how to see open connections in mongodb

Question

The last log I see in the mongod process is :

[conn5] end connection 127.0.0.1:62206 (4 connections now open)      

When I call mongo stat, I get:

insert query update delete getmore command flushes mapped  vsize   res faults qr|qw ar|aw netIn netOut conn     time

.... (omitted)

As far as I understand, I have just one connection according to mongostat.

EDIT: I looked into the db.serverStatus().connection, it s cool and all but not much detail either..

/* 0 */
{
    "current" : 5,
    "available" : 999995,
    "totalCreated" : NumberLong(11)
}

How can I get more info about this connection? Thanks
