Yet another node info collector
yanic is a respondd client that fetches, stores and publishes information about a Freifunk network. The goals:
- Generating JSON for Meshviewer
- Storing statistics in InfluxDB or Graphite to be analyzed by Grafana
- Provide a little webserver for a standalone installation with a meshviewer
How it works
In the first step Yanic sends a multicast message to the group ff02:0:0:0:0:0:2:1001 and port 1001.
Recently seen nodes that does not reply are requested via a unicast message.
