fritzbox-munin

A collection of munin plugins to monitor your AVM FRITZ!Box router. The scripts have been developed using a FRITZ!Box 7490(Amazon link) running FRITZ!OS 07.12.

If you are using the scripts on a different Fritz!Box model please let me know by

Introduction

These python scripts are Munin plugins for monitoring the Fritz!Box router by AVM.

fritzbox_traffic

fritzbox_traffic shows you the traffic of the WAN interface (requires fritzconnection)

If you do not want to show the interface maximum values, add the following to your plugin-configuration:

env.traffic_remove_max true

fritzbox_connection_uptime

fritzbox_connection_uptime shows you the connection uptime in days (requires fritzconnection)

fritzbox_cpu_usage

fritzbox_cpu_usage shows you the cpu usage (requires password)

fritzbox_cpu_temperature

fritzbox_cpu_temperature shows you the cpu temperature (requires password)

fritzbox_memory_usage

fritzbox_memory_usage shows you the memory usage (requires password)

fritzbox_power_consumption

fritzbox_power_consumption shows you the power consumption (requires password)

fritzbox_uptime

fritzbox_uptime shows you the uptime in days (requires password) (language dependant, see below).

fritzbox_wifi_devices

fritzbox_wifi_devices shows you the number of connected wifi clients (requires password) (language dependant, see below).

Installation & Configuration

1. Pre-requesites for the fritzbox_traffic and fritzbox_uptime plugins are the fritzconnection and requests package. To install it

    pip install fritzconnection
    pip install lxml
   

2. Make sure the FritzBox has UPnP status information enabled. (German interface: Heimnetz > Heimnetzübersicht > Netzwerkeinstellungen > Statusinformationen über UPnP übertragen)

3. Copy all the scripts (*.py) to /usr/share/munin/plugins

4. Make all the scripts execute able (chmod 755 /usr/share/munin/plugins.*py)

5. Create entry in /etc/munin/plugin-conf.d/munin-node:

   1. only one fritzbox or all fritzboxes use the same password:

      [fritzbox_*]
         env.fritzbox_password <fritzbox_password>
         env.traffic_remove_max true # if you do not want the possible max values
      

   2. multiple fritzboxes:

      [fritzbox_<fqdn1>_*]
        env.fritzbox_password <fritzbox_password>
        env.traffic_remove_max true # if you do not want the possible max values
      
      [fritzbox_<fqdn2>_*]
        env.fritzbox_password <fritzbox_password>
        env.traffic_remove_max true # if you do not want the possible max values
      

6. Create symbolic link in /etc/munin/plugins for fritzbox_helper.py.

   cd /etc/munin/plugins
   ln -d /usr/share/munin/plugins/fritzbox_helper.py fritzbox_helper.py
   

7. Create symbolic link in /etc/munin/plugins for probes.

   link `/usr/share/munin/plugins/fritzbox__<probe>.py` to `fritzbox_<fqdn>_<probe>`
   
   example
     cd /etc/munin/plugins
     ln -d /usr/share/munin/plugins/fritzbox__cpu_usage.py fritzbox_fritz.box_cpu_usage
     ln -d /usr/share/munin/plugins/fritzbox__cpu_temperature.py fritzbox_fritz.box_cpu_temperature  
     ...
   
   if you have multiple fritz box just create multiple sets of links with a different fqdn or ip.
   
   example
     cd /etc/munin/plugins
     ln -d /usr/share/munin/plugins/fritzbox__cpu_usage.py fritzbox_fritz.box_cpu_usage
     ln -d /usr/share/munin/plugins/fritzbox__cpu_usage.py fritzbox_box2.fritz.box_cpu_usage
     ln -d /usr/share/munin/plugins/fritzbox__cpu_usage.py fritzbox_192.168.100.1_cpu_usage
     ln -d /usr/share/munin/plugins/fritzbox__cpu_temperature.py fritzbox_box2.fritz.box_cpu_temperature  
     ln -d /usr/share/munin/plugins/fritzbox__cpu_temperature.py fritzbox_box2.fritz.box_cpu_temperature  
     ln -d /usr/share/munin/plugins/fritzbox__cpu_temperature.py fritzbox_192.168.100.1_cpu_temperature  
     ...
   

8. Restart the munin-node daemon: systemctl restart munin-node.

9. Done. You should now start to see the charts on the Munin pages.

Localization

Two scripts depend on the language selected in your fritzbox: the uptime and wifi_devices. Currently, two locales are supported:

1. German: de (default)
2. English: en

You can change the used locale by setting an environment variable in your plugin configuration:

env.locale en

Set a group for your fritzboxes

You can group the graphs of your fritzbox:

1. Use the following as your host configuration in /etc/munin/munin.conf or by creating a file in /etc/munin/munin-conf.d

    [<groupname>;<fqdn>]
        address 127.0.0.1
        use_node_name no
   
    example:
    [Network;fritz.box]
        address 127.0.0.1
        use_node_name no
   

2. Restart your munin-node: systemctl restart munin-node

Environment Settings

Do not forget to restart the munin-node daemon as described in step 3 of the installation instructions above.
