Hello,

I want to display the LIVE network usage that goes through my PFSense firewall. Is there a way to display this live? And not have it refresh every 10 seconds.

Kind Regards,

Hi Sven,

How do you currently monitor the bandwidth? Via SNMP Traffic Sensors? If so, then please note that you don't lose any data as the sensors monitor the traffic in a Delta. PRTG always monitors the bandwidth in deltas, these are not moment shots. As an example how the bandwidth sensors get their data:

Scan 1:
Incoming Traffic Counter: 2048
Outgoing Traffic Counter: 4096

Scan 2 after 300 seconds
Incoming Traffic Counter: 23422
Outgoing Traffic Counter: 45432

Scan 2 - Scan 1 / 300:
Incoming Traffic Speed: 71,25 byte/s
Outgoing Traffic Speed: 137,79 byte/s

No data is lost when you scan an interface every 10 minutes or every 5 seconds as we always request the Counter, not the current speed.

Best regards.
