current bandwidth utilization

What's the best way to check the current bandwidth utilization in the office?  We have have Internet-> PAN fw->juniper switches->users.  Is it something built into those devices to check that or install some app on the top of that, or...
 
I want to look at what bandwidth utilization I have now and estimate it's max growth based on new headcount / office expansion.

Are you looking for net bandwidth going out or internal utilization?

External.  Net bandwidth going in/out.

You might need to configure netflow on the PAN firewall and go that route.

To do that, navigate to the Device > Server Profiles > Netflow in the GUI. Feed in the information including server & port. Once you've configured the NetFlow profile, assign the profile to the firewall interface. Navigate to Network > Interfaces > Ethernet. Click the link for the interface on the Ethernet tab, and specify the NetFlow Profile.

That'll start pumping it to your netflow analyzer. It could be MRTG or Manageengine or the like.

Do you have access to the edge router/firewall?  If so, you can enable QOS with no shaping on the WAN interface and see your utilization over time and without need for export.

Thanks netcmh.  What does it mean by 'server'.  Say I don't have any servers.

Server's the box running the analyzer. Doesn't have to be a "server" could be a laptop/workstation.

Gotcha.  So it has to be something connected to the firewall via Ethernet?

You can pull the snmp data from the palo altos, we do that and use prtg to collect the data.  Works fine, you may have to add the pan mib/oidlib to prtg but the process is easy
