NLog.Targets.Splunk.Simple

NLog.Targets.Splunk.Simple is a Splunk HTTP Event Collector target for NLog. Unlike the original, this fork does not batch or retry the HTTP requests on it's own, but rather delegates that to NLog, so the standard wrappers can be used.

Getting started

First you will need to have a running install of Splunk Enterprise and setup a HTTP Event Collector

Then configure the SplunkHttpEventCollector with ServerUrl and Token:

<?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.Splunk.Simple" />
  </extensions>
  <targets async="true">
    <target name="Splunk"
            xsi:type="SplunkHttpEventCollector"
            serverUrl="https://splunk-server:8088"
            token="token-guid"
            channel="channel-guid"
            source="${logger}"
            sourceType="_json"
            index=""
            includeEventProperties="true"
            includePositionalParameters="false"
            includeMdlc="false"
            maxConnectionsPerServer="10"
            ignoreSslErrors="false"
            useProxy="true"
            proxyUrl="http://proxy:8888"
            proxyUser="username"
            proxyPassword="secret"            
            >
		<contextproperty name="host" layout="${machinename}" />
		<contextproperty name="threadid" layout="${threadid}" />
		<contextproperty name="logger" layout="${logger}" />
	</target>    
  </targets>
  <rules>
    <logger name="*" minlevel="Debug" writeTo="Splunk" />
  </rules>
</nlog>
