[hobbit] RRD data not being created.

[Hubbard, Greg L]

I am not exactly sure what you are doing, Rob.

It looks like your log file is getting what should be going to STDOUT
when the script runs.  That won't help.

Can you post the content of cputemp.sh?

BTW, are you planning to ever run more than one custom test?  If so,
naming the "catcher" script that way will cause some interesting
maintenance issues down the road.  Or are you doing this simply to get
it working...

GLH

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
