Viewing Flow Data from a Specific Flow Source in Network Insights

SUMMARY Use the Network Activity tab to view flows that are received by JSA. You can apply a filter to view flows that are received from a specific flow source.
Ensure that the flow source is added to the deployment and that the flow source is enabled.

When you install JSA, a default_Netflow flow source is automatically added to the deployment. This flow source is enabled by default. New flow sources are created as you add flow collectors and flow processors.

When you add a Network Insights host, an input flow source is automatically created for all non-management interfaces that are available on the host.

With exception of Napatech network interfaces, the auto-detected flow sources are disabled by default, and must be enabled if you want to use them for monitoring network flows. Flow sources for Napatech interfaces are enabled by default, and cannot be edited, disabled, or deleted.

  1. Click the Network Activity tab.
  2. Click Add Filter, and select the criteria that you want to match.
    Tip:

    Reduce the options in the Parameter list by typing keywords. For example, you can type flow to find all the flow parameters.
    The filter is applied, and the search results are shown. You can add more filter parameters to further reduce the result list.
The Flow Interface column that appears in the result list might appear differently, depending on which JSA release you are using.
