nlog.targets.lumberjack

A custom target for NLog that allows sending logs over the Lumberjack protocol to for example Logstash.

Install

nuget install nlog.targets.lumberjack

Configuration

Configure Logstash as a target in your NLog.config file,

<?xml version="1.0" encoding="utf-8" ?>
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <extensions>
    <add assembly="NLog.Targets.Lumberjack" />
  </extensions>
  <targets>
    <target name="logstash" type="Lumberjack" host="127.0.01" port="5001" layout="${message}"/>
  </targets>
  <rules>
    <logger name="*" minLevel="Trace" appendTo="logstash"/>
  </rules>
</nlog>

Options

• host: The IP address or host name where logs should be sent. (Required)
• port: Port number on host to connect to (default: 5000)
• fingerprint: If set, this will be used to verify the certificate hash of the remote server.
• encoding: Text encoding to be used for properties.

This target supports the standard NLog layout directive to modify the log message body.

Caveats

At this moment no attempt is made to implement the windowing and ACK parts of the Lumberjack protocol.
