Hi all
I have written a plugin to log various data to Graphite. Once the data is logged in Graphite, you can use something such as Grafana to produce some nice graphs and dashboards :
You can find the plugin at: https://github.com/jh71283/IndigoGreenSkyDataLogger
... To log a variable to Graphite, simply put it into a folder called Graphite. All variables in here will be sampled once a second and sent to Graphite. It's that simple!
