A search at http://www.merit.edu/mail.archives/nanog/ on "temperature" reveals this thread in the top 10 hits: http://www.merit.edu/mail.archives/nanog/1997-06/msg00302.html Looks like a few people mentioned some vendors that sell these devices. cheers, -- Scott Francis || darkuncle (at) darkuncle (dot) net illum oportet crescere me autem minui

From Google: http://www.syrona.co.uk/sensorprobe_description.htm http://www.dcf.sk/microweb/snmpmain.html http://www.omnitronix.com/solutions/envmon.htm or if your Cisco router is capable...

They're hard to find, at least inexpensively. I've found several systems for >$700 that have some nice features, including cameras (http://www.rackbotz.com/) and multiple wireless measurement systems (http://www.microstrain.com/WWSN.html) but they've all been slightly out of range in the cost department, or have been aimed at a different market than what I was looking for. Using the Cisco temperature MIB has been pretty much the standard to this point. After some extensive hunting a while ago, I found this: These guys make a nice (fairly) inexpensive module that I think wins the competition. It has a large number of measurement and switch inputs, runs a number of relays (built in) and seems to be fairly customizable. The bad news: it's not "native" SNMP and requires some sort of little C or Perl module to do screen-scraping. The vendor provides a sample MRTG script, so it can't be that hard. http://rms.nethop.net/ $395 plus a lot of features, including running on minimal voltage. I haven't purchased one of these yet, but they're close to what I've needed several times in the past, and I'm looking for excuses to purchase a few. Any of you who pick one up, I'd appreciate it if you could send feedback to me personally. It seems to me that there still is not any widely-advertised, inexpensive temperature gauge that is network-accessible (SNMP) which is surprising considering the amount of damage that can be done via overheating in a datacenter. [Note: before I sent this, I read Robert Boyle's followup message, which has some interestingly low-priced alternatives. Perhaps I have been looking in the wrong places. In any case, the RMS device has some additional features that may make it worth examining for the remote or low-voltage wireless sites that are starting to appear with some frequency here in in the Pacific Northwest American area.] JT

The easier answer is "define cheap". So this is my 2 cents, I'm about to try this product (in a few weeks) across some POPs. AKCP Sensorprobe2: http://www.akcpinc.com/company/sensorprobe.html Thomas

FWIW, these appear to be the same product, re-labeled by two different companies... unless it's just a coincidence that these devices have the same back panel with three RJ-45 plus DC-in and blue curved housing? http://www.akcpinc.com/company/sensorprobe.html http://www.uptimedevices.com/sh2plus.html http://www.uptimedevices.com/productpdfs/sh2plus.pdf My guess is that it's made somewhere in Taiwan or mainland china and might be available at a much lower cost. :) Eric Kuhnke At 01:32 PM 4/23/2003 +0200, you wrote:

This is a bit of a late reply, but it appears that there is a reasonably inexpensive solution that I had not found when I originally replied to this message: http://www.sensatronics.com/TempTrax/index.html There are serial versions and ethernet-based versions. The serial version looks simple enough even to connect to the console of a Cisco for remote access via a script, and the ethernet version doesn't appear too complex, either. (Does a standard Cisco AUX port provide DTR power?) The downside is that they're not SNMP-capable directly; an intermediate glue routine would need to be written. You can find Nagios (a popular Open-Source monitoring platform) plug-ins for these devices here: http://www.nagios.org/products/ JT
