B/W Distribution Usage versus Bandwidth Usage report by ISP

[AndyHiggins]

I am struggling trying to figure out what is happening as the data usage reported by the ISP is significantly higher than that as reported by the total data usage in the B/W Distribution section of the Gargoyle router. I am reasonably certain of the following:

[*] The time zones for the stats reported by the ISP and the Gargoyle router are the same.
[*] All Internet usage is going via the Gargoyle router (either via one of the physical ports or wifi) i.e. there is nothing "stealing" the bandwidth upstream of the Gargoyle router.

Broken down by the hour there are some cases where e.g. Gargoyle indicates a total of 60Mb of data being used across all devices connected to the router and the ISP reports that 400Mb was used over the same period.

Is there anything I could be missing? Any suggestions would be appreciated. I am running an older (1.6.1) version of Gargoyle (but cannot upgrade right now due to logistical complications).

Sounds a little like you might be comparing bits with bytes?

I did check that and I don't believe it is the case (both report in Mbs). It is not consistently off to that extent so I believe something else is up (some times they are a lot closer to each).

For example for a particular hour slot the ISP reported the following. The first data amount (325.44 MB) is the download and the second is the upload (9.81 MB) data:

02/27/2016 11:00:00 12:00:00 60 325.44 MB No 9.81 MB

For this same hour Gargoyle reported a total usage of 71.804 MBytes

So I believe I am supposedly "comparing apples with apples"

Are you able to provide a screen shot of both data sets please?
Make sure you blank out any sensitive information that may be on your ISP page.

You'll need to use an external host like imgur as the forum uploader is full.

Here is a screenshot of the relevant information from the ISP:



And from the Gargoyle B/W Distribution screen filtered for the hour of 11am to 12pm (today):



I should also mention this is in a remote location and the source of the bandwidth is via a satellite connection i.e. it is very expense and hence the need to manage it carefully (every Mb is precious ).

Can I also see the similar table from the BW Usage page. It should be the same as the other but worth looking as well.
Thanks.

For some reason on the Bandwidth Usage page it is only showing 2 hours and not stats for every hour of the day when on the hour scale i.e.



It does however seem to show more complete information when on the "day" scale:



I did however change configuration and reboot a number of times today (this problem I am tying to solve has been going on for a few weeks now).

Out of interest, taking it to a daily level, the ISP is reporting a total of more than 2Gb usage whereas you can see above that Gargoyle is reporting just over 1.1Gb of total usage for the day.

I am wondering if there are weather events at the satellite uplink or downlink that are dropping packets that the ISP base-station sees but Gargoyle never does. Not very helpful

I did some more tests today. Going out on a bit of a limb here (I could be completely wrong) but I suspect when quotas are set and the limit of those quotas are reached with throttling enabled (i.e. not set to shutdown Internet access once the quota has been reached but instead to throttle the connection), the data usage from the throttled device is not being counted (or at least is not counted properly) in the Gargoyle B/W Distribution report (from after the quota has been reached).

Is this possible (I am using version 1.6.1 so it could have been fixed since then)?
