Yet another node info collector

Build Status Coverage Status Go Report Card

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.

Documentation

Quick startup

Usage

Usage of ./yanic:
