Allow-Listing and Managing Traffic Monitors
This step allows the forwarder to recognize and accept the network flow data from the newly configured traffic monitor. The forwarder needs the allow-list in order to accept flow data from your traffic monitor.
Important: Network flow data must already be streaming to the forwarder in order for the traffic monitor's network device to appear as an option for allow-listing. You only need to allow-list one traffic monitor per forwarder.
Allow-List Your Traffic Monitors
Go to Traffic Insights > Settings > Traffic Monitors to allow-list your monitors. The Traffic Monitors tab shows the network devices you have configured as traffic monitors and which are successfully exporting network flows.
You can allow-list your monitors in one of three ways:
To allow-list all monitors, click Allow All in the message bar at the top of the screen.
To allow-list a selection, check the boxes next to the monitors you want to allow and click Allow at the bottom of the screen.
To allow-list an individual monitor, click the ellipsis on an agent's row, and select Allow.
View and Manage Your Traffic Monitors
The Traffic Monitors screen in Traffic Insights > Settings displays only the network devices you have configured as traffic monitors.
Once Traffic Insights setup is complete, the Traffic Monitors screen shows traffic flowing through each monitor in the time frame chosen. Choose from the last 2 hours up to the last 2 days. Filter results by:
Network Device IP
Network Device Name
Enterprise Agent
Site
Status
Understanding the Traffic Monitor Table
Network Device IP: Identifies the network device that is acting as a traffic monitor and is already sending flow data to an Enterprise Agent.
Network Device Name: Optional field, if a device name was configured on the device itself and SNMP device discovery has been completed. See Discovering Devices for more information.
Enterprise Agent: The name of the Enterprise Agent used as the forwarder as configured in Enabling and Managing Forwarders.
Site: Optional user-defined site name where this traffic monitor is located. Open each monitor's edit panel on the Traffic Monitors screen to edit.
Geo Location: Optional country and region where this traffic monitor is located. Defaults to the location of the forwarder the monitor exports to. Open each monitor's edit panel on the Traffic Monitors screen to edit.
Status: Either Allowed or Not Allowed.
Last Active (UTC): Date and time that this traffic monitor sent flow data to ThousandEyes.
FPS (Avg/Peak): Flow records per second sent from the traffic monitor that might be forwarded to ThousandEyes platform if allowed. Shows average and peak values.
Unsupported FPS (Avg/Peak): Flow records per second sent from the traffic monitor and discarded due to unsupported format. Shows average and peak values.
... (ellipsis): Click to Edit (and add site location or geolocation), Allow, Disallow, or Delete each row.
