We have our Interfaces on our Cisco ASA's being monitored on PRTG, and our ASA and packitshaper seem to report accurate speeds, but the PRTG isn't anywhere close on the bandwidth monitoring. Any thoughts?

NetFlow or SNMP? If SNMP, what results do you get if you query the same OIDs used by the sensors with our SNMP Tester? Do the values differ to those provided by PRTG? If NetFlow, have you had a look at HowTo: Monitoring Cisco ASA Firewalls with PRTG using Netflow 9?

I get this on the SNMP tester: Test 15:Outside Interface: in=131175396465 out=34567937728.

According to our tests, we should see around 41Mbs. PRTG only reads out 10 to 15 in either direction.

Am I just missing something?

That's the values the device is returning, I'm afraid. In order to discern if there is an issue I would suggest forwarding us a mail to [email protected], with reference to this thread, seeing as we will require configuration data you might not want to present publicly.
