Retrieves sensors output and formats it for inclusion in the MythTV backend status page
TODO:
- This script only works when sensors is run with a specific locale. One workaround may be to specify
export LANG=en_US.US-ASCIIat the top of the script. Better would be to write a better script.

# Retrieves sensors output and formats it for inclusion in the MythTV backend
# status page.
# The following line outputs information to include the CPU temperature
# information in the backend status page. Though the sensors output includes
# the °C unit marker, it is stripped out of the data before being placed in the
# output page, so the display value includes a proper HTML entity.
#sensors | awk '/CPU Temp/ { printf "Current CPU Temperature: %s ℃.[]:[]temperature-CPU[]:[]%s\n", $3, $3 };'
# The following lines output CPU and Motherboard temperature and CPU and Case
# fan speed information. Modify the patterns (i.e. /CPU Temp/) to match the
# sensors output lines containing the data you want to grab (i.e. /Core0
# Temp/). Continue adding lines to the awk program as desired to include
# additional information.
sensors | awk '
/CPU Temp/ {
printf "Current CPU Temperature: %s ℃.[]:[]temperature-CPU[]:[]%s\n", \
$3, $3

/M\/B Temp/ {

"Current Motherboard Temperature: %s ℃.[]:[]temperature-MB[]:[]%s\n", \

/CPU Fan/ {

# With appropriate authentication in place (i.e. using SSH Certificate
# Authentication), you may also retrieve sensors data from remote system (i.e.
# slave backends, remote frontends, etc.). Do so with commands of the format
# below (provide an appropriate hostname in place of "slave" (3 places) and
# replace the awk script with one providing the desired information as shown
# above):
#ssh -q slave sensors | awk '/CPU Temp/ { printf "Current CPU Temperature (slave): %s ℃.[]:[]temperature-CPU-slave[]:[]%s\n", $3, $3 };'
# Alternatively, this information could be retrieved from an appropriate
# monitoring program (monit, mrtg) or by using SNMP, depending on the system
# and network configuration.
