How to determine active socket connection count?

[Frederic Bregier]

Hi Neil,

What Trustin was saying could be written as you need to do something like
this in your handler (from SimpleChannelHandler for instance):

static DefaultChannelGroup allChannels  = new
DefaultChannelGroup("netty-receiver");

	void channelConnected(ChannelHandlerContext ctx, ChannelStateEvent e) {
                  allChannels.add(e.getChannel);
        }

Such that each time a channel is newly connected, it includes itself in the
group allChannels.
Then in allChannels, you will have the current number of connections (+1 if
you add the parent channel as you show in your example below).
You don't have to remove them from the group since they will remove
themselves when they are closing.

Also, using such a group is useful when you want to shutdown the service
(see the manual of Netty for that).

HTH,
Frederic
