A Munin plugin for monitoring the susv
This plugin fetches the voltage and current from input and battery and the battery capacity and visualizes them in munin graphs.
I put this together without knowing a thing about python programming or munin plugin programming so keep that in mind when you stumble over the numerous errors and design mistakes I've certainly made ;)
First you should clone the repository with
git clone https://github.com/TWfromSWD/susv_munin_plugin.git
You'll end up with directory called susv_munin_plugin containing this file and the plugin Python script named susv_
For the plugin to work you'll need python and the susv client software installed.
The Plugin needs to be copied into the munin plugin directory which should be
/usr/share/munin/plugins/
on the Raspberry Pi.
Also the plugin's configuration needs to be added to
/etc/munin/plugin-conf.d/munin-node
[susv*]
user root
group root
This plugin is enabled for automatic installation by munin-node-configure so after you followed the above steps you just need to run
sudo munin-node-configure --shell to get the shell code for creating the needed symlinks. Or you can just pipe that output directly to the shell by running
sudo /usr/sbin/munin-node-configure --shell | sudo sh in the /etc/munin/plugins directory.
Either way you should end up with this additional symlinks:
lrwxrwxrwx 1 root root 30 Apr 17 14:03 susv_battery -> /usr/share/munin/plugins/susv_
lrwxrwxrwx 1 root root 30 Apr 17 14:03 susv_currents -> /usr/share/munin/plugins/susv_
lrwxrwxrwx 1 root root 30 Apr 17 14:03 susv_voltages -> /usr/share/munin/plugins/susv_
Now you just need to restart the munin-node by typing
sudo service munin-node restart
and the graphs should start showing up in the next cycle.
