[rrd-users] problem with more than one dot in file name?

[Carsten Aulbert]

Hi,

I've tried to find something in the archives about this, but so far have found 
nothing. We are recording user usage of our cluster and safe the RRDs with 
their login names in the file names. A user which has a dot there, seem to 
cause problems:

rrdtool graph  /tmp/run_hour.png  --lower-limit=0 --upper-limit=7000 --rigid 
--end now --start end-103600 --width=1024 --height=768 --slope-mode --
vertical-label="# of jobs" --title="jobs hour: atlas1:606 atlas2:1625 
atlas3:4593"  DEF:ds_user1_run=/path/to/user1_run.rrd:slots:AVERAGE 
DEF:ds_user.num2_run=/path/to/user.num2.rrd:slots:AVERAGE 

When we leave out the second user, all is fine, but adding the user we get an 
error:

ERROR: Cannot parse vname from 
'DEF:ds_user.num2_run=/tmp/user.num2.rrd:slots:AVERAGE'

Is this a bug or a feature or me being stupid ;)

Cheers

Carsten
