This is a small program to extract some metrics from a Freifunk network. It gathers the data from the JSON file typically used to also populate the Meshviewer map. The data is then made available in a format readable by a Prometheus server.
To compile the tool, first check that you have a recent Go installation (1.14 at the time of this writing). Then clone the repository and run make which will run the tests and compile the binary.
The tool accepts a few parameters, only the --source-url is required:
Usage of freifunk-exporter:
--addr string Address to listen on. (default ":9295")
--cache-interval duration Interval for local caching of Meshviewer data. (default 3m0s)
--source-url string URL to Meshviewer JSON file.
So, for example to get the metrics for Freifunk Bodensee run:
freifunk-exporter --source-url https://meta.ffbsee.net/data/meshviewer.json
