Detta är ett litet program skrivit i perl till MRTG för att via SNMP hämta information från en NETGEAR ReadyNAS NV+ som sedan MRTG kan rita snygga grafer.

Det som den kan hämta är Temperaturen i lådan, Fläktens varvtal, volymens storlek, hur mycket som är fritt på volymen och dom enskilda diskarnas temperatur.

Programmet kan man hämta här: mrtg_readynas-1.0.tar.gz

Så här ser min konfiguration för MRTG ut:
