error creating rrd DS (invalid DS name)

[Tracy Di Marco White]

I guess I missed something trying to add data collection for a test
I created.

The test sends data like so:
--------
afs-6,iastate,edu.afs green Wed Sep 7 16:42:25 CDT 2005
Instance fs, currently running normally.
     Auxiliary status is: file server running. &green
calls waiting: 0 &green
--------

I added ",afs=ncv" to the end of TEST2RRD and
NCV_afs="Auxiliarystatusis=NONE,callswaiting=GAUGE"
in hobbitserver.cfg 

I get this in rrd-status.log:
2005-09-07 15:41:21 RRD error creating /usr/pkg/hobbit/data/rrd/afs-6.iastate.edu/afs.rrd: Invalid DS name

As hobbit, I can touch this file to create it.  Any ideas?  Where are
the constraints on DS names listed?
