Upload/Download Counters reset every 4GB

[detlevo]

The total upload and download counters are reset to 0 whenever they reach 4GB. What can be done about this?

[tillepille]

This is a problem of the fritzbox API.
The counter resets, the closest I got was 4289894889 bytes. Which is conspiciously close to an uint32.
But what I can see at my 6490 is a parameter called NewX_AVM_DE_TotalBytesReceived64 which seems to be a more reasonable value since boot.

@mxschmitt I do not get how the parsing of the SOAP response exactly works, For me the corresponding field for gateway_wan_bytes_received is named NewTotalBytesReceived but I don't see this keyword anywhere in the code.
Maybe you can help out?

He uses the Action GetAddonInfos which is described in the pdf

fritzbox_exporter/cmd/exporter/exporter.go

Lines 79 to 80 in b852685

	Action: "GetAddonInfos",
	Result: "TotalBytesReceived",

I think you are probably right with your assumption about using NewX_AVM_DE_TotalBytesReceived64 - the corrospondending variable would be X_AVM_DE_TotalBytesReceived64

The same goes for

fritzbox_exporter/cmd/exporter/exporter.go

Lines 91 to 92 in b852685

	Action: "GetAddonInfos",
	Result: "TotalBytesSent",

which should probably be X_AVM_DE_TotalBytesSent64

I tried your updated image and it's not working for me - metrics say 0 for the received and sent values

gateway_wan_bytes_receive_rate{gateway="fritz.box"} 118485
gateway_wan_bytes_received{gateway="fritz.box"} 0
gateway_wan_bytes_send_rate{gateway="fritz.box"} 13387
gateway_wan_bytes_sent{gateway="fritz.box"} 0
gateway_wan_connection_status{gateway="fritz.box"} 1
gateway_wan_connection_uptime_seconds{gateway="fritz.box"} 52596
gateway_wan_layer1_downstream_max_bitrate{gateway="fritz.box"} 2.85305e+08
gateway_wan_layer1_link_status{gateway="fritz.box"} 1
gateway_wan_layer1_upstream_max_bitrate{gateway="fritz.box"} 4.441e+07
gateway_wan_packets_received{gateway="fritz.box"} 1.209051e+06
gateway_wan_packets_sent{gateway="fritz.box"} 5.960714e+06

Is this only happening for me?
I thought of some possibilities why this would happen:

1. documentation is obsolete (says it's for fritz os 6.93 but i'm using the most recent version)
2. we need to change something else too
3. some unique error on my side

Buuuuut
IDK
After querying the upnp interface i got following output which seems like my PR should have been correct

Small update
I build the binary on my client and with this binary i get non zero values for X_AVM_DE_TotalBytesSent64 and X_AVM_DE_TotalBytesReceived64

Can somebody verify if the docker container is working for them?

Edit: correct the values to the right ones - accidentially used the prometheus ones ;)

[mxschmitt]

I will revert the last commit. a7c9b2a

Should be fixed on DockerHub in a few minutes.
