  Note:

  You can also right-click a link to view the same options.

  • View details about a link—To view details such as the site name, country, site id, organization, id, and time zone:

    • Hover over a link row in the table and click the Details icon. The Link - Device A to Device Z appears. On the Link - Device A to Device Z page that appears, you can view the Interface Stats tab and the Details tab.

    • Select the link on the table and click More > Show Detail. On the Link - Device A to Device Z page that appears, you can view the Interface Stats tab and the Details tab.

    On the Interface Stats tab, you can view the device name, interface name, and management IP address of device A and device Z. On the Details tab, you can view the node id associated with the interfaces, interface IPv4 address at the two nodes, interface name, interface bandwidth, live status, and the operational status of the interface. The Link - Device A to Device Z page is movable so, you can pin it anywhere on the screen.

  • Filter links on the topology map—To display only the selected link in the topology map, select Filter Selected Link. To undo the filter, right click a blank space on the topology map and click Reload Network.

• View historical data—Paragon Automation enables you can view the historical data. Historical data provides you valuable insights into past trends and patterns.

  Note:

  For Paragon Automation to collect historical data, you need to do the following:

  1. You need to enable the collection of statistics.

     1. To collect historical data for interface traffic, you need to enable traffic engineering while creating a device profile. For more information, see Add a Device Profile

        .

     2. To collect historical data for interface delay, you need to enable link delay measurements. For more information, see https://www.juniper.net/documentation/us/en/software/junos/is-is/topics/topic-map/enable-link-delay-advertise-in-is-is.html

  2. Enable dynamic topology so that you can view real-time changes in your network. For more information, see Dynamic Topology Workflow.

  You can view the historical data for the following:

  • Interface Traffic—View a graphical representation of the link traffic (in bps) for interface A and Z based on the time range selected from the Period list. A Link Traffic pop-up appears, which you can pin anywhere on the screen using the pin icon. From the Period list, you can select an option to view the traffic data for Previous 3 Hours, 1 day, 1 Week, or Custom time ranges.

    You can choose to auto refresh the data or manually refresh the data.

  • Interface delay—View a graphical representation of the link delay (in milliseconds) for interface A and Z based on the time range selected from the Period list. A Link Delay pop-up appears, which you can pin anywhere on the screen using the pin icon. From the Period list, you can select an option to view the delay data for Previous 3 Hours, 1 day, 1 Week, or Custom time ranges.

    You can choose to auto refresh the data or manually refresh the data.
