Dear Anavila

PRTG can monitor traffic as long as your devices support standard protocols like SNMP.

The approach how to monitor traffic in a LAN or VLAN depends on the setup and topology of your network as well as the software and hardware used. As a first step, please have a look at the following article: https://kb.paessler.com/en/topic/2923

To started with traffic monitoring, please create a new device in PRTG and enter its IP. Then start an autodiscovery to see if PRTG can automatically detect the device and create sensors (usually one traffic sensor for each port.)
