Get A Free Local Log Viewer
The Loupe Viewer allows you to quickly add logging to your .NET and Java applications with an easy-to-use API. It offers simple methods for nearly any logging scenario, and options to gather more sophisticated application metrics. If you have already invested in another logging API that's no problem – it is simple to forward data into Loupe to take advantage of everything the Loupe Viewer offers.Get the Loupe Viewer
Our focus on .NET and Java means we've implemented a range of agent extensions for technologies you're using in your application – like Spring and Hibernate for Java or Entity Framework, ASP.NET MVC in .NET. We even have specialized support for desktop environments like WPF and WinForms.
Add in our open source extensions (also available on NuGet) and you get smart logging and performance analysis without any effort.
Watch Your App While it Runs
Watch the log messages emitted by your application in real time while it's running. This will open up new debugging possibilities by walking through trace data without having to break your application's execution.
If you have multiple processes that all have to work together, it's even more helpful to peer into each one without having to hook up the debugger and slow down the application.
Log messages are integrated with metric graphs so that you can relate the point in time for any message with the metric values at that time.
Loupe also provides powerful charting so you can, for example, create Pareto charts that identify performance problems.
Solve Problems by Seeing What Led up to Them
When developing you're going to have some unexpected behavior. Exceptions and bad results are par for the course when you're writing code. Between your logging and Loupe's agents you can see what happened leading up to each error to be sure you're fixing the real problems. Plus, you'll gain confidence that you can solve similar problems that may happen after you've deployed based on your log data.
The Loupe Client provides a powerful log viewer and more. It's free, easy to install (or deploy with your application), and a lot better than pawing through your data with a text editor or Excel. Loupe makes it easy to highlight or filter messages by class, method, category or severity and shows the associated source code when a log message is selected in the Loupe Desktop viewer.
