Gelf4NLog

Gelf4NLog is an NLog target implementation to push log messages to GrayLog2. It implements the Gelf specification and communicates with GrayLog server via UDP.

Solution

Solution is comprised of 3 projects: Target is the actual NLog target implementation, UnitTest contains the unit tests for the NLog target, and ConsoleRunner is a simple console project created in order to demonstrate the library usage.

Usage

Use Nuget:

PM> Install-Package Gelf4NLog.Target

Configuration

Here is a sample nlog configuration snippet:

<configSections>
  <section name="nlog" type="NLog.Config.ConfigSectionHandler, NLog" />
</configSections>

<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

	<extensions>
	  <add assembly="Gelf4NLog.Target"/>
	</extensions>

	<targets>
	  <!-- Other targets (e.g. console) -->
    
	  <target name="graylog" 
			  xsi:type="graylog" 
			  hostip="192.168.1.7" 
			  hostport="12201" 
			  facility="console-runner"
	  />
	</targets>

	<rules>
	  <logger name="*" minlevel="Debug" writeTo="graylog" />
	</rules>

</nlog>

Options are the following:

• name: arbitrary name given to the target
• type: set this to "graylog"
• hostip: IP address of the GrayLog2 server
• hostport: Port number that GrayLog2 server is listening on
• facility: The graylog2 facility to send log messages

###Code

//excerpt from ConsoleRunner
var eventInfo = new LogEventInfo
    			{
					Message = comic.Title,
					Level = LogLevel.Info,
				};
eventInfo.Properties.Add("Publisher", comic.Publisher);
eventInfo.Properties.Add("ReleaseDate", comic.ReleaseDate);
Logger.Log(eventInfo);
