Weird. running the test by hand gets me this
hobbit at randomaccess ~/server/ext $ ./cputemp.sh currant.tbb cputemp
currant.tbb.cputemp.out
DS:cputemp:GAUGE:600:0:U
cputemp.rrd
100

but cputemp.log in /var/log/hobbit shows only

DS:cputemp:GAUGE:600:0:U
cputemp.rrd

DS:cputemp:GAUGE:600:0:U
cputemp.rrd

DS:cputemp:GAUGE:600:0:U
cputemp.rrd


No temp!
rrdtool dump on cputemp.rrd shows me a buncha
