change test name 'conn' to link

In my bb installation i have renamed the conn test as 'link'.

I would like to change it also in my hobbit installation so i have change:

in hobbitlaunch.cfg

CMD bbtest-net --report --checkresponse --ping=link

in hobbitserver.cfg

link=tcp

Now the column link is generated but no larrd graph.

any ideas ?

thanks
