Traffic graph reports double the real amount on some interfaces.

And I thought it was my messed up config…

I can confirm this on vge interfaces with VLANs on top.
Using 2.1 on nanobsd (4g).

Disturbed1

same double the bandwidth,
this really sucks when i use that to monitor user traffic

running installed iso on physical machine, used pfsense updater…

Nice to hear I'm at least not alone on this one. I'll report back if I manage to find a fix. Thanks guys.

Just as a follow up - I see the same behaviour on an ALIX board when using VLANs.
It seems to be independent of the interface type (VR on ALIX) and occurs with virtual interfaces only.

I'll try to point the developers to it.

I see the same issue here. I also noted that shaper queue status is wrong/too high, sometimes WAY off (i.e. a vlan with 3mbps MAX available from WAN showing 24mbps out to LAN).

I noted this RRD issue in the previous 2.x version as well, but it has gotten much worse and spread to queue status in 2.1

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.

elel

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.
