A couple of things to check:
In the hobbitlaunch.cfg ensure that in the --extra-tests for the "rrdata" section has "mpstat" listed, also the--extra-script points to the rrd_data.pl script. It probably does since you are creating the rrd data files....
In the hobbitserver.cfg, ensure that under the TEST2RRD "mpstat" is listed., also under the "GRAPHS" section.
Then under the hobbitgraph.cfg file:

Thanks for the input, but all you mentioned is implemented.
It looks like the rrd_data.pl isn't sending the data to the rrd files. How can I check that ? When I run the rrd_data.pl script manually with the hobbit_mpstat.hostname.send as input file using the command
server/ext/rrd_data.pl sodn034u mpstat client/tmp/hobbit_mpstat.sodn035u.send I get the following output:

Bert,
If "rrd_data.pl" is an external processor, it does not send data to RRD directly -- it simply emits the commands needed for the Hobbit process to update the RRD. Based on what you posted, I think you are on the right track -- the rrd_data.pl script is not parsing the test data in order to get data for multiple CPU's, so it is not issuing the proper commands to update multiple RRD's. I suspect that the person who wrote this section of the script probably assumed there would only be one CPU reported, or only the aggregate needed to be graphed. Not a bad assumption, but it is not working for you.
Since "rrd_data.pl" is a custom script, you will have to go back to the person who wrote the script to get them to update it for you, or you will need to update it yourself. What you will need to do (in the section that parses this test) is update the code to track multiple CPU's and then have it loop through them to generate the RRD commands for each CPU so the right RRD's are created/updated. Then you need to double check your Hobbit graph definition to make sure that it can handle multiple CPU's as well.
Good luck!

Hi Greg, the mentioned custom script ( rrd_data.pl ) seems to be a part of the initial release of mpstat dated 2006-11-26 . Therefore Your answer confuses me.

Anna, sorry my answer was confusing. I would change my answer to "you need to contact the people who maintain mpstat for assistance".
In my own environment, I have a generic script that handles the graphing needs for all of my custom scripts, so my suggestion was based on what I know to be true about generic graphing under Hobbit.

Everything should be there to get that mpstat data graphed.
