Different traffic data - vnstat and mailreport



  • Hi Everyone,
    i'm using pfsense 2.2.2 with 9 physical interfaces, one of them is wan the others are used for around 30 vlans.
    We have a public class C network and split it in different blocks for customers.
    Everything works perfect but i got one small anoying problem.
    I'd like to know the montly traffic so i installed vnstat2 package (1.12_3 installed). vnstat looks like it's working fine too.
    To get a montly report by mail i installed mailreport (2.3) and thats where the "problem" is, the traffic data from vnstat and mailreport are different.

    I created one report where every interface is listet like this:
    WAN :: Traffic inverse month previous
    Frequency: monthly
    Day of Week: Saturday (i cant change it to "none", anybody know if this is a problem?)
    Day of Month: 1

    So I get a Report at the beginning of the month that shows the last month traffic.

    I tried it with some different settings but what i get is e.g.:

    WAN
    vnstat:
    June 2015    in 3.43 TB out 2.82 TB total 6.26 TB
    mailreport: 
    June 2015    in 4.08 TB out 3.11 TB

    EM2
    vnstat:
    June 2015    in 25.69 GB out 12.00 GB total 37.69 GB
    mailreport: 
    June 2015    in 26.79 GB out 5.84 GB

    EM3
    vnstat:
    June 2015    in 986.90 GB  out 640.10 GB  total 1.59 TB
    mailreport: 
    June 2015    in 1.02 TB out 655.22 TB

    Anybody got an idea what value is the actual used traffic and how to correct the other one?

    Thanks a lot!
