Hello,
The easiest way to monitor your bandwidth is by using the SNMP Traffic Sensor, which allows you to monitor the incoming and outgoing traffic on a port.
(https://www.paessler.com/manuals/prtg/snmp_traffic_sensor.htm)
Depending on the devices you have, you can also use netflow or the packet sniffing sensors to gather information about
- Bandwidth usage based on source IP and port
- Bandwidth usage based on destination IP and port
- Other Bandwidth usage based on filter options. Details can be found here: (https://www.paessler.com/manuals/prtg/xflow_packet_sniffer_filter_rules.htm)
PRTG offers Top lists so you can see at one glance, who is using your bandwidths.
(https://www.paessler.com/manuals/prtg/toplists.htm)
Toplists cannot not be part of PRTG reports, though. But if you have Netflow Sensors filtering for certain IPs/Hosts then the normal sensor results can be reported and would also show bandwidth-amounts for certain IPs/hosts.
Please note, it’s not possible to filter on URL or user directly. You have to filter on a combination of all IP addresses behind a certain URL/User.
We also have some video tutorials about bandwidth monitoring.
