[Cialug] SNMP & lmsensors, oh my!

I'm using the value for doing graphing with Cacti... Is there any way to
edit the MIB object, or is it just worth it to go compile SNMPd with
lmsensors support?

This value is defined in the MIB object.  You could always rewrite the MIB,
but if you are using the value in a shell script, why not just force your
variable to a typeset of integer?

I'm looking to integrate sensors monitoring into SNMP without having to 
recompile SNMPd. I figure that using an external script might work, but the
results come back as NaN rather than a number. When I do an snmpget, it
shows the data type as string. Is there any way to force this to integer or 

root at dilithium:~ # snmpget -v 1 -c public localhost
UCD-SNMP-MIB::extOutput.1 = STRING: 71.0

root at dilithium:~ # cat cputemp.sh 
#! /bin/sh
sensors | awk '/CPU/ {print substr($3,2,length($2)-1)}'
