Monitoring server

You can create a monitoring server using metrics.server(). Net.Server instance is returned.

var server = metrics.server();

server
    .listen(8000)
    .on('error', function(e) {
        // handle errors
    });

This is a raw socket server. Then connected, it began to dump screens of text until connection is closed:

# nc monitoring.host.tld 8000
