View Traffic Maps for Nodes

The NNM iSPI Performance for Traffic maps help you understand traffic flows on your network. NNM iSPI Performance for Traffic maps obtain information from all the nodes that send traffic flow to your network.

The following NNM iSPI Performance for Traffic maps are available in the NNMi console:

You can view all the top destinations and applications that contribute to the traffic flow in your network at any given point of time.

  • ClosedDestination and Application Map: This map displays the top destinations and applications that contribute to the traffic flow to your network. If the applications are directly connected to an IP address, the IP address is considered a destination. Some destination IP addresses may be connected to multiple applications. The map is neither a network topology map nor a device centric map. It represents the logical views of traffic flows in a network. Top N means top N application and top N destinations grouped together.

  • ClosedTop Sources by Destination Map: This map displays the top source IP addresses that contribute to the traffic flow to a destination. You can get the information about the top contributors of traffic on your network. The map is displayed based on the IP address specified in the NNMi console. This selected IP address is considered as the source of the traffic flow. The IP address of the node from which the map is launched, should be recognized by the respective Leaf Collector.
    This map enables you to view the traffic flow heading to any destination IP address in the network. It is not necessary for the IP address to be managed by NNMi, generate the logical views of traffic flowing from the Top N sources to the specified destination in a network. This map is neither a network topology map nor a device centric map, and display the traffic flowing from each IP address if a flow generator (router or switch) has multiple IP addresses. The colors of destination IP addresses displayed in the NNM iSPI Performance for Trafficmap are not associated with the status colors in NNMi.

  • ClosedTraffic Path View : This map displays the flow of network traffic. The NNM iSPI Performance for Traffic calculates the route of data flow along the Layer 3 path between two nodes (end nodes or routers) that are enabled to export flows and presents a map of that information on the Traffic Path View. To display meaningful information in the Path View map, make sure that you select valid IP addresses in the Source Node and Destination Node fields. This map enables you to:
    Generate a topology map where the NNM iSPI Performance for Traffic information is overlaid on the NNMi information.
    Display the direction of the traffic flow.
    Deduce the metric data on the inflow side based on the reported flows on the first flow exporter in the path.
    Deduce the destination metric data by the last flow exporter on the path.
    Query the destination host IP address in the database for IP addresses entered in the map controls and Destination Host Name for the FQDN.
    When accessing the Traffic Path view map, besides applying the common filters, in the Source and Destination fields, you must designate the IP addresses at both ends of the path using either the IPv4 address.

To launch Traffic Path View:

  1. Log on to the NNMi console.

  2. Select the Actions menu in the main toolbar and select Traffic Maps, and then click Traffic Path.

    The Traffic Path view opens. The view does not show any maps by default.

  3. Specify source and destination nodes, and then click Get Data.

To launch the Destination and Application Map:

  1. Log on to the NNMi console.
  2. Select a traffic-reporting node from one of the nodes inventory views.

  3. Select the Actions menu in the main toolbar and select Traffic Maps, and then click Destination and Application Map.

To launch the Top Sources by Destination Map:

  1. Log on to the NNMi console.
  2. Select a traffic-reporting node from one of the nodes inventory views.

  3. Select the Actions menu in the main toolbar and select Traffic Maps, and then click Top Sources by Destination Map

Launch Node Reports

The Traffic Reporting Nodes inventory enables you to launch NNM iSPI Performance for Traffic reports in the NPS console with the context of a selected node. To launch a report from the inventory, right-click a node in the Traffic Reporting Nodes view (or the Threshold Exceptions Reporting Nodes view), and then select NNM iSPI Performance > Traffic Reports - Report Menu.

Alternatively, after selecting the node of your choice, click Actions > NNM iSPI Performance > Traffic Reports - Report Menu.
