Lo sto usando da un mese e funziona davvero bene. C'è da dire che comunque, il software è stato progettato specificatamente per il mio server ma come potete notare, è molto scalabile e adattabile  .
I requisiti sono, programma lm_sensors (sensors) correttamente configurato (editate i " | grep" in poll_* in modo adeguato), sendEmail, una riga da aggiungere in /etc/sudoers se si vuole runnare in da utente e bc (un programma per fare dei calcoli matematici da shell). Facendolo partire senza parametri, stampa il rapporto a video, usando check, fa un controllo del sistema e in caso di problemi manda una mail (i livelli di criticità sono giallo e rosso, quest'ultimo porta allo spegnimento del PC), usando report, manda via mail un rapporto.
| Code: | #!/bin/sh
# Programma che tiene sott'occhio le temperature dei componenti e
# nel caso di problemi non critici (semaforo giallo) manda una mail,
# nel caso di problemi critici (semaforo rosso) manda una mail e spegne
# il computer. Ogni giorno mi manda un rapporto dello stato del sistema
# catturato alle 8.00, alle 12.00 e alle 18.00.
# Nella mail, oltre al rapporto giornaliero sulle temperature, mi faccio
# inviare anche le ultime n righe di messages, dmesg o qualsiasi file io voglia
# Check_temp variables
# CPU limit temperature
cpu_temp_limit=60
# MB limit temperature

Download: Server Control 0.2
deve essere eseguito dalla sua stessa cartella, comunque è anti-idiota, quindi non correte problemi. Se non trova qualche applicazione già installata, basta eseguirlo una volta da root che si arrangia a fare tutto.
