Cisco PVM Overview
Cisco PVM is a centralized network management tool that enhances the Network Analysis Module (NAM) for Cisco Catalyst 6500 Series switches, 7600 Series routers, and Branch series routers by providing visibility into the network that aids troubleshooting and QoS management. Cisco PVM is designed to:
•
Give end users visibility into their networks and applications.
•
Collect, aggregate, and correlate data from multiple NAMs and network devices.
•
Provide critical performance information through a graphical user interface (GUI) for troubleshooting, traffic analysis, monitoring, and capacity planning.
•
View alarms showing deviations from an established baseline of network and application traffic flows.
•
Collect application response time (ART) data from several NAMs and correlate the data to provide end-to-end response time information for applications.
•
Monitor the network continuously to identify network performance problems so that they can be resolved before end users are affected.
•
Provide a consistent and complete assessment of performance with comprehensive, pre-configured reports.
Cisco PVM is a highly scalable and distributable real-time data collection, correlation, and aggregation engine providing a centralized and integrated end-to-end (E2E) network view. It adds value to the Cisco NAM Traffic Analyzer, as well as other applicable Cisco performance and traffic management product suites.

•
Edit file
$JBOSS_HOME\server\default\deploy\http-invoker.sar\META-INF\jboss-service.xmland update each mbean InvokerURLPrefix and InvokerURLSuffix to use the proper protocol and port number (they occur four times). Following are examples using HTTP and port 8080:
<attribute name="InvokerURLPrefix">http://</attribute>
<attribute name="InvokerURLSuffix">:8080/...</attribute>
Step 2
Configure JBoss Web server (Tomcat):
a.
Stop PVM.
b.
Edit the file: $JBOSS_HOME/server/default/deploy/jbossweb-tomcat41.sar/META-INF/jboss-service.xml to enable non-secure access to PVM GUI via port 8080
c.
Comment out (by enclosing between '<!--' and '-->' strings) the corresponding connector section. After commenting, the section should appear as follows:
<!-- SSL/TLS Connector configuration using the SSL domain keystore<ConnectorclassName="org.apache.coyote.tomcat4.CoyoteConnector"address="${jboss.bind.address}"port = "8443"minProcessors="5"maxProcessors="50"enableLookups="true"acceptCount="10"debug="0"connectionTimeout="50000"scheme="https"secure="true"><FactoryclassName="org.apache.coyote.tomcat4.CoyoteServerSocketFactory"keystoreFile="${jboss.server.home.dir}/conf/ssl.keystore"keystorePass="changeit"protocol ="TLS"/></Connector>-->
d.
Uncomment the corresponding connector section. After un-commenting, the section should appear as follows:
<!-- A HTTP/1.1 Connector on port 8080 --><Connector className="org.apache.coyote.tomcat4.CoyoteConnector"address="${jboss.bind.address}" port="8080" minProcessors="5" maxProcessors="50" enableLookups="true" acceptCount="10" debug="0" connectionTimeout="5000" useURIValidationHack="false"/>

Navigation Tabs
Cisco PVM provides the following easy-to-use navigation tabs directing you to functional areas. The following sections display figures depicting the location of Cisco PVM navigation tabs and the menu items that appear beneath each tab.
Note
Detailed information, including specific procedures for each tab, is found in the remaining chapters of this guide.
Setup
Setup allows users to:
•
View, add, edit, delete, and import NAMs and supporting switches and routers, as well as enable or disable data collection on individual NAMs.
•
Define thresholds for monitoring in the Alert Viewer.
•
Define data collection groups, called Data Source Groups, by NAM or switch/router data flows; the data source groups are then available for selection in the reporting and monitoring suites.
•
Define system configuration preferences including default threshold severity levels, baseline duration and re-calibration periods, and the system-wide collection cycle.
•
Access the NAM Traffic Analyzer for a selected NAM.
The Setup tab also provides access to the external NAM configuration web interface (see Figure 1-4).
Figure 1-4 Setup Tab
Monitor
The Monitor tab allows you to monitor resources based on information from a single NAM or from multiple NAMs across the network, in near real time. This gives you the ability to monitor specific sections of the network or to access an All NAMs view that displays multiple NAMs across the network for quick comparisons.
When the Monitor tab displays, as well as every time you run a report, the Generate Reports menu area and the report parameters pane are collapsed. Click the Expand/Collapse icons on the upper left and right sides of the window to open the list of available reports and the parameters pane. Figure 1-5 shows the default Monitor display.
Figure 1-5 Monitor Tab—Default Display
•
Real-time charts are linked to reports generated from the Monitor GUI, and provide a visual display of changes in data flows by data source and variable for a selected NAM or switch/router. These charts display true real-time information.
•
Trending reports are linked to reports generated in the Monitor GUI, and provide a magnified view of raw data for analysis of abnormal or problematic traffic patterns.
Reports
The Reports tab provides an extensive set of web-based reporting features that allow you to take a snapshot of activity for a specified reporting period. Reports are automatically archived and can be retrieved and printed in the report viewer.
When the Reports tab displays, the menu of available reports (Generate Reports) is expanded and defaults to the Applications report. Every time you run a report, however, the menu area collapses. Click the Expand/Collapse icon on the upper left of the window to show or hide the list of available reports. Figure 1-6 shows the default Reports tab display.

•
Trend reports are linked to reports generated in the Reports GUI, and provide a magnified view of raw data for analysis of abnormal or problematic traffic patterns.
Note
For a summary of the differences between the Monitor and Reports tabs, see Monitoring and Reporting Functions.
ART
The ART tab (see Figure 1-7) provides access to reports for Network Flight, Server Response, and Client-Server Response Times, as well as the Client Investigation Report. The reports under the ART tab allow specialized views of response time and other client/server data with links to protocol-specific information. Users can also set up ART Groups for aggregation of ART-specific data.
Figure 1-7 ART Tab—Setup Default
Alerts
The Cisco PVM Alerts tab (Figure 1-8) displays service alerts. Cisco PVM polls data flows to detect user-defined thresholds that have been violated. Using the filter feature, you can display a list of threshold and system alerts occurring within a specific time period. You can select a start and end date during which the alerts occurred and specify the severity of the alert to display only those records meeting the specified criteria. Details of an alert management record can be viewed from the Alerts list. Additionally, you can stop or resume monitoring for specific alerts by enabling and disabling Thresholds under Setup.
Figure 1-8 Alerts Tab
Note
Alerts are displayed in continuous mode, so an alert related to the same source will continue to appear until the set threshold value is no longer violated. You can therefore see an alert from the same source appear at progressively lower severity levels until it clears. Threshold values are assigned under the Setup tab.
Admin
The Admin tab (see Figure 1-9) allows you to view security events and change passwords, as well as add, edit, view, and delete user accounts.
Figure 1-9 Admin Tab
Understanding Data Views
The Cisco PVM Monitor function displays near real-time traffic data views for applications, hosts, conversations, switches/routers, VLANs, and response times. You can view network resources based on these types and drill down to access details about a particular resource. The GUI allows you to select key traffic views based on NAM aggregation data types.
This section contains the following topics:
You select which data to view on generated reports using the drop-down selection menu available in the parameters pane at the top of the Monitor window. You can select a Data Source Group (DSG) and one of the following types of data views:
•
Data Source—displays data for a specific data source available in the selected DSG.
•
All NAM—displays data for all NAMs in the DSG.
•
Aggregated—displays collated data from multiple NAMs and data sources across the network.
To supply traffic information to the Monitor and Reports functions, Cisco PVM uses the Data Source Group, a logical collection of raw data sources that users can customize into groups for NAMs, switches, and routers. Cisco PVM uses DSGs for those system functions that require calculating statistics over multiple data sources, such as Thresholds and reports.
When you set up a DSG, you can view all existing data sources by NAM or supporting device, and you can specify only those sources you want to include in the group. You can therefore combine similar data sources from multiple NAMs or supporting devices into a single DSG.
The following figures show a DSG example and the possible data views that can be generated in reports. The red line in Figure 1-10 shows the numbered data sources selected from specific NAMs that define the DSG:
•
Sources 2, 3, and 4 from the West NAM
•
Sources 2 and 3 from the North NAM and
•
Sources 1 and 2 from the East NAM.
Figure 1-10 Schematic of a Data Source Group
The following three figures depict which data sources from the DSG are selected for each of the available data views. The red circle in Figure 1-11 indicates that data source 3 only has been selected from the DSG as the source to use to generate the report.
Figure 1-11 Single Data Source View
The red ovals in Figure 1-12 show that data sources from all NAMs in the DSG have been chosen as the source to generate the report.
Figure 1-12 All NAM View
Figure 1-13 shows that the entire DSG has been chosen as the data source for generating the aggregated (collated) data view.
Figure 1-13 Aggregated View
Monitoring and Reporting Functions
The Monitor and Reports tabs present many of the same report suites and can display data from the same sets of sources. This section contains the following topics:
•
Monitor and Reports Comparison
•
Reports Navigation
•
Dynamic Data Displays
Monitor and Reports Comparison
The generated reports under both tabs also appear with similar layouts and drill-down capabilities. However, the purpose of the Monitor function is to provide a dynamic view of current network activity, including an auto-refresh function that regenerates the report based on a user-specified time interval. The Reports function allows you to schedule current and historical snapshots of network performance for business and network management reporting purposes, including an archive function that stores each report generated. Table 1-6 displays the key differences between the two functions.

Note
Because switch and router data sources do not support the same set of statistics, data cannot be aggregated for Data Source Groups containing both switches and routers. Therefore, Data Source Groups containing both switch and router data sources do not support the Aggregated view for monitoring and reporting.
Navigation Links
After you have run a report, navigating through generated reports is accomplished using the navigation links available in every report header (see Figure 1-15).
Figure 1-15 Report Header
TOC—(Table of Contents) Displays a list of NAMs used to generate the current report, as assigned in the selected Data Source Group. For example, if the report was generated using a data from four different NAMs, the TOC pane displays the name of each NAM as a link to a separate page in the report. Clicking TOC once opens the list in a pane to the left of the report; clicking TOC again closes the left pane.

Dynamic Data Displays
This section explains the two ways that Cisco PVM displays dynamic data:
•
Real-Time Charts—display pop-up windows that show data refreshed in real-time.
•
Trend Reports—display raw data with a trend line from selected report time periods for a magnified view of report data.
Real-Time Charts
Cisco PVM displays access to real-time data through links available in report displays. Monitoring reports that are displayed in tabular format contain a link in each table row that opens a Real-Time Chart pop-up window for the corresponding report element (such as host or protocol). Clicking the link opens a new window to monitor the details for the selected report element graphed in real time. Once opened, the chart continually refreshes to give a running view of changes in real-time traffic over the network.
Note
Real-Time Chart drill-down capability is available for all tabular reports displaying either the Data Source or All NAMs views.
For more information about Real-Time Chart functionality, see Real-Time Charts, page 3-14.
Trend Reports
Cisco PVM enables you to analyze problematic areas of the network by providing access to raw data displayed with a normalizing trend line directly from aggregated data views. Reports displaying aggregated data in tabular format contain a link in each table row that opens a Trend Report for the corresponding report element (such as VLAN ID). Clicking the link in the report display opens the Trend Report for the selected row. 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.
For more information about Trend Report functionality, see Trend Reports, page 3-18.
Enhancing Filter Operations
When filtering lists in Cisco PVM display panes, the percent symbol (%) or the asterisk (*) can be used as a wildcard character to broaden the search, but it is not required. It can be typed both before and after a variable (such as a parameter or an IP address), or it can be typed by itself to list all items available for a particular field. Leaving a field blank will return all results for that field, as constrained by other filter parameters. Filter operations in Cisco PVM are not case-sensitive.
The use of a wildcard character is not required in Cisco PVM, but you can use either the percent character (%) or the asterisk (*) as wild cards if desired. For example, to find the user "Virginia" in a list of users, you could enter any of the following strings as search criteria:
•
virg
•
irg
•
virg%
•
i*g
Leaving the field blank will return a list of all users. If you want to return to the original, unfiltered list, click Clear, then click Filter.
Displaying the Cisco PVM Version Number
If you need to contact Cisco Technical Support, please have the Cisco PVM version number ready. To obtain the version number, select the About link in the upper right portion of the Cisco PVM Dashboard. To close the About box, click OK. The About box (see Figure 1-17) opens as a pop-up window; the version number appears at the end of the first line of text and the current build number appears in the last line of text.
