We now need to configure the lm-sensors application. So, from a Terminal/Putty Session issue the following two commands:

To make this script work we need to install lm-sensors. The scripts do give you a few tips but obviously I’m unable to test the scripts on every motherboard/hard drive out there! How to shut down the server if the CPU gets too hot You’ll need to tweak the instructions to work in your environment. Furthermore the output from the utilities we’re going to install varies across different motherboards/processors and hard drives. NOTE: These instructions have been tested on Ubuntu Server Lucid 10.04, Karmic 9.10, Jaunty 9.04 and Intrepid 8.10. To keep things simple we’re going to be using two scripts: One script will monitor CPU temperatures and the other script will monitor hard drive temperatures. If either of the CPU cores or any one of the hard drives exceeds my pre-determined temperatures then the scripts will send me an email and will then shut the server down. The CPUs and hard drives are useful things to monitor so this is what these scripts will do. So, I decided to write some scripts which would monitor the server temperatures for me. Whilst computers do have an inbuilt safety mechanism, and will automatically shut down if things get too hot, this mechanism doesn’t kick in until things get VERY hot, much hotter than I’d feel comfortable letting my server get to. The vents are installed in the top of the cupboard and could easily get covered over with a book or something. Monitor critical temperatures in Ubuntu Server – Trusty, Lucid & KarmicĪs my server is going to be living in a cupboard I was concerned what would happen if one of the cupboard vents got blocked somehow.
