real time interface monitor

I have an interface connected internet line with bandwidth 10MB can i monitor B.w utlization real time , meaning can paloalto draw a graph time and b.w at every moment i can see ultization may 5 MB ..5.1MB 9MB or something like that . or i must use a netflow from paloalto and third party to draw this graph

Hi @Ahmed_Fahmy

 

For continuous monitoring you'd need a netflow tool as this would give you historical data.

If you have QoS enabled (not necessarily enforced, simply enabled on the interface) yoiu can also see a graph for the interface, but it only starts the moment you open the graph tool in the webinterface.

Pan(w)achrome does some basic graphing for real time troubleshooting. 

 

For more historal reporting, you would need NetFlow or SNMP monitoring. LibreNMS is a popular choice for SNMP monitoring. I believe there's a NetFlow plug-in documented. Setting up SNMP or NetFlow on the PAN is pretty trivial.

 

Depending on your environment and network layout, you would either need to monitor the PAN or the switch where your ISP link and PAN connect.

Enable QoS on the physical interface you want to monitor.  You don't have to actually create any QoS Policies or anything, just enable it on the interface.

 

Then, when on the Network Tab --> QoS page, you'll see a Statistics link beside the interface name.  Click on that, and you'll get a real-time graph of the last X minutes (where X I think is 2 minutes, but might be 5; definitely no more than the last 10).
