prometheus-net.DotNetRuntime/src/prometheus-net.DotNetRuntime/EventListening/Parsers/SocketsEventParser.cs

Lines 16 to 20 in 747138a

	[CounterName("bytes-received")]
	public event Action<MeanCounterValue> BytesSent;
	[CounterName("bytes-sent")]
	public event Action<MeanCounterValue> BytesReceived;

That's not right!
