We don't like to admit it, but our applications have errors. Some of these are our fault, some are due to bad configuration or a problem with the host environment. But what if we were notified about these errors as they happen? What if we could fix the problem before the user told us about it? RayGun provides us with the tools to do this. From installation to configuration and beyond. I'll show you how you can use RayGun in your applications.
