Hallo Joyce,
Yes, Observium can display the bandwidth being used between two sites. If you are interested in the nature of the data flowing (e.g. destinations and protocols, etc.) then you probably need another tool like ntopng but only if your network equipment supports NetFlow/sFlow exports.
To check bandwidth being used, typically you drill down to a specific port on a router or switch and display the data graphically that way. For data flowing between sites via a VPN, you may need to look at IPsec ports, rather than physical ports. Take a look under ports:

Hallo, I have two questions that I would like to know whether it is possible to do using Observium:
- Is there a way to monitor the data that flows between site-to-site
locations? 2. How can I check the bandwidth of a device that is already in observium?
Lastly, I understand that mapping is from a 3rd party provider (OpenStreetMap), but would anyone have had a problem, whereby just from nowhere locations, that were properly mapped, are not correctly mapped anymore? A bunch of locations are showing in the middle of the sea. Thanks.
