How to install YAMon on Asuswrt-Merlin ?

[letgoodgrow]

Hello,

I've been searching for a reliable bandwidth monitoring solution, but nothing seems to work.
I'm not sure if the issues are due to limitations imposed by Asus or if the available scripts are just outdated.
Has anyone managed to get a script like that to work effectively?
I've encountered endless loop of errors while trying to install them.
Any help would be appreciated.

On what router? What firmware release?

Have you tried installing dn-vnstat after typing "amtm" within SSH?

vnStat - [Release] vnStat-on-Merlin - UI, CLI and email - data use and data limit monitoring - R1 and R2

vnStat-on-Merlin - Release versions - R1 and R2 Update 18 July 2021: Upgrade! For ARM and AARCH-based routers, we've got some great news: vnStat-on-Merlin Release 2 (R2) is now available for non-MIPS devices. This version is based on vnStat 2.7, recently included as an Entware package. More...

Seemed to generally work for me when I tested it not long ago, and mounts a nice WebUI page for the stats.
Not sure what your goal is other than monitoring bandwidth, I saw there was also a Quota Monitoring script from Martineau here: https://www.snbforums.com/threads/edit-real-time-quota-monitoring-download-upload-data-used.50066/

thanks for sharing
| like the built in Traffic Analyzer Stats but its data get wiped randomly and it only show top 5 devices which isn't practical
YAMon shows missing files like setup.sh

I believe that the vnstat script uses vnstatd from Entware, and works independently of the built-in traffic Analyzer:

This is an implementation of vnStat for use on AsusWRT-Merlin routers. This effort was started to enable accurate measurement of data use in a local database (for privacy reasons), and as an alternative the internal monitoring tool, Traffic Analyzer > Traffic Monitor, which will periodically record false “17GB” usage bursts.

YAMon shows missing files like setup.sh

vnstat does not show stats like devices etc..
a part from that, I tried to install bwmon


I installed Entware through "AMTM"
then followed all the steps here

nice that one shows results, thanks for help
next: I tried
netstat -tuln | grep lighttpd
no results, ai says it means means Lighttpd isn’t listening on any port
so we made
lighttpd.conf and filled with some data inlucde the port 8081
and tried to start
killall lighttpd 2>/dev/null
lighttpd -m /opt/lib/lighttpd -f /opt/etc/lighttpd/lighttpd.conf
but failed

Your problem is the installer for bwmon is not completing.
I am assuming your only getting this far when trying to install:

Instead of this:

Which is why I mentioned to include any messages your getting and any screenshots.

To fix it, modify the install.sh at this location:

/mnt/USBNAME/bwmon/server

Open the install.sh and modify this code at line 38 :

bc -v > /dev/null 2>&1
if [ $? -ne 0 ]; then
    echo "Installing bc ..."
    opkg install bc
else
    echo "bc is installed"
fi

To this:

if ! bc -v >/dev/null 2>&1; then
    echo "Installing bc ..."
    opkg install bc
else
    echo "bc is installed"
fi

And the install will complete.
