contains the following topics:
• General Rules, page 3-11
• Drill-Down Link Formats, page 3-12
General Rules
Cisco PVM reports adhere to the following rules for hyperlink access among reports:
• Each time you see a Host IP address, you can drill down to the host details.
• Each application allows you to drill down to the application details.
Drill-Down Capabilities
• Each time you see a NAM name, you can click on the name to open a new window for the individual
NAM GUI and automatically sign him in.
• Real-time charting drill-down: each time you see an “R” hyperlink, you can click on the “R” to open
a new window to monitor this report row details graphed in real-time. Drill-down capability is
available on both Data Source view and All NAM view, for all tabular reports.
• Trend Reports drill-down: each time you see a “T” hyperlink, you can click on the “T” to drill down
to this report row details graphed against the selected time period. This drill-down capability is
available for Data Source, All NAM, and Aggregated views for all tabular reports.
Table 3-3 shows the Cisco PVM reports and the reports you can access through the available drill-down
hyperlinks.

The host IP address for which the user wants to see details appears as a red hyperlink in the report shown
on the left, and its respective Host Details report, shown on the right, opens when that hyperlink is
clicked. In the Cisco PVM GUI, the second report replaces the initial report in the report display pane.
You can click Back in the report header to see the initial report.
Using Report Drill-Down Links
Drill-down links are generally available in tabular reports only. Cisco PVM tabular reports include those
run for cumulative and current rates; TopN reports do not normally allow drill-down to other reports.
The exception is the Monitor Overview TopN display, which allows drill-down to specific reports when
you click on a bar in one of the graphs.
Cisco Performance Visibility Manager User Guide

OL-8620-03
Chapter 3 Monitor
To use a report drill-down links, complete the following steps:
Step 1 Open a tabular report by running a new report or opening an archived report.
Step 2 In the table, find the linked resource about which you want more information, such as the Host ID or
Protocol.
Tip You can use the sorting arrows in the column header to re-sort the resource or performance
information, or use the pagination links in the report header to view different pages of the report.
Step 3 Click the desired resource name or application protocol hyperlink.
The drill-down report opens and replaces the display of the original report.
Step 4 Click additional resource name or application protocol hyperlinks available in the first drill-down report
to display additional reports containing details for the desired resource or application.
Opening the NAM Traffic Analyzer
Drill-Down Capabilities
You can link directly to the Cisco NAM Traffic Analyzer for NAM configuration options from Cisco
PVM reports. The traffic analyzer opens in a new window.
Note The traffic analyzer opens directly to a specific NAM only if that NAM has been set up in Cisco PVM
with the correct user ID and password (Setup > NAM in the Cisco PVM GUI) or if the current Cisco
PVM user credentials match the NAM credentials. If the traffic analyzer does not open for the desired
NAM, log in to the NAM using the traffic analyzer’s login window, or contact the Cisco PVM
administrator to obtain traffic analyzer login information.
To open the NAM traffic analyzer, complete the following steps:
Step 1 Run a report for the desired statistic.
Step 2 Click the “NAM (Type)” hyperlink at the top of the report display window.
The NAM Traffic Analyzer opens in a new browser window, signed on automatically to the correct NAM
if that NAM’s logon information has been set up in Cisco PVM or if your user credentials allow you to
access the NAM. Figure 3-13 shows the NAM Traffic Analyzer window opened just beneath the “NAM
(Type)” hyperlink.

Note Changes you make using the traffic analyzer affect future data aggregation and reports only.
Real-Time Charts
Cisco PVM provides access to real-time data through links available in tabular reports. Reports contain
a link in each table row that opens a chart pop-up for the corresponding report element, such as a host
or protocol.
The Real-Time Chart pop-up allows you to troubleshoot a specific data source by displaying a
continuously refreshed plot of its current performance. Monitoring begins as soon as the window opens.
The chart will automatically refresh every 30 seconds and additional data points will be plotted. At any
time, you can change the selected variable and click Submit to restart monitoring.

Cisco PVM provides dynamic performance reporting capability within the Reports GUI by displaying a
link to a Trend Report on each report pane. The report displays raw data for the selected network
component (such as protocol, host, or interface) with a superimposed line showing the data trend over
time, offering a magnified view of the data flow for analysis of abnormal or problematic patterns.
To see different statistics for the same report displayed as a Trend report, simply click a different metric
