Monitoring CPU temperature for small IOC

[David Morris <David.Morris@triumf.ca>]

Hello all
  I have a Linux based IOC running on a dedicated small hardware 
platform (Atom CPU in Mini-ITX form factor) We would like this to have 
no moving parts, which means monitoring the CPU state becomes critical 
on hot summer days. Is there support for monitoring CPU temperatures 
using the /proc/acpi service? It seems like this would be something that 
devIocStats could provide, but perhaps it is too system dependent.

  Is there an easy way to collect information from the IOC host system 
and place it into PVs? Regular reading of /proc/acpi/thermal_zone/THRM 
will give an updated CPU core temperature, but it is not clear to me how 
to place this into a PV.

  Thanks in advance.

David
