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

Figure 3-1 Monitor GUI—Parameters and Navigation Hidden (default)


Note To see a single TopN chart as a larger image in the Overview pane, click directly on the magnifying glass icon in the upper right corner of the desired chart. The individual TopN chart appears in the reports pane as an enlarged graph.


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.

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

Drill-Down Link Formats

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.

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.

Drill-Down Link Formats

Figure 3-12 depicts the drill-down from a Hosts report to the Host Details report.

Figure 3-12 Sample Drill-Down Format - Hosts to Host Details

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.

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

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.

Figure 3-13 NAM Traffic Analyzer Window

Step 3 Review or change NAM or switch/router parameters in the traffic analyzer window.


Note Changes you make using the traffic analyzer affect future data aggregation and reports only.


Step 4 Close the NAM Traffic Analyzer by clicking the close button in the upper right corner of the window.


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.

This section contains the following topics:

Variables Available for Real-Time Monitoring
