.Net C# Logging NLog

Custom Layout Renderer for NLog using C# New

In a previous blog post – Custom Layout Renderer for NLog using C#, I have mentioned about how to create a class inheriting LayoutRenderer and writing custom Layout Renderer.

This blog post talks about inheriting from WrapperLayoutRendererBase class.

The WrapperLayoutRendererBase class has a method with the signature:

protected override string Transform(string text)

This method needs to be overridden. The nice thing about using this class is other layout renderers can be used in combination.

Here is a GitHub repo implementing hash functions that can be used as LayoutRenderers.


The source code has 4 projects:

  1. The actual implementation
  2. Unit Tests
  3. Benchmark Tests
  4. Example

The usage is straightforward, use hash or securehash layout renderer.

    <add assembly="ALight.NLog.LayoutRenderer.Hash" />

<target xsi:type="File" name="logfile" fileName="c:\temp\console-example.log"
        layout="${longdate}|${level}|${message} |${all-event-properties} ${exception:format=tostring} ${hash:hello} 
        ${securehash:value=${level}} ${event-properties:item=secret} ${hash:${event-properties:item=secret}} ${hash:${level}}" />

The hash implementation is about 10 – 11 times faster but uses Murmur3 non cryptographic hash.

I might consider a nuget package at a later point, but not now, because the code is very minimal and like a small helper class.

I don’t have any fake aliases, nor any virtual aliases like some of the the psycho spy R&AW traitors of India. NOT associated – “ass”, eass, female “es”, “eka”, “ok”, “okay”, “is”, “erra”, yerra, karan, kamalakar, diwakar, kareem, karan, sowmya, zinnabathuni, bojja srinivas (was a friend and batchmate 1998 – 2002), mukesh golla (was a friend and classmate 1998 – 2002), thota veera, uttam’s, bandhavi’s, bhattaru’s, thota’s, bojja’s, bhattaru’s or Arumilli srinivas or Arumilli uttam (may be they are part of a different Arumilli family – not my family).
