    Monitoring the Service Summary Details of Layer 3 VPN Services for Optimal Debugging

    You can view the Service Summary page of a particular service to display the consolidated and cumulative status of a service. The overall information pertaining to the service that you can obtain from the different widgets displayed on this page enables you to navigate to the appropriate device or service settings page and modify the configuration parameters appropriately. You can view the connection between the different endpoints and also examine the statistics on the packets and bytes traversering through the endpoints. Using the Service Summary page, you can also select the source device for which you want to view the transport metrics and the traffic statistics on the other pages displayed in Monitor mode for the specific service. This page enables you to obtain an effective graphical view in the form of tables of statistics and charts to view the health and performance of devices and services in your network, which enables you to analyze and troubleshoot the parameters that are causing traffic-handling errors.

    Note: The values and statuses of the parameters displayed in the graphs and tables of different widgets are refreshed, based on the polling interval configured on the Monitoring tab of the Preferences page (accessible by clicking the down arrow beside the System button on the Connectivity Services Director banner and selecting Preferences).

      The Service Summary page is displayed.

    Note: The Service Monitoring Summary page is displayed, if you do not select a particular service from the Service View pane and select the L3VPN Services term in the Service View pane. The Summary page displays a consolidated view of all of the service instances for a particular service type. The customer associated with the service, type of service, service definition upon which the service order is based, the traffic rate in bits per second, and the traffic trend are displayed. Select the corresponding service from the Network Services > Connectivity tree on the View pane to navigate to the Service Summary page.

    The following widgets or widgets are displayed under this tab for L3VPN services. These statistical counters and metrics enable you to view an agglomerative snapshot of the service configured on a device.

    • Direct—Number of direct routes in the VPN tunnel for the specified node or device that are up and down

    • Local—Number of local routes in the VPN tunnel for the specified node or device that are up and down

    • Static—Number of static routes in the VPN tunnel for the specified node or device that are up and down

    • BGP—Number of BGP routes in the VPN tunnel for the specified node or device that are up and down (BGP routing information includes the complete route to each destination)

    • OSPF—Number of OSPF routes in the VPN tunnel for the specified node or device that are up and down (OSPF routes IP packets based solely on the destination IP address contained in the IP packet header)

    • Destination Count—Number of destinations for which there are routes in the routing table.

    • Total Route Count—Number of routes in the routing table and total number of routes in the following states:

      • active (routes that are active)

    VPN Traffic Trend

    This widget displays the total number of egress packets (packets that are sent out) or traffic passing through all the UNI or customer-edge (CE) interfaces associated with the particular service. The date and time at which the page was last updated is shown. A line graph is displayed with time on the horizontal axis and the number of output bytes on the vertical axis.

    From the Time Interval drop-down box, select 1 Hour, 8 Hours, 1 Day, 1 Week, 1 Month, 3 Months, 6 Months, 1 Year, or Custom to specify the duration for which the data polled from devices needs to be displayed.
