Cisco® Performance Visibility Manager (PVM) is a proactive network and application performance monitoring, reporting, and troubleshooting system for maximizing network availability. Cisco PVM increases early visibility into network and application behavior issues, to identify them before they become critical.

Product Overview

Cisco PVM gives visibility to the performance of your network and application resources. Cisco PVM can provide an intuitive and integrated end-to-end view of network traffic, protocol types, and application and host bandwidth usage. It provides a centralized network view of the application performance, tracks the application response times, localizes the cause of application performance problems, and can account for the impact of other traffic on application performance. Cisco PVM provides critical performance information through a GUI for troubleshooting, traffic analysis, monitoring, and capacity planning. It includes comprehensive, preconfigured reports that provide a complete assessment of performance. Cisco PVM can automatically establish a baseline network performance level and then proactively monitors for various deviations to that baseline so that network performance problems can be identified and resolved before end users are severely affected.

Traffic Analysis

Cisco PVM aggregates and correlates data from multiple Cisco NAMs and network devices to analyze traffic on your network. It provides details about the protocols, hosts, conversations, differentiated services, VLANs, switch ports, and router interfaces. Cisco PVM performs Top-N analysis to identify top talkers and top protocols in the network. It supports several data visualization modes including tabular text and graphics so that you can easily see what is going on in your network (Figure 1). Cisco PVM stores the collected and analyzed information for historical reporting and further analysis on demand.

Application Response Time Monitoring

Cisco PVM collects application response time (ART) data from multiple Cisco NAMs and correlates the data to determine the cause of poor application performance. Cisco PVM breaks down each response time measurement into average network delay and average server delay metrics and displays the data in a set of intuitive tables and graphs (Figure 2). This allows you to quickly identify whether the problem is caused by the network or by the application. Cisco PVM stores the collected information for historical reporting and further analysis on demand.

Proactive Monitoring

Cisco PVM performs automatic baselining for each statistic and metric combination based on current and previous performance data collected. The designated amount of deviations from the baseline results in alerts generated as threshold-crossing events so that problems can be detected before users are affected (Figure 3).

Figure 3. Threshold-Crossing Alert


Cisco PVM can retain performance data for one year by default; the retention period is user configurable. The real-time and near-term historical information allows you to distinguish what is happening now as opposed to what happened in the recent past. The GUI provides comprehensive network visibility to help you quickly pinpoint trouble spots and obtain details for further troubleshooting.


Cisco PVM provides a set of preconfigured reports on traffic analysis, bandwidth utilization, and ART. Reports, accessible through the Web-based interface, can either be scheduled or requested on demand. The report types include real-time, historical, and trending views. The historical reports include daily, weekly, monthly, annual, and custom interval reports based on start and end dates. Table 1 outlines the various suites of report types available from Cisco PVM.

Table 1. Report Suites

Suite Name



The Applications reports provide detailed and historical information about the applications on your network, how these applications utilize the bandwidth, which hosts access the applications, and which pair of hosts generated the most traffic.


The Hosts reports identify the hosts that are using the bandwidth, the top hosts in your network, and the protocol usage.


The Conversations reports provide traffic statistics for each pair of hosts, application protocol usage, all conversation partners with their corresponding protocols, number of packets, and byte counts. The reports can be used to determine the most “talkative” host IP pairs for traffic from a specific protocol and location.


The Differentiated Services Code Point (DSCP) reports monitor traffic by DSCP allocations defined by quality of service (QoS) policies. These reports can be used to refine the QoS policies in your network and identify violations of QoS policies.


The VLANs reports allow you to analyze the amount of traffic, and show which applications and hosts are consuming network bandwidth on your VLANs.

Switch/Router Link Utilization

The Switch/Router Link Utilization reports include port names, bytes, packets, broadcast packets, multicast packets, and errors collected for switches and routers.

Application Response Time

The Application Response Time reports provide response time statistics for your critical applications.

Data collection and aggregation from multiple Cisco NAMs

The centralized and integrated end-to-end network view provides a high-level operational perspective so that trouble spots can be quickly identified, thereby accelerating the resolution process.

Traffic and bandwidth analysis including Top-N analysis

Cisco PVM identifies the types of traffic running in the network. It identifies the top talkers, the top protocols, the most utilized links, and so on. You can differentiate your business-critical applications from your recreational traffic and understand how your business actually uses the network infrastructure. This helps you make effective decisions to optimize the usage of your network to best meet your business needs and prevent misuse of critical resources.

ART collection and correlation

Cisco PVM can identify whether the response time problem is caused by the network or by the application server. The ability to quickly identify problem sources can greatly minimize the impact to your business.

Real-time traffic monitoring and alerts based on threshold settings and baselining

Cisco PVM automatically profiles and monitors your network and application behavior. This proactive approach is essential in rectifying potential issues before they affect your business.

Real-time, historical, and trending reports

The comprehensive reports help you with effective capacity planning, trend analysis, and network-status monitoring.

Management of multiple Cisco NAMs including the capability to invoke the NAM Web-based GUI

The full integration with Cisco NAMs provides the capability to easily navigate directly to NAMs for faster and further troubleshooting and analysis.

Integration with CiscoWorks Device Credential Repository

This integration minimizes the ongoing administrative task of managing your network equipment.

Product Architecture

The Cisco PVM architecture (Figure 4) consists of a highly scalable and modular real-time data collection, correlation, and aggregation application suite and infrastructure that provide centralized and integrated end-to-end performance views of networks and applications.

Figure 4. Cisco PVM Architecture

The collection layer supports a number of collection adapters. The adapters are designated to support the managed Cisco NAMs and associated network devices. The Cisco PVM collection capability is highly customizable and configurable to give you a high degree of control and scalability.

The mediation layer consists of a number of applications. The analysis, aggregation, and correlation engine can process near real-time data with management intelligence for proactive monitoring, baselining, trend analysis, and QoS assurance.

The presentation layer presents the aggregated and integrated data for comprehensive visibility and rich and flexible reporting and viewing capabilities. The Web-based client application uses Java 2 Platform, Enterprise Edition (J2EE) technology for management operation, management information navigations, and views including reporting and alerting.
