Read the error message again!
You run rrdupdate /var/lib/rrd/outside.rrd N:'snmpget -c ...
This is not what you want! You have to fix your quoting.
You want something like rrdupdate /var/lib/rrd/outside.rrd N:`snmpget -c ...
(Notice the backtic ` instead the single quote ' !)
Anyway I recommend storing the output inside a shell variable like:
in1=`snmpget -c public -v 1 -Oqv 192.168.1.1 ifInOctets.1`
and use this in your rrdtool call:
rrdtool update ... "N:${in1} ...
This would result in a more readable code ;)
HTH,
Andreas.
