I did exactly this, but there was no additional graph anywhere... Did I 
understand you correctly that this new graph would only show up under 
"trends"? After writing several custom checks and defining custom graphs 
for them, I am somewhat familiar with the whole thing, but I thought it 
was possible to add (or replace the) to the default "conn" graph under 
my main host. :-/

I am using Debian as well, so this was very helpful. :-)
