NLog DiagnosticListener for DiagnosticSource

Question

是否有任何 NLog 包提供与日志 .NET 诊断源模型的本机集成？有点像NLogTraceListener...

乍一看，在谷歌上看不到任何东西。

也许你可以执行DiagnosticListener.AllListeners.Subscribe，然后转发到NLog-Logger：

DiagnosticListener.AllListeners.Subscribe(delegate(DiagnosticListener listener)
{
// subscribe to the Service Bus DiagnosticSource
if (listener.Name == "Microsoft.Azure.ServiceBus")
{
// receive event from Service Bus DiagnosticSource
listener.Subscribe(delegate(KeyValuePair<string, object> @event)
{
// Log operation details once it's done
if (!@event.Key.EndsWith("Stop"))
return;
var currentActivity = Activity.Current;
NLogLogger.Debug($"{currentActivity.OperationName} Duration: {currentActivity.Duration}nt{string.Join("nt", currentActivity.Tags)}");
});
}
});
