Hello,


So, I wrote a Hobbit(xymon) Script that gives the number of users
accessing specific URL's which goes into the RRD database.

I now want to track the number of users accessing another
URL, so I modified my hobbit script and the hobbitgraph.cfg.

However, I can't see the new data. What's the easiest way to
get the new value into the RRD database?

I know I can just remove the existing database and have it
re-create the database and it will start pulling the new data.

However, I want my old data from the other values in there
in addition to the new one.

Any assistance would be appreciated.
Don't blame me it it screws up your rrd, but I attached the script that I
use. It searches a predefined directory (/home/users/hobbit/data/rrd/) for
the files vmstat.rrd to add a DS.  I used this to add 2 extra counters from
Power5 CPU virtualisation.
I changed my script so you can give the needed information as paramaters on 
the command line.  You can download it from:
