README

micro-daemon is a respond daemon to fetch information for Freifunk Nodes and represent this information with Websocket- and JSON-APIs.

Issues/Features in the Future

It will also APIs for manipulate the fetched data and give a access for ansible to push changes to the nodes.

Also it's will push statistic informations to a influxdb.

Usage

Usage of ./micro-daemon:
  -collectInterval int
    	interval for data collections (default 15)
  -host string
    	path aliases.json file
  -httpdir string
    	a implemented static file webserver (default "webroot")
  -path-aliases string
    	path aliases.json file (default "webroot/aliases.json")
  -path-nodes string
    	path nodes.json file (default "webroot/nodes.json")
  -port string
    	path aliases.json file (default "8080")
  -saveInterval int
    	interval for data saving (default 60)

Development

respond

It send the gluon-neighbour-info request and collect them together.

It will send UDP packetes by the multicast group ff02:0:0:0:0:0:2:1001 and port 1001.

modes.Nodes

It cached the Informations of the Nodes and will save them periodical to a JSON file. The current nodes are saved default under nodes.json.

websocketserver

One Instance is running under /nodes which send updates or new Nodes, which are collected by respond.

Issues

Later there should be also /aliases Websocket with Authentification to manage the aliases.json with the request for changes.

A Implementation of the connection to influxdb are also needed, maybe log a little bit to telegraf from influxdb.
