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
