Logs produced by NLog can be analyzed using a number of GUI tools:

• Gibraltar (using Gibraltar Adapter for NLog) - https://nlog-project.org/2009/11/01/gibraltar-adapter-for-nlog-released.html
• Sentinel - https://github.com/yarseyah/sentinel
• NLogViewer - http:https://github.com/jkowalski/NLogViewer (functional, but no longer in development, not recommended)
• LogEntries - http:https://www.logentries.com (service for cloud logging, has .net NLog target)
• Legit Log Viewer - http:https://www.legitlog.com/ (Although their website is down, it is Free and powerful log viewer.)
• ReflectInsight Viewer (using the ReflectInsight Extension for NLog) - http:https://insightextensions.codeplex.com/

In general, any viewer supporting Log4J or Log4Net should work fine with NLog - see Chainsaw Target for information on configuring NLog for use with those viewers.
