Hey, I have set up a Docker container with the following parameters:

version: '3.8'
services:
  fritzbox-bandwidth-monitor:
    image: thkukuk/fritzbox-bandwidth-monitor
    container_name: fritzbox-bandwidth-monitor
    ports:
      - "2080:80"
    volumes:
      - /home/root/fritzbox-bandwidth-monitor:/data
      - /home/root/fritzbox-bandwidth-monitor:/srv/www/htdocs
    environment:
      - TZ=Europe/Berlin
      - DEBUG=1
      - FRITZBOX_NR=6490
      - FRITZBOX=192.168.200.1
      - MAX_DOWNLOAD_BYTES=32500000
      - MAX_UPLOAD_BYTES=7500000
      - POLL_INTERVAL=30

After starting, graphs are not updating, max upload and download are not recognized.

The log says following:

Used hardware: FRITZ!Box 6490 Cable FRITZ!OS: 7.57

Any idea what `I´m doing wrong?

the reason for the top of the page not updating is, that the corresponding fields in the mrtg.cfg are not updated:

bash-5.2#

the entrypoint.sh script updates the values in the config generally, but not the "top of the page" part:

bash-5.2# cat entrypoint.sh
#!/bin/sh
[...]
POLL_INTERVAL=${POLL_INTERVAL:-300}
MAX_DOWNLOAD_BYTES=${MAX_DOWNLOAD_BYTES:-16000000000}
MAX_UPLOAD_BYTES=${MAX_UPLOAD_BYTES:-5300000000}
FRITZBOX_NR=${FRITZBOX_NR:-7530}
FRITZBOX=${FRITZBOX:-192.168.178.1}
RUN_WEBSERVER=${RUN_WEBSERVER:-1}
[...]
if [ ! -f /etc/mrtg.cfg ]; then
    sed -e "s|7490|${FRITZBOX_NR}|g" \
        -e "s|^MaxBytes1\[fritzbox\]:.*|MaxBytes1\[fritzbox\]: ${MAX_DOWNLOAD_BYTES}|g" \
        -e "s|^MaxBytes2\[fritzbox\]:.*|MaxBytes2\[fritzbox\]: ${MAX_UPLOAD_BYTES}|g" \
        -e "s|192.168.178.1 (fritzbox.home.lan)|${FRITZBOX}|g" \
        /fritzbox-bandwidth-monitor/mrtg.cfg > /etc/mrtg.cfg
fi
[...]
bash-5.2#

so it's probably neccessary to add 2 more lines to the sed part in the entrypoint.sh that replaces those values (and calculates them first obv).

EDIT: in entrypoint.sh replace

MAX_DOWNLOAD_BYTES=${MAX_DOWNLOAD_BYTES:-16000000000}
MAX_UPLOAD_BYTES=${MAX_UPLOAD_BYTES:-5300000000}

with

MAX_DOWNLOAD_BYTES=${MAX_DOWNLOAD_BYTES:-16000000000}
MAX_UPLOAD_BYTES=${MAX_UPLOAD_BYTES:-5300000000}
MAX_DOWNLOAD_BIT=$((MAX_DOWNLOAD_BYTES / 125))
MAX_UPLOAD_BIT=$((MAX_UPLOAD_BYTES / 125))

and

if [ ! -f /etc/mrtg.cfg ]; then
    sed -e "s|7490|${FRITZBOX_NR}|g" \
        -e "s|^MaxBytes1\[fritzbox\]:.*|MaxBytes1\[fritzbox\]: ${MAX_DOWNLOAD_BYTES}|g" \
        -e "s|^MaxBytes2\[fritzbox\]:.*|MaxBytes2\[fritzbox\]: ${MAX_UPLOAD_BYTES}|g" \
        -e "s|192.168.178.1 (fritzbox.home.lan)|${FRITZBOX}|g" \
        /fritzbox-bandwidth-monitor/mrtg.cfg > /etc/mrtg.cfg
fi

with

if [ ! -f /etc/mrtg.cfg ]; then
    sed -e "s|7490|${FRITZBOX_NR}|g" \
        -e "s|^MaxBytes1\[fritzbox\]:.*|MaxBytes1\[fritzbox\]: ${MAX_DOWNLOAD_BYTES}|g" \
        -e "s|^MaxBytes2\[fritzbox\]:.*|MaxBytes2\[fritzbox\]: ${MAX_UPLOAD_BYTES}|g" \
        -e "s|<td>16000 kbit/s</td>|<td>${MAX_DOWNLOAD_BIT} kbit/s</td>|g" \
        -e "s|<td>1024 kbit/s</td>|<td>${MAX_UPLOAD_BIT} kbit/s</td>|g" \
        -e "s|192.168.178.1 (fritzbox.home.lan)|${FRITZBOX}|g" \
        /fritzbox-bandwidth-monitor/mrtg.cfg > /etc/mrtg.cfg
fi

this will at least fix the top of the page numbers. image
