Logs which devices are in your local network and draws graphs

Screenshot:

1. add this line to your crontab on your raspberry pi (or other device that is always on):

   */10 * * * * nmap -sn $subnet -oX - >> $outputpath/logs

   or

   */10 * * * * nmap -sn $subnet -oX - | xz >> $outputpath/logs.xz

   if you don't have a lot of space on that device.

   • $subnet is your local network, e.g. '192.168.178.*'
   • $outputpath is the path where you want your log stored

2. create a config.json file. For the schema see Configuration.ts

   minimal example:

   {
   	"input": "../logs",
   	"macToName": {},
   	"hostToName": {},
   	"logInterval": 10,
   	"ignoreLessThan": 3000,
   	"self": "raspberry-hostname"
   }

3. Open index.html in a browser. Firefox should directly work, for Chrome you need to open it via a server (like python3 -m http.server) because of security reasons.
