Hobbit compatible temperature monitor
I am looking to add temperature graphs to hobbit.
What should I use to monitor and graph the temperature of our server room? None of our servers report any temperature readings in the client data. We have some APC battery backups that have environmental monitors built in, but I am willing to spend a little cash on a separate device if there is something proven to work with Hobbit.
Thanks,

We use ITWatchdogs Weathergoose. I poll them with mrtg, and inject status information into hobbit using bbmrtg.pl

What servers are these? Any recent HP or Dell servers, if you have their respective agents (HPASM or OMSA) installed, should allow you to monitor their temperatures via snmp, e.g. with Devmon + Hobbit you should be able to get graphs for each temperature probe.

Can you get the temperature data via SNMP? The existing templates for APC devices in devmon don't have any 'temp' test, but if the data is there that can be fixed.

If your platform supports it you can use ipmitool for various internals. Actual server room temp would need some external device such as the ones others have mentioned.
Example:
On a Sun X4150 box one of the sensors is Ambient Temp0.
temp="/usr/sfw/bin/ipmitool sensor reading 'Ambient Temp0' | awk '{print $NF}'"
Other hardware has different sensor names, some just have (temp) sensors for CPU die temps.

I'm using OneWire DS18S20 sensors from Maxim-IC.com to watch room and refrigerator temps in my wife's dairy at home. Right now it's a bit of a hack, with the sensors just soldered onto old phone cables, but it works just fine. The fridge seems to be maintaining about 25F while the room temp gets up over 85F.
I'm using digitemp to read the sensors, which can be hooked up to either USB or serial ports, though it's also possible to use owfs. The readings are fed to Hobbit via a custom script that generates NCV compatible data for graphing.
The bare sensors are about $5, and the USB or serial port connector is around $30. You can use any old ethernet or phone cable.

I am using a Netbotz 320 device in my network and DC's. I have linked them to Hobbit using MRTG and bbmrtg.pl for temp and humidity and alerting. Here is an example MRTG entry for a 320 Netbotz:
