Appliance overview
Use the Devices subtab to get an overview of your appliances: view a list of your appliances, then get more information about each appliance, such as services on the appliance, etc.
Appliance list
The appliance list shows your deployed appliances and whether they are reachable from the Director. You can also view the deployed configuration and take a snapshot or restore the appliance configuration should you change it.
To view the appliance list, click the Monitor tab, then click the Devices subtab. (You can also view the appliance list by clicking the Configuration tab, and then Devices.)
- Appliance summary (click to view a summary of an appliance).
- Manage appliance configuration snapshots.
- Appliance reachable from Director.

The Services subtab is a quick way to get information from a branch FlexVNF without having to sign in to the CLI and run a command. This is useful for an operations teams to track down an issue as well as for daily operational tasks—including looking at traffic flows or seeing the health of IPSec tunnels. The items shown on the Services subtab fall under two categories: Services and Networking.

Networking: Interfaces
- Interfaces—the WAN and LAN interface statistics with respect to the organization associated with the device. The table displays the latest cumulative values at the time of polling after the interface is activated, unless a clear operation is performed. The PPS (packets per second) and BPS (bits per second) counters average out over a maximum of 30 seconds. The PPS and BPS numbers represent the observable rate of a stable flow. For example, if the traffic drops to zero at the 20th second, the value of these averages will drop to zero as well, and will not use the values of the first 20 seconds to calculate the rate.
