Scheduling Device Collection for Analytics via Netconf

 

The NorthStar Controller Analytics features require that the Controller periodically connect to the network in order to obtain the configuration of the network devices. It uses this information to correlate IP addresses, interfaces, and devices. There are three types of collection tasks that can be scheduled in NorthStar:

  • Netconf

  • SNMP (tunnel and interface traffic)

  • Link latency

Note

This topic only addresses Netconf device collection. For information about SNMP and Link Latency collection, see Data Collection via SNMP.

Completion of device profiles (Administration > Device Profile) is a prerequisite for successfully running collection tasks.

To schedule a new collection task, navigate to Administration > Device Collection.

  1. Click Add in the upper right corner. The Create New Task window is displayed as shown in Figure 1.

  2. Enter a name for the task and use the drop-down menu to select the task type as Netconf Collection. Click Next to display the first Create New Task – Netconf window as shown in Figure 2.

    You have the following options in this window:

    • At this time, the only profile available for collection is the liveNetwork.

    • All devices or Selected devices.

      For Selected devices, you are presented with a list of devices from which to choose. Click the Collect check box for each device to be included.

    • Use management IP (the default is yes).

    • Parse collection (the default is yes).

      Parsing reads the content of the files and updates the network model accordingly. If parsing is not selected, the configuration files are collected on the server, but not used in the model.

    • Concurrent threads (the default is 16).

      This specifies how many devices can be simultaneously connected to save time on the overall task. There is a trade-off in terms of resource utilization.

  3. Click Next to proceed to the scheduling parameters. The Create New Task - Schedule window is displayed as shown in Figure 3. You can opt to run the collection only once, or to repeat it at configurable intervals.

  4. Click Submit to complete the addition of the new collection task and add it to the Task List. Click a completed task in the list to display the results in the lower portion of the window. An example is shown in Figure 4. There are three tabs in the results window: Summary, Devices, and History.

The device collection data is sent to the PCS server for routing and is reflected in the Topology view. See Viewing Analytics Data in the Web UI for more information.
