summary: Learn how to identify errors in your application and best practice for logging application errors.

Debugging

SilverStripe can be a large and complex framework to debug, but there are ways to make debugging less painful. In this guide we show the basics on defining the correct Environment Type for your application and other built-in helpers for dealing with application errors.

Performance

See the Profiling documentation for more information on profiling SilverStripe to track down bottle-necks and identify slow moving parts of your application chain.

Debugging Utilities

The [api:Debug] class contains a number of static utility methods for more advanced debugging.

:::php
Debug::show($myVariable);
// similar to print_r($myVariable) but shows it in a more useful format.

Debug::message("Wow, that's great");
// prints a short debugging message.

SS_Backtrace::backtrace();
// prints a calls-stack
