I´m reading the bandwith information on my ASA 5510 8.2.(5) outside interface with snmp and when I take historical data for the last 24 hours I see a total volume of 7.6Gb.
I also send netflow (9) data from my ASA to PRTG with a ACL ANY ANY IP, so it covers all interfaces and all traffic. Looking at historical data for the last 24 hours within the same periode I only see total volume of 3.7Gb.
PRTG is version: PRTG Network Monitor 22.214.171.12493
Why do I see nearly a double in traffic with snmp?
