RaumZeitStatus – Statusanzeiger für das RaumZeitLabor

Die Scripts in firebox/ holen vom Etherrape den Raumstatus und mithilfe der Leases-Datei des DHCP-Servers und eines Broadcast-Pings die im Netz befindlichen Geräte, protokollieren beides jeweils in einer RRD-Datei und laden anschließend einen generierten Graphen sowie full.json und simple.txt via WebDAV auf status.raumzeitlabor.de.

Adressen

• status.raumzeitlabor.de/
• api/simple (einfache Textrepräsentation)
• api/full.json (JSON-Datei mit Details)

1. RRD-Datenbanken erstellen:

    rrdtool create status-tuer.rrd -s 60 DS:tuer:GAUGE:120:U:U RRA:LAST:0:1:10080
    rrdtool create status-geraete.rrd -s 60 DS:geraete:GAUGE:120:U:U RRA:LAST:0:1:10080
   

2. MySQL-Datenbank einrichten:

    CREATE TABLE leases (
      `ip` varchar(39) NOT NULL,
      `mac` varchar(17) NOT NULL,
      `ipv4_reachable` tinyint(1) NOT NULL,
      `ipv6_reachable` tinyint(1) NOT NULL,
      `hostname` text,
       PRIMARY KEY  (`ip`)
     ) ENGINE=MyISAM DEFAULT CHARSET=latin1
   

3. davconfig.pm und sqlconfig.pm befüllen

4. Etherrape anschließen

5. raumstatus-meta.sh als Cronjob einrichten
