Key Features and Benefits:

• Traffic analysis
  As an integrated solution, Cisco Nexus 1000V NAM Virtual Service Blade offers real-time traffic analysis views and targeted long-term reports to help enable network administrators to analyze and optimize the performance of the virtual and physical network. Cisco 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.
• Intelligent application performance analytics
  Cisco Nexus 1000V NAM Virtual Service Blade analyzes the TCP-based messages across the servers (virtual or physical) to provide comprehensive transaction - and session-based 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. The report shows reduction in the application delay after the administrator restarted a hung process on the application server virtual machine.
• Quality of service analysis
  Cisco Nexus 1000V NAM Virtual Service Blade supports the Differentiated Services (DiffServ) Monitoring (DSMON) MIB, which monitors traffic by differentiated services code point (DSCP) allocations defined by the quality of service (QoS) policies. Using the Cisco NAM DiffServ monitoring capabilities, applications, hosts, and conversations participating in each grouping of DiffServ classes can be identified. 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.
• Interface monitoring
  The Cisco Nexus 1000V NAM Virtual Service Blade offers visibility into traffic statistics for both virtual and physical interfaces in order to quickly troubleshoot application performance issues. Network administrators can configure any of the Cisco VSMs coresiding on the Cisco Nexus 1010 Virtual Services Appliance as managed device to monitor statistics such as percent utilization, throughput, packet discards, and errors for each interface, along with the ability to navigate to gather more details including top-N applications, hosts, and conversations. In addition, Cisco NAM can be configured to provide notification of any of these values should they exceed the thresholds to enable proactive management.
