![Temperature Graph](data/t3graph.png)
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.
