Track every error in your software
from BEFORE it even occurs!
Unlike alternatives that merely capture exceptions, Loupe also logs trace events and performance metrics. Loupe shows what preceded each error so you can quickly pinpoint root causes and resolve bugs and bottlenecks
Get the whole story, not just the headlines
Loupe does much more than just capture errors, it also records what led up to each error. Loupe's detailed event traces and application metrics help pinpoint the root causes of those tricky errors that are hard to reproduce.
Magnify what matters
Loupe tracks every error, but what if you only care about errors in your production environment? No problem! Loupe understands release types, environments and promotion levels so that you can filter noise and focus attention on just the errors you care about.
Track error rates and usage
By tracking error rates and usage across time and application versions, Loupe helps you make better decisions about when your software is ready to ship.
Streamline your customer support
Loupe's full-text search makes it easy to find all the errors associated with a particular user, computer or error message. Loupe also aids customer support by tracking issue status, assignments and workarounds.
Write better software, faster
Most importantly, Loupe helps software developers identify, analyze and resolve software defects faster. New errors are easily reviewed and assigned and resolved issues are automatically re-opened if they reoccur. Loupe saves time by providing all the relevant details needed to pinpoint the root cause of each error.
Work smarter, not harder
Loupe includes some clever features to ensure you don't drown in error reports — even if your apps are deployed on thousands of computers and/or generate millions of error messages.
Stay informed, not overloaded
Smart email alerts notify you about important events without swamping your inbox. Here are a few examples of typical notification rules for various roles: Tech Lead - First occurrence of a new error in a release version of app Y greater than 3.5 DevOps Engineer - Every occurrence of a critical error in the production environment QA Lead - Every time an issue is resolved for any app in product Z
Customer Experience Improvement Program (CEIP)
Loupe can be used by small- and mid-size teams to create a customer experience improvement that collects information about how your customers use your programs and about some of the problems they encounter. Loupe makes it easy to collect and analyze this data to improve your products and features customers use most often and to help solve problems.
Troubleshoot in real-time
Loupe normally streams logs buffered through local storage ensuring no data is lost, even if the network goes down. In addition, it can also connect directly to live server or desktop applications via TCP sockets to display log messages in real-time with sub-second latency.
Loupe is engineered for the real world
The Loupe team has been writing production application logging code for over 15 years. Our #1 design principle is: first, do no harm. Loupe will never crash or hang your app. And Loupe keeps logging even on your worst day.
Be up and running in minutes
All it takes is adding a nuget package and a couple lines of code to your project. Lots of insight for very little effort - Loupe supports all .NET applications and tightly integrates with ASP.NET, MVC, WebAPI, Entity Framework and the .NET Framework for a wealth of automatic logging. Loupe captures all the logging you're already doing via System.Diagnostics, Console, log4net, Nlog, and it also integrates easily with your homegrown logging system.
Loupe Technical FAQ
What makes Loupe different from other tools?
Loupe combines logging with error reporting. This unique combination of centralized log management with automated error analysis saves you time pinpointing the root cause of bugs and bottlenecks.
Loupe is also extremely efficient and reliable in production. All Loupe data is buffered first to memory then to local disk so it is super fast and nothing is lost even if the network goes down.
Finally, the Loupe logging libraries and log viewer are free. Even if you never purchase a Loupe subscription, you can view your logs locally.
Can I try Loupe before I buy it?
Yes! We encourage you to give Loupe a try. It’s completely free for 30 days, no credit card required. And, even if you never purchase a Loupe Subscription or Loupe Server license, you can continue to use our logging libraries and log viewer for free, forever.
Is it difficult to integrate Loupe with my software?
Not at all. The simple setup captures unhandled errors as well as any existing logging you're already doing and it takes just a couple minutes.
How safe is Loupe? Will it slow down my application, use a lot of memory or disk?
Loupe was designed to do no harm from day one. It's safe and efficient in highly multithreaded or single threaded applications and does the vast majority of its work on background threads so as to cause negligible latency to your applications. It makes efficient use of memory and writes data to compressed files to mimimize disk consumption. Moreover, Loupe manages local storage consumption within configurable storage limits and can automate transmission of logs by email or web service calls. Log transmission is restartable, transactional and tolerant of intermittent network connectivity.
What type of applications does Loupe work with?
Loupe is well suited to web applications, desktop applications and services.
Loupe captures all the logging you're already doing via System.Diagnostics, Console, log4net, Nlog, and it also integrates easily with your homegrown logging system.
What are the key parts of Loupe?
Loupe consists of three parts:
- Loupe Agent is a lightweight .NET assembly that runs in-process within your applications safely and efficiently collecting errors, events, metrics and configuration information.
- Loupe Desktop is a desktop application used to manage and analyze Loupe logs.
- Loupe Server is a powerful web application brings your data and your team together.
