Monitoring performance
Using WAN Opt. & Cache widgets, you can confirm that a FortiGate unit is optimizing traffic and view estimates of the amount of bandwidth saved. These include peers manually added to the configuration as well as discovered peers.
To add WAN Opt. & Cache widgets go to Dashboard > Status > Add Widget > WAN Opt. & Cache and add WAN Opt. Monitor and Peer Monitor.
Wan Opt. Monitor
The Wan Opt. Monitor shows how WAN optimization is reducing the amount of traffic on the WAN for each WAN optimization protocol by showing the amount of WAN and LAN traffic. If WAN optimization is being effective, the amount of WAN traffic should be lower than the amount of LAN traffic.
Peer Monitor
The Peer Monitor lists all of the WAN optimization peers that a FortiGate unit can perform WAN optimization with.
