I know this has been mentioned before, but other than NetBotz (too pricey), what are people use as ethernet-based, SNMP-probable temp sensors? I very simply need to trend temp with cricket/mrtg in various parts of the data center. Looking for real-world experience.

We use a Temptrax device (around $250) which we wrote our own interface for graphing and alerting. No SNMP, but the price is right. They also provide plugins for several monitoring systems. Bob

Turning the question around, what sort of price point are you looking at? A guesstimate says that there's $150 worth of *parts* in a box just to do temperature monitoring that will take an EtherNet connection (unless you were manufacturing a gazillion of them).

I suppose if one had enough time and interest, and some Java skills, you could make something out of these: http://www.ibutton.com/ibuttons/thermochron.html http://www.ibutton.com/TINI/applications/sertoeth/ Oops, somebody's already done it: http://www.maxim-ic.com/appnotes.cfm/appnote_number/1048/ln/en Looks like the total hardware cost would be around $100 for the TINI and board, and $8 for each sensor (iButton and holder). I have little time and no Java skills, otherwise it looks like a cool project. If somebody wants to develop a machine room temperature monitoring network out of them, I'd be a beta tester ;) Bill.
The environmental monitors which APC sells work well and they can be configured via BOOTP. They are in the $200 range. They also sell units which install into the smart slot on APC ups units which gives you remote control of the UPS as well as the environmental monitoring. Scott C.

APC Makes a nice little monitor unit (AP9312TH), List price is $279.00, but you should be able to get them cheaper off the web. If you have APC UPS's on-Site, they also have environmental modules that plug directly into the SmartSlot.
