Configure a Cisco NAM to Export Response Time Data

Configure the Cisco NAM Metric Agent to export response time data from a SPAN, Remote SPAN (RSPAN), network tap, or Cisco WAE to the CA Application Delivery Analysis Manager. Unlike a Cisco WAE, a Cisco NAM computes and sends response time metrics directly to the CA Application Delivery Analysis Manager, and the Cisco NAM computes response time data for all of the network traffic it receives.

When working with SPAN data, it is best to configure the SPAN from the host switch. We recommend that you use SPAN data so that tier-to-tier traffic can be monitored. RSPAN data can experience delays before processing within the Cisco NAM, but some cases call for its use.

After you configure the Cisco NAM Metric Agent to export computed response time statistics to the CA Application Delivery Analysis Manager, the management console automatically adds the Cisco NAM to the list of available monitoring devices.

Use the Cisco NAM Traffic Analyzer console to:

Follow these steps:

  1. Enable response time data export on the Cisco NAM:
    1. Open the NAM Traffic Analyzer console.
    2. Click the Admin tab.

      The Admin tab opens.

    3. Click System.

      System Overview opens.

    4. Click Response Time Export.

      External Response Time Reporting Console Export opens.

    5. Select Enable Export and click Apply.
    6. Verify that the Cisco NAM is updating its configuration to export data to the management console by clicking Diagnostics on the Admin tab.

      The System Alerts page displays the Cisco NAM logging messages.

  2. Validate the active SPAN sessions in the running-configuration and save them to the startup-configuration:
    1. In the NAM Traffic Analyzer user interface, click Setup, and click NAM Data Sources.
    2. Select a SPAN session from the list and click Save to save the active SPAN session in the running-configuration to the startup-configuration (for switches running Cisco IOS software only).
    3. Repeat the previous step for each SPAN session that you want to see in the management console.
  3. View the SPAN data:
    1. In the NAM Traffic Analyzer user interface, click Monitor, and click Server, Response Time. Sort to find the servers with the highest number of clients.
    2. To view detailed information, select a server and click Details.
