Cluster Temperature Monitor

1. Extract CPU temperatures

   $ sensors | grep '^temp[0-9]:' | sed -e 's/.*: \+[+-]\([0-9.]\+\)°C.*$/\1/'
   27.8
   29.8
   

2. If one of the CPU cores on a node computing node reach +70 °C, write the node name and the temperature to file data/$temperaFile

   $ cat data/2019-05-12_13\:00\:01 
   71.0 node06
   71.0 node06
   

3. If data/$temperaFile is not empty, notify the lab members by sending an email to given address with the content from file data/$temperaFile

   php temperatureWarning.php data/$temperaFile
   

4. This program will check the temperature every hour. We use cronjob to make the program run every hour
