Map Flow Objects

This documentation applies to NMS version 5.4. An online version of the software can be found here.

The Object Mapping page enables you to map the indicators on the objects that plugins poll to a flow interface. This enables you to display a FlowFalcon report of the flow data that is related to the poll data from an indicator that appears in an Instant Graph.

To access the Object Mapping page from the navigation bar, click the Administration menu, select Flow Configuration, and then select Object Mapping.

When you enable the SNMP plugin SNMP plugin for a device and you enable the device to send flow data to SevOne NMS, most SNMP objects are automatically mapped to their corresponding flow interface. For other plugin objects and SNMP objects such as QoS, the Object Mapping page enables you to map the indicator to an interface and to define the FlowFalcon report parameters that are applicable for the data.

Example: To display the flows for QoS Queues, create an object mapping that uses a FlowFalcon view that contains DSCP and has an appropriate filter to display a FlowFalcon report of the traffic that moves across the queue.

Map List

The list displays the mapping relationship between an indicator and its corresponding flow interface, the FlowFalcon view metric, the FlowFalcon view, and the FlowFalcon report filters.

  • SevOne NMS Device - Displays the name of the device that contains the indicator the plugin polls.

  • SevOne NMS Plugin - Displays the name of the plugin that polls the object that contains the indicator.

  • SevOne NMS Object - Displays the name of the object that contains the indicator you map to a flow interface.

  • SevOne NMS Indicator - Displays the name of the indicator you map to a flow interface.

  • Flow Device - Displays the name of the device that contains the interface that sends flow data to SevOne NMS.

  • Flow Interface - Displays the name of the flow interface to which you map the indicator.

  • Flow Direction - Displays the mapping direction.

  • Metric – Displays the FlowFalcon view metric the FlowFalcon Reports page uses for the FlowFalcon report. This column appears when you select the Advanced FlowFalcon Views check box on the Cluster Manager Cluster Settings tab.

  • View - Displays the name of the FlowFalcon view the FlowFalcon Reports page uses for the FlowFalcon report that displays the flow information for the indicator/interface.

  • Filter - Displays the name of the filter you define to apply to the FlowFalcon report.

Manage Mappings

When multiple objects rely on flow data from a single interface you can map multiple objects to a single flow interface, even if the objects are on different devices. Objects for which you define a mapping display a NetFlow button when you create an Instant Graph or when you chain an attachment from the report for the objects. The object mapping includes the designation of the FlowFalcon view and the definition of the report filters for the FlowFalcon Reports page to use to display the flow information you specify. When you click the NetFlow button on an instant graph, the FlowFalcon Reports page appears with the view, settings, and filters you define from the Object Mapping page.

Click images/download/attachments/6521003/actionold.png and select Add New Mapping or select Edit to display a pop-up that enables you to define the mapping relationship.

SevOne NMS Device

The SevOne Device section enables you to select the plugin discovered indicator to which to map the flow interface.

  1. Click the Device drop-down and select the device that contains the indicator.

  2. Click the Plugin drop-down and select the plugin that polls the indicator.

  3. Click the Object drop-down and select the object.

  4. Click the Indicator drop-down and select the indicator.

Flow Device

The Flow Device section enables you to select the flow interface to which to map the indicator.

  1. Click the Device drop-down and select the flow device that contains the interface.

  2. Click the Interface drop-down and select the interface to which to map the indicator.

  3. Click the Direction drop-down and select the direction of the interface mapping.

View

The View section enables you to select the FlowFalcon view to use for the FlowFalcon report.

  1. Click the Metric drop-down. This field appears when you select the Advanced FlowFalcon Views check box on the Cluster Manager Cluster Settings tab.

    • Select None to display all views in the View drop-down list.

    • Select Bandwidth to populate the View drop-down list with FlowFalcon views that focus the report on the volume of traffic.

    • Select Medianet to populate the View drop-down list with FlowFalcon views that focus the report on Cisco Medianet video statistics.

    • Select Response Time to populate the View drop-down list with FlowFalcon views that focus the report on the delays caused by various parts of the network. To use the Response Time metric FlowFalcon views, you must select the Monitor NAM Data check box on the Edit Device page and define the NAM settings so that a Cisco NAM device sends NAM response time data to the FlowFalcon Reports page.

  2. Click the View drop-down and select the view for the FlowFalcon Reports page to display for the indicator's interface data.

Filter

The Filters section enables you to limit the results that appear in the report. Each filter contains one or more rules. Each filter rule applies to a specific flow field. Filter rules for a field not in the view are ignored. This enables you to define filters independently from views.

The filter Boolean expression works such that for each field, SevOne NMS creates a Boolean expression that consists of the negative rules and the positive rules. The negative rules are AND'd to form a sub-expression and the positive rules are OR'd to form a sub-expression. These sub-expressions are then AND'd to form the final expression for each field. Then, each field's composite expression is AND'd to other field expressions.

  1. Click the Filter drop-down and select a filter.

  2. If no filters exist or to create a new filter, select New Filter and perform the following steps.

    1. In the Name field, enter the filter name.

    2. Click the images/download/attachments/6521003/actionold.png and select Add New Rule to display the Add New Rule to the Filter pop-up.

    3. Click the Field drop-down and select the field on which to apply the rule. Fields from the view you select appear first in the list followed by every known field from flow data. The Flow Template Status page displays field details.

    4. Click the Boolean drop-down and select Is to define the rule with an Is Boolean operator or select Is Not to define the rule with an Is Not Boolean operator. For each filter, a data row displays if allowed by all IS NOT rules and any IS rule (if existent).

    5. Click the Operator drop-down and select a comparison operator.

      • Mask - Flow data must match in the manner of IP address subnet masking.

      • Subnet - Flow data must be from the network segment you select from the Network Segment drop-down. You define network segments on the Network Segment Manager.

    6. Click Add to save the rule.

    7. Repeat these steps to add additional rules to the filter.

    8. After you add the rules to the filter, click Save Filter above the rules list.

  3. To modify or copy an existing filter, click the Filter drop-down and select a filter.

    1. Select the check box for the rule to edit then click the Action icon and select Edit to display the Add New Rule to the Filter pop-up.

    2. Click the Field drop-down and select a field.

    3. Click the Boolean drop-down and select Is or select Is Not.

    4. Click the Operator drop-down and select an operator.

    5. Click Add on the Add New Rule to Filter pop-up to save the rule.

  4. To delete a filter, click the Filter drop-down and select the filter to delete. The rules list displays the rules for the filter you select. Click Delete Filter to delete the filter.

  5. Click Save as New to create a copy of the mapping or click Save to save the mapping changes.
