kit.s3Speed(topic,userId,sessionId,videoType,videoTimestamp,videoId,speed,size,time);

Events Emitted

socket.on('message',function(topic,res){})

description: generic listener for anything not expecting a res from .register method.

Example:

socket.on('message',function(topic,res) {
	console.log(topic,res	
}

socket.on('connect',function(){})

description: called when connected. If you need to do something after connected put inside this event. Is called again on reconnect so do NOT nest other listeners inside

Example:

socket.on('connect',function(){
	console.log('now connected');
};

description:If reconnect happens.

Example:

socket.on('reconnect',function(){
	console.log('now reconnected');
};

description: happens if error happens during connect or publish.

Example:

socket.on('error',function(error){
	console.log(error);
};

description: happens if state is switched to offline from online.

Example:

socket.on('disconnected',function(){
	console.log('now disconnected');
};

description: happens if reconnect fails(still offline).

Example:

socket.on('reconnectFailed',function(){
	console.log('now offline');
};

description: happens if socket connection is closed.

Example:

socket.on('close',function(){
	console.log('now closed socket');
};

###Disconnect Logic:

From there their client will try to reconnect every second(all socket events will be thrown into a queue).

Once reconnected will send reconnect message over all sessions they can publish to, empty their socket queue and emit a connect call from their socket.

socket.on('client.connected',function(obj){})

description: Happens if a new client connects to your topic

return: OBJECT {topic:topic,client:client_id}

Example:

socket.on('client.connected',function(res){
	console.log(res.topic,res.client);
};
