configuration question

[ppokorny@penguincomputing.com (Philip Pokorny)]

Another way to attack this would be to create some "standard" labels 
that your SNMP module would look for.

Then a user of your script would need to make sure the sensors.conf uses 
the "LABEL" directive to name the appropriate values correctly.  In that 
way, your script is independant of the chipset in use.

You could then create entries for -5V, 5V, 3.3V, 12V and -12V (which are 
the standard power supply voltages and generally available). 
5V-standby, 3.3V-standby and Vbat (battery voltage) are also frequently 
available.

Then create a table? for Fan speeds and number them fan1, fan2, fan3. 
Some motherboards have multiple monitoring chips and can monitor as many 
as 6 or more fans.

Basically, pick a common subset of readings and then name them in a 
standard way.  We may be doing something along these lines for the next 
release of the libsensors library...
