FreeNAS CPU core and disk temperature check script

This is a nice simple script to display CPU core and disk temperatures on a FreeNAS server. Tested with FreeNAS 9.10.2-U1

1. Create a file with the following content - Mine is just called temps_check_script.sh as an example:

   # Write some general information
   echo System Temperatures - `date`
   uptime | awk '{ print "\nSystem Load:",10,11,12,"\n" }'
   
   # Write CPU temperatures
   echo "CPU Temperature:"
   sysctl -a | egrep -E "cpu\.[0-9]+\.temp"
   
   # Write HDD temperatures and status
   echo "HDD Temperature:"
   for i in(sysctl -n kern.disks | awk '{for (i=NF; i!=0 ; i--) if(match(i, '/da/')) printi }' ) ; do
   echo i: `smartctl -a -n standby /dev/i | awk '/Temperature_Celsius/{DevTemp=10;} /Serial Number:/{DevSerNum=3}; /Device Model:/{DevVendor=3; DevName=4} END {printf "%s C - %s %s
   (%s)", DevTemp,DevVendor,DevName,DevSerNum }'`;
   done
   

2. Ensure that the script is executable:

   chmod +x temps_check_script.sh
   

3. Run it with ./temps_check_script.sh - The output looks like this:

   System Temperatures - Wed Jun 21 07:53:16 AEST 2017
   
   System Load: 0.17
   
   CPU Temperature:
   dev.cpu.3.temperature: 40.0C
   dev.cpu.2.temperature: 44.0C
   dev.cpu.1.temperature: 40.0C
   dev.cpu.0.temperature: 42.0C
