Traffic Stats - Which to believe?

[CaptnDanLKW]

I love my data and stats but I'm not sure which to believe.
The Data in Traffic Monitor (Merlin's Enhancement) or Traffic Analyzer - Statistics (Part of Trends DPI engine)

Traffic Analyzer:

or Traffic Analyzer - Statistics:

Router is an RT-AC86U on 384.17. I have QOS Disabled, so Runner and FA acceleration are enabled. I remember from the AC68U and N66U days that the CTF / HW Acceleration could skew the stats in Traffic Monitor because the bits bypass iptables... or something like that.

So, which do I believe?

Neither.

Compare with your ISP data, you'll see.

At first glance, your Traffic Monitor data is twice that of your Traffic Analyzer.

Did you ever get to the bottom of this, Dan?

I've just noticed the same is true for me, using July 1-8 as the comparison (we've been away from the house, so data usage is low):

And the same in analyzer:

More or less double. Not that I trust my ISPs data monitoring (8.93GB at time of writing, but won't have accounted for today's usage yet), but it's a lot closer to the Analyzer numbers, than the Monitor numbers. For reference in June 2020, Monitor showed 573GB, Analyzer showed ~518GB, and my ISP showed 439GB.

I have QoS enabled, set as adaptive, and strangely HW acceleration is enabled for both runner, and flow cache - i assumed having QoS enabled, would set those to disabled.

Thanks!

In short - no. I never got a clear answer in this thread nor a lot of other searching. I think the variables (models, QOS types, HW accel (two types), per-IP monitoring, make it difficult for a single clear answer why, I just wish I knew how things worked under the hood so I could do real time checking.

That said, as of 6/1 I decided to start over with all my trend data (did not re-init my tomato stats). Turned off all the trend stuff (shut everything off, removed all the .db files), and re-enabled. That was with 384.17 (and now 384.18). and my Traffic Status / Traffic Analyzer values about the same... +/-.

No other changes - Still an AC86U Primary Mesh + 1 AC86U Node, QOS has been off, per-ip monitoring off. That means Runner and FC HW accel are both enabled.

So I don't know what happened or why things have evened out but I'll keep my eye on it.

My fuzzy memory tells me that per-IP monitoring and 'traditional' QOS are the two likely culprits that usually cause inaccurate counters but YMMV.

per-IP monitoring is not present on the HND routers as it is incompatible.

Well I'll be darned - just assumed it was there and I never enabled it. Observation noted. +1

 

[Morpheus2020]

Same problem. Traffic Monitor data is twice that of Traffic Analyzer (or add all classifications in Adaptive QoS).
My router is RT-AX86U running Asuswrt-Merlin 388.8.2 and FlexQoS 1.3.4. Flow Cache and Runner are disabled via SSH.

Have you found the cause of the problem?

never checked until today router say 980GB this month sounds low , I'm on unlimited data so don't really care .
