No graph of nmailq-bf.sh

Hi,

 
I am not getting the graph of the nmailq-bf from my client, however I am
able to get other graphs from the same machine such as 

Vmstat, netstat... 

 
I have noticed that there is no mention of nmailq in the hobbitgraph.cfg
file, instead there is codes for mailq not nmailq. Secondly I tried
changing nmail to mailq but still it didn't come...I tried changing
"LARRDS" field of hobbitserver.cfg from nmailq to mailq..but still no
graphs

 
Any idea where I should be looking at...

Regards

Soumya
