This one might help:

kern.ipc.numopensockets: Number of open sockets

It's usefulness will depend on the granularity you require (in only, out
only, established only, etc) but it's always represented system-wide
resource consumption very well (matching observed workloads - <some
baseline value>)

Thank you, it is very helpfull, using kern.ipc.numopensockets with 
sockstat(1) and netstat(1) will give me a clue to tune kern.ipc.somaxconn

Thank you all.
