Monitor your Network using the Monitor Mode

Monitor mode in Network Director provides you visibility into your network status and performance. You can also use the Dashboard widgets to monitor your network performance.

Network Director monitors the devices it manages and maintains the information it collects from the devices in a database. You can view this data as easy-to-understand graphs and tables—known as monitoring widgets—to quickly visualize the state of your network, spot trends developing over time, and view important details.

Monitor mode divides the monitoring activity into the following categories:

  • Traffic—Provides information about traffic on QFabric systems, switches, routers, Virtual Chassis, Virtual Chassis Fabrics (VCFs), Layer 3 Fabrics, and wireless controllers.
  • Client—Provides session information about clients connected to wireless access points and to 802.1X authenticator switch ports.
  • RF—Provides information about the wireless environment and signal performance.
  • Equipment—Provides information about the state of switches, wireless LAN controllers, interfaces, wireless access points, and radios.
  • Fabric Analysis—Displays the results of running the Run Fabric Analyzer task on a QFabric or VCF. It shows information about the health, connectivity, and topology of the fabric.

To view the state and performance of your network:

  1. Click Monitor in the Network Director banner.
  2. Use the various monitor widgets to view the status and performance of your network. The most commonly used monitoring widgets are described in the following table:

    Summary

    To access information about port utilization in either one of two places, depending on the node you select in the View pane:

    • Port Utilization monitor—This monitor, available in the Summary tab, provides a bar chart that shows the aggregate utilization of the ports on a device or devices over a period of time that you select.
    • Port Utilization task—This task, available from View > Port Utilization in the Tasks pane of the Summary or Traffic tabs, provides a bar chart similar to the Port Utilization monitor bar chart. Unlike the Port Utilization monitor, it also enables you to obtain information about individual port utilization over time when you have selected an individual device or Layer 3 Fabric in the View pane.

    1. Select a node in the View pane that contains the ports whose utilization you want to monitor.
    2. Select the Summary or Traffic tab.
    3. In the Tasks pane, select View > Port Utilization.

      If you select a node that contains more than one device, the Port Utilization Details window opens. For information about this window, see Port Utilization Details Window.

      If you select an individual device, the Utilization for Device window opens. For information about this window, see Utilization for Device Window.

      If you select a Layer 3 Fabric, the Utilization for IP Fabric window opens. For information about this window, see Utilization for IP Fabric Window.

    Traffic

    To monitor Virtual Chassis protocol statistics on a device.

    Note: This task is applicable only for Virtual Chassis and Fabric devices that are managed by Network Director.

    1. Select a node in the View pane that contains the Virtual Chassis protocol traffic you want to monitor.
    2. Select the Traffic tab.
    3. In the Tasks pane, select View > VC Protocol Statistics.

      The Virtual Chassis Protocol Statistics window opens. For information about this window, click the Help icon in the title bar of the window or see Virtual Chassis Protocol Statistics Window.

    All

    To find user sessions on the network.

    In the Tasks pane, select Tasks > Find User Session. The Search User Session window opens. For information about this window, click the Help icon in the title bar of the window or see Search User Session Window.
