Is there a way to know how many volatile messages are dropped with Socket.IO on Node.js?

I searched a bit around and didn't find nothing about this particular issue. I am currently developing something that involves Socket.IO on Node.js.

My question is pretty simple : is there a way to know how many messages are dropped from a socket.volatile.emit() ?

Thanks for any tips!

No counter incremented, but you could turn on logging to take a look.
