`yanic` is a respondd client that fetches, stores and publishes information about a Freifunk network. The goals:
|
2017-01-30 14:23:36 +00:00
|
|
|
* Generating JSON for [Meshviewer](https://github.com/ffrgb/meshviewer)
|
2016-03-12 15:40:43 +00:00
|
|
|
* Storing statistics in [InfluxDB](https://influxdata.com/) to be analyzed by [Grafana](http://grafana.org/)
|
2017-01-30 14:23:36 +00:00
|
|
|
* Provide a little webserver for a standalone installation with a meshviewer

|
|
|
|
* [meshviewer](https://map.bremen.freifunk.net) **Freifunk Bremen** with a patch to show state-version of `nodes.json`
|
|
|
|
|
* [grafana](https://grafana.bremen.freifunk.net) **Freifunk Bremen** show data of InfluxDB

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.
