1. Select the location containing the device on which to configure Flow and select Admin tab. Click the bearer watch to be edited. Note: Step 1 is not shown in the images above.
2. Select the Applications tab on the Edit Watch dialog
3. Ensure Collection enabled (green toggle showing)
4. Ensure Collect Flow is selected
5. Use device to test for the interface and Select the appropriate one from the list in the Device Technical Test dialog (see note 1 below). unallocated flows can also be used to select the correct interface ID number and source IP for flow, based on flows received by the agent but currently unallocated. Find out more about unallocated flows.
6. Complete the Flow exporter IP if required (see note 2 below)
7. Save

Note 1: the interface selected should generally be the same as that on the Main tab used for Link Health, so a direct comparison can be drawn between Link Health volumes and Flow information.
However for operational reasons perhaps due to WAN traffic being encrypted, an alternative interface may be needed. Take care to ensure the interface which has Flow analysis applied in the router configuration corresponds with the interface selected in Highlight for Flow monitoring.
(For Cisco) Compare with the output from show ip flow interfaces command

Note 2: the "Flow exporter IP" should be the source IP of the Flow packet, usually corresponding to the (Cisco) configuration ip flow-export source or the flow exporter source commands. Compare with the output from the show ip flow export command

If Flow monitoring fails to start after 30 minutes, refer to Troubleshooting Flow or contact us

To identify Flow watches that are no longer reporting refer to the Admin Watch report. Any Flows with last good sample prior to today requires Troubleshooting.
