title: NLog global properties
body: <p>Using NLog is there any way to define global <code>LogEventInfo</code> properties for logs?
  Using construction </p>
  
  <pre><code>var logEventInfo = new LogEventInfo(LogLevel.Trace, Log.Name, "Hello world");
  logEventInfo.Properties["messageName"] = "MessageName2";
  </code></pre>
  
  <p>isn't suitable, because in big project everywhere using <code>Info(...)</code> and similar methods. But we need to add some parameters to watch them at <code>Gelf</code> logging without rewriting code.</p>
