This graph shows the machine room temperature over the last several days.
We have installed a TempTrax 2000 in our machine room to monitor the temperature and alert us if it goes outside pre-set bounds.
The probe has a rs232 interface and uses a simple and well-documented protocol. We wrote a simple daemon, tempd.c, that samples the temperature every 10 minutes, and makes an entry in /var/log/templog:
1049914980 72.7 1049914985 73.3 1049915005 71.5
The first number is the time in seconds from the Unix epoch, the second is the temperature.
This graph shows machine room temperature
from April 2003, with some gaps.
