In my pix/fwsm template (I posted them), I am using 'conns' name, with Devmon 
RRD (requiring an extra-script such as my extra-rrd.pl) to graph the number 
of connections.

Since I don't think it is currently feasible to get all graphs we want into 
Hobbit with existing hobbit support, I think it would be best (for now) to 
ship a devmon extra script (one which uses the RRD information created by the 
rrd option). In future, we can integrate the support for this into Hobbit, or 
switch to the new trends feature in 4.3.

I don't think we should abuse the ports test name for this, because the data 
is different (just the number of connections, no detail etc.).

If you want to alert on the same data, I don't think sending a 'data' message 
will work. So, 'status' is the only option for now.

I'd rather ship a release that has graphs that work as soon as possible (even 
if that requires running one extra script in hobbit) than delay shipping a 
solution because we want a perfect one. Im-perfect graphs are better than 
none.
