Per IP Traffic accounting

eightiescalling · Sep 5, 2021

Out of curiosity, what's behind the need for real time data? Beyond data points in influx and graphs what do you need the data real time for?

Just wondering whether there may be other ways to achieve the end goal.

ok. good approach.

I am testing integrations at home environment. Sometimes IPTV services , sometimes other services.
For example testing an IPTV service on several devices (Samsung TV, LG TV, Android TV , mobile device etc.) , I need to find which device used how much bandwidth.
With my old router (AC88U) , I was able to get iptables accounting data per 2 or 5 minutes and then calculate average bandwidth usage from there.
Now this is not possible.
Traffic Analyzer just saves the total used TX RX per session , at the end of the session. We can of course calculate a bits/sec data from that total session but start and end of the session (incline/decline) will make it not usable.
Of course for this specific reason, I can collect data using tcpdump and then post process.
But it is not as easy as recording all data with accounting.

For the fancy part; I really love telling my visitors "you are now using X of my bandwidth"

You may be able to use this crude monitoring script

There was a query recently about how to detect DOWNLOAD throughput activity and BLOCK the device if deemed appropriate so I have revised my suggested solution. Using the Traffic Analyzer reports, you can review device activity, but real-time monitoring may be useful. So here is my shoddy...

thanks. but I could not figure out how to use this script.
in fact, I believe it is not even compatible with current firmware.

Because I get the following error:

Code:

admin@RT-AX88U-21C1:/jffs/scripts# ./QuotaMonitor.sh   init    ip=XEON-POWER

 v1.04 Quota Monitoring.....

        Quota Monitoring Setup complete.

./QuotaMonitor.sh: line 1: ExpandIPRange: not found

so it is looking for a "ExpandIPRange" command but that is not available.
any ideas ?

I just tried this as you recommended. However it did not change anything.
in any case, this "ExpandIPRange" seems to be a command. it is not available on my environment (ax88u with merlin firmware)

any other ideas ?

The problem is because the script is trying check whether "XEON-POWER" is a range or a name and the ExpandIPRange function is missing.

OK, good to know.

EDIT: Some of my early scripts accepted a range of IPs as arguments, but this script was never tested to accept a group range of IPs on the commandline denoted by '-' without the group file '/jffs/configs/IPGroups' existing.

e.g. you can see that normally on my router the initialisation request fails gracefully because '/jffs/configs/IPGroups' currently exists (for use by my other scripts), but does not have the perceived range XEON-POWER defined.

However if I delete '/jffs/configs/IPGroups' and request the script again then the script does indeed panic

....... (until I reinstate the file)

You can temporarily try manually creating an empty 'IPGroups' file

Code:

touch /jffs/configs/IPGroups

to see if the script will now initialise until I can post a patched/tested version of the script (that has been unaltered on GitHub for nearly 2 1/2 years!) that either removes the reference to function ExpandIPRange() or includes it.

NOTE: The script may still fail/show inaccurate metrics if Hardware Acceleration is ENABLED.
