This is a nice simple script to display CPU core and disk temperatures on a FreeNAS server. Tested with FreeNAS 9.10.2-U1
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/')) print $i }' ) ; 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
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
HDD Temperature:
