As mission-critical workloads migrate to virtual servers, visibility into the virtual switching infrastructure becomes critical to manage end-to-end service delivery. The virtual switching layer extends the network to the virtual servers. Lack of insight into this layer affects the ability of network administrators to manage application services. In addition, the fluidity of the virtual infrastructure, in terms of workload-driven dynamic resource allocation or virtual server migrations across hosts, poses a new set of management challenges. In this dynamic environment, network administrators are not only responsible for troubleshooting application performance issues but also for making sure that the network is ready to support resource scaling in real time. This demands deeper network visibility and analytics to present meaningful and consistent performance information for network administrators.

Product Overview

Cisco Prime Network Analysis Module (NAM) for Nexus 1010 allows network administrators to extend operational visibility into Cisco Nexus 1000V Switch deployments (Figure 1). The Cisco Nexus 1000V Switch is a software switch on a server that delivers Cisco Virtual Network Link (VN-Link) services to virtual machines (VMs) hosted on that server. This distributed switch has two major components: the Virtual Ethernet Module (VEM) and the Virtual Supervisor Module (VSM), which manages the VEMs. A VSM can itself be deployed as a virtual machine; as an alternate deployment scenario, the Cisco Nexus 1010 Virtual Services Appliance can host multiple Virtual Supervisor Modules (VSM) along with a number of Virtual Service Blades (VSBs) such as Cisco Prime Network Analysis Module (NAM) and Cisco Virtual Security Gateway (VSG).

The Cisco Prime portfolio of enterprise and service provider management offerings supports integrated lifecycle management of Cisco architectures and technologies based on a service-centric framework. Built on an intuitive workflow-oriented user experience, Cisco Prime products help increase IT productivity and reduce operations costs through innovative management solutions for the network services, infrastructure, and endpoints.

Integrated with the Cisco Nexus 1010 appliance, the Cisco Prime NAM offers combined network and application performance visibility essential to address service delivery challenges in next-generation data centers. The Cisco Prime NAM for Nexus 1010 allows you to effectively use embedded management features, such as Encapsulated Remote Switched Port Analyzer (ERSPAN) and NetFlow, on the Cisco Nexus 1000V Switch to:

   Analyze network usage behavior by application, host/VM, and conversation to identify bottlenecks that may affect performance and availability

   Troubleshoot performance issues with extended visibility into VM-to-VM traffic, virtual interface statistics, and application response times

   Assess impact on network behavior due to changes such as VM migration, new application deployment, and port profile update

   Improve the efficiency of your virtual infrastructure and distributed application components with comprehensive traffic analysis

As a distinctive advantage, Cisco Prime NAM allows you to monitor the network and virtual machines uninterrupted by VMotion operations.

Reinspired user experience

Cisco Prime NAM Software 5.1 for Cisco Nexus 1010 introduces a next-generation GUI that helps accelerate troubleshooting and optimization decisions. It offers preconfigured dashboards that provide a comprehensive graphical overview of network performance so you can immediately grasp if all is well or if a problem is emerging. It also includes prepackaged interactive reports with helpful features such as contextual navigation, advanced filters, and one-click packet captures.

Flexible site-based monitoring

This feature allows you to view network and application performance by logical groupings or sites that you can create to mirror your network topology. For example, you can create sites by geographic locations, departments, or even managed customer networks and view performance data on a per site basis making it easier to obtain both a global and local view of how your applications are performing.

Historical analysis with embedded Performance Database

The new Performance Database stores computed data so you can go back to the past to learn what happened on your network when a particular event occurred. The data is available to troubleshoot unanticipated performance issues or to analyze optimization needs.

Packet Capture, Decodes and Error Scan

Cisco Prime NAM for Nexus 1010 implements packet capture on ERSPAN data source to help investigate and troubleshoot complex performance problems. Cisco NAM’s capture and decode capability provides depth and insight into data analysis using trigger-based captures, filters, decodes, and a capture analysis toolset to quickly pinpoint and resolve problem areas. The new Packet Capture Error Scan automatically highlights packet-level anomalies eliminating the need to manually inspect the packet data to find the “needle in the haystack.”

NetFlow Version 9 Data Export

By exporting analytics in a standardized format, this new capability allows you to use computed NAM data to feed in-house or third-party reporting applications that you already own, building up additional value and building out existing investments.

Features and Benefits

Traffic Analysis

As an integrated solution, Cisco Prime NAM for Nexus 1010 offers real-time traffic analysis views and long-term interactive reports to help enable network administrators to analyze and optimize the performance of the virtual and physical network. Cisco Prime NAM can analyze NetFlow data exports or ERSPAN packet streams from the Cisco Nexus 1000V Switch to gather information on applications, hosts, virtual machines, and conversations.

Application monitoring identifies applications on the network, reports how much bandwidth has been consumed, and detects which hosts or virtual machines are using which applications. Host and conversation pair monitoring provides bandwidth consumption per host or virtual machine and shows which hosts/virtual machines are talking to each other. Monitoring applications, hosts, virtual machines, and conversations can help to spot bottlenecks before the virtual network suffers blows to performance and availability.

Besides delivering a real-time snapshot of bandwidth usage and consumption, Cisco Prime NAM can also deliver a longer term view (Figure 2) of how the bandwidth was used so the network administrator can analyze trends.

Application Performance Intelligence

Cisco Prime NAM analyzes the TCP-based network transactions to provide comprehensive set of statistics to help troubleshoot application response time issues. It allows network administrators to analyze performance metrics, such as network delay, round-trip time, retransmission time, and so on, to identify the cause of degradation. For example, server resource issues affecting application performance can be identified by network metrics such as application delay and server response time. Figure 3 provides a glimpse into application response time analysis report which shows increase in the transaction time for HTTP application attributing the cause to be increase in server response time.

Figure 3.      Isolating Application Response Time Issues

The application performance data can also be analyzed over time to identify trends. The capability allows administrators to assess the impact on application performance due to changes such as dynamic virtual machine creation, virtual machine migration, port profile updates, and so on.

Quality of Service Analysis

Using the Cisco Prime NAM DiffServ monitoring capabilities, applications, hosts, and conversations participating in each grouping of DiffServ classes can be identified (Figure 4). This information can be used to validate and fine-tune QoS planning assumptions when creating or updating port profiles. It can also be used to detect whether an application is misclassified or contending for limited virtual network resources with non-business critical traffic.
