I've used a couple of these for many years. http://www.temperaturealert.com/Wireless-Temperature-Store/Temperature-Alert-USB-Sensor.aspx
Can use stand-alone, as I do, or with a cloud subscription for remote management, reporting, monitoring (no experience with that). Stand alone has email alerts, SNMP, can shutdown the server, log to XML or win event log, use powershell scripts on it, etc. I use only the email alert and various logging capabilities. Works great and has not hung/failed, ever, in 6+ years. Website lists up to Server 2008 compatibility, but I've been running it on Server 2012 R2 (64-bit) for some time without issue, and Server 2003 (32-bit) prior to that. There have been comments about a stand-alone monitor not being dependant on the server. Yes, if the server the USB is plugged into goes down the temp monitor will not work either. But that trips its own alerts and requires intervention anyway. Besides, stand-alone (or UPS based) devices are not somehow immune to failure. Only two different devices (powered on different circuits, delivering alerts by different channels, etc) start to address the redundancy issue. I'm not uncompensated by my employer, but am not, not uncompensated by the maker of the temperature@alert. -- Mark From: "Dave Lum" <[email protected]> To: <[email protected]> Date: 06/18/2015 10:40 AM Subject: [NTSysADM] Recommended product - server room temperature monitor: monnit.com Sent by: [email protected] I figured I?d throw out a recommendation for a server room temperature monitoring tool I?ve used for several months now. I had a client buy a USB temperature monitoring kit + 1 additional USB gateway, and for about $250 (includes 1 year of their $39/yr. premier subscription) total I am able to monitor two separate server rooms in two different buildings and get alerts. The alerting comes from their servers and you can check the status via web portal or even a mobile app. I have used their tech support a couple of times and it?s U.S. based and excellent. http://www.monnit.com/ I am not uncompensated for this pitch and I am unaffiliated with them, but I did stay at a Holiday Inn Express once.
