Traffic graph reports double the real amount on some interfaces.

bill_mcgonigle

I stumbled onto this while setting up a limiter. Attaching a screenshot of the traffic graphs. Notice that the Guest interface is showing double the Fairpoint interface; VLANs 6 and 4 respectively on em0. I have the debug menu turned on on this Roku device and it also senses a 1.5MB network (the limiter value, accurate on the Fairpoint interface).

The directions would be reversed between the two, but I did a line-saturation upload on the Fairpoint interface and the 'Out' value is correct there. That's the interface with the current gateway (top tier in the gateway group).

Same issue VLANs interfaces traffic is double, i was also thinking about configuration i might configure wrong. any one has nay idea why pfsense behave like that is its a bug.

Heliborn

I am having an identical issue. Has any one found any information regarding this?

Thanks,

Hi,

I have same problem … here

Rezin

Affected here too.

v2.1-RELEASE (i386).
Running in an ESXi 5.1 VM, using VMXNET 3 vNICs (vmx3f#).
There are no VLANs configured in pfSense directly, but some vNICs use vSwitches that have a VLAN tag.

@ab0tj:

OK, an update on this one. All the VLAN interfaces show double the amount of "out" traffic and are accurate on the "in" traffic.

Mine's the opposite - 'in' is being doubled, while 'out' is fine.

For now, I've changed the line in /usr/local/www/graph.php to:

var ifin = parseInt(t[1]/2, 10);    // number of bytes received by the interface

… in the below code block:

var t = obj.content.split("|");
var ugmt = parseFloat(t[0]);  // ugmt is an unixtimestamp style
var ifin = parseInt(t[1], 10);    // number of bytes received by the interface
var ifout = parseInt(t[2], 10);   // number of bytes sent by the interface
var scale;

There might be a better/correct bandaid, but that'll do for the minute.

Just to say I'm also seeing this.

2.1.2 amd64 on an Intel 2500CC platform with no Vlans.

If I look at my traffic graphs for WAN and LAN then the 'in' of both is correct, but the 'out' of both is exactly double what it should be.

Riroxi

Same here. No vlans, 2.1.2 amd64 em0 card.

WAN card is correct, LAN card is double on out values.

Hey

Same here. Using BLKD2500CCE, no VLANs.

Any other ideas instead of edit graph.php?

Bandwidthd and Vnstat2 also shows double amount of traffic on lan interface.

I also have this issue. This has been discussed several times, see for example this https://forum.pfsense.org/index.php?topic=75343.0..

Probably this is a known error (https://redmine.pfsense.org/issues/3314). It seems that the error lies in the OS and developers discuss that this might be fixed with the upcoming version 2.2.

Same issue here using the built-in ethernet ports on our super micro server - LAN shows twice out traffic as WAN in traffic. No VLANs.

Also seeing this problem - testing upload bandwidth with iperf, the wan graph is showing double the outgoing traffic that the lan graph is showing coming in.

I'm seeing this exact issue in the latest 2.2 snapshots (screenshot attached). It also seems to be directional: when I send traffic from a server in my DMZ to a machine on my LAN, the DMZ registers the correct level but the LAN doubles he traffic. When I send traffic in the reverse direction, the opposite occurs (again, see screenshot below).

The server in my DMZ is running off a 2-port LACP connection, and both networks are using VLANs (which seems to be the factor that causes the issue).

Looks like the redmine bug has already been updated to reflect the fact that this isn't fixed in 2.2, but FYI.

Not having this issue in 2.1.4 just for info.

Didn't you uncheck the box "Get a free copy of your private data in the iCloud" ;D :P

mtomczyk

I am seeing the same thing on my system. I am not using VLAN's at all. I am on Version 2.1.5 and my hardware is NetGate. If I look at the RRD graphs everything is accurate. It is only on the Traffic Graphs.

Thanks

mpi

Also seeing this on 2.1.5 on an Atom D510 based system with onboard LAN (em1) and WAN (em0) ports for an traffic on the OUT of a port. Specifically, when running a speedtest via speedtest.net:

On the download test, the IN on WAN shows a match to the speedtest while the OUT on LAN shows double.

During the upload test, the IN on LAN shows matching speed while OUT on WAN shows double.

Screen grabs of speediest and bandwidth graphs attached.

No it's not. At least not the only cause. There are several reports in this thread alone that state they are not using VLANs…

Maybe we can find a pattern if we start to give more detailed info of the affected (and non-affected) interface combinations?
pfSense: 2.1.5-RELEASE (amd64) (and 2.1.4-RELEASE (amd64) and 2.1.3-RELEASE (amd64))
WAN: Intel 82579L (on Intel DQ77KB)
LAN: Intel 82579LM (on Intel DQ77KB)
VLAN: No
Symptom: outgoing traffic reported 2x in both directions (upload and download)

It's a known bug in the underlying FreeBSD.

@Derelict:

It's a known bug in the underlying FreeBSD.

Can you give a link to the bug?
It would be good to fix up little crud like this. It puts off people new to pfSense when something like the traffic graph shows an obviously wrong figure.
