Also check out http://www.iButton.com/ -> Thermochron.
I've used them on and off for wine-cellar monitoring. Temp only, but can
do alarm based logging, histograms, etc.
Apologies for the long quote, I'm trying to preserve context.

my general approach has been to deploy relativly inexpensive
temperature/humidity logging devices in places where we have "issues", and
have our hvac folks rebalance some of our ac in that direction... in some
cases moving hardware within racks, removing obstructions under our raised
floors adding exhaust fan to racks has all helped with spot tempurature
I can't really recomend a contracter, but I can recomend a temperature
/humidity probe which might be a set in terms of establishing where the
problem areass are...
connects to a serial port has linux and windows drivers requires no
external power, costs $215. I either connect it to a convenient machine or
hang it off a laptop and place it in the location I am concerned about.
picotech also sells 8 channel thermocouple loggers which I haven't played

We have a strange problem (probably with the airflow/vents/arrangements) which
has machines in various locations dying due to heat, when the ambient temp
isn't above 90.
I've tried to find folks to deal with this and I get:
a) Sales Rep's who want me to upgrade the entire system
b) Folks who don't have Data Center experience but are willing to try
c) Folks who claim to have experience but who either won't give ma
references or who's reference don't say nice things about them
I got a line on two places in California (we're in Michigan) as was desperate
enough to call them but both seem to be out of business.
Thanks in advance for any advice and/or recommendations.
