Temperature checks

Created by: gladky

From the DAQDottoressa temperature monitor: tail -3 /var/log/danger_shutdown.sh.log | grep -i Temperature

1. Is it the preferred way of obtaining temperature? Is it there any api?
2. Are the thresholds up-to-date? 21 - normal, 25 - warning, 27 - warning 2, 30 - shutdown (based on code and messages from DAQDottoressa
3. What temperature is it exactly? What exactly is "everything" that shuts down above 30 degrees (quote 2)?
4. Is shutting down the action of DAQDottoressa? ("...At 30 degree I shut down..." from quote 1)

Quote 1:

===> BIIIG TROUBLE AHEAD <===. It's getting hot here. Temperature is now $temp. At 30 degree I shut down...and I take the entire computer cluster with me:-(\n(For your info: a normal temperature is 21 degree.)

Quote 2:

===> This is the end, my friend... The computer cluster is being cooked ($temp degree). \nVery soon everything shuts down. Lean back and relax... there is nothing you can do... sad sad world...\nIt is up to you to decide if you want to inform your control room friends now, or if you leave them some more happy minutes \nuntil they realize. Once the cluster really goes down please call the DAQ expert (76600) also during night time.\n(...I hope that at least your phone is heat resistant...)\n
