Allows JDBC resources to be monitored. You can see when java.sql objects are being opened and closed and can see the line of code where a resource that is still open was originally opened.
FIDe is a software-based fault injector designed to validate Fault-Tolerant mechanisms and techniques used by applications. It was first used to measure database recovery coverage and costs, but can be used to test and validate ordinary applications.
A light-weight malloc replacement (a shim), for developers, with the goal of being worth it's low overhead in (early) releases of a program. Optional routines allow the program to display allocation information about memory allocations.
The GDB (GNU debugger) RSP (remote serial protocol) allows remote debugging of embedded software. This project offers source code of monitors so the developer only needs to burn flash EPROMs once, then use serial communication to download/debug.

Jylog is a (JPDA) Java Platform Debugger Architecture based logger, Jylog eliminates the need for writing any log statement in the program. one can define the logging information using Jylog swing GUI and Jylog extracts the information from JVM at runtime
DMACS: a feature-rich debugger that can be potentially used with any C++ program on any platform. Designed with game programming in mind, it supports logging, an enhanced assert macro, state saving and loading, stack-watching, and more.
Given a GCC "gmon.out" file (or output from the GNU tool gprof), generate an HTML version with one page per call graph, including hyperlinks and (later) graphical analysis.
the omega xvi project is a javascript debugger written in javascript. it can debug code, execute blocks of code or entire applications, as well as detect variables. because of its javascript nature, it can be run through a webpage, online.
Bean Bowl is the a fun and useful Java lab, allowing you to play around with Java classes and objects using direct manipulation techniques instead of writing long main() methods. Use it either as an application or as a GUI component framework for you own
Gscope is a software oscilloscope library build using the GTK and GNOME toolkits. Gscope can be used to monitor, display and debug various types of "real-time" data. Additionally, the scope can be used for graphing file data that is in a tuple format.
VisLua is a full featured IDE for the Lua scripting language written in Lua. VisLua supports full context debugging, syntax highlighing, and many other advanced IDE features.
NJAMD (Not Just Another Malloc Debugger) protects against all common dynamic memory bugs, without even relinking your executable. It also provides stack trace information, and eventually will include a full GUI interface. NJAMD NEEDS YOUR HELP!
Java-program to read, modify and execute class-files. a real java VM written in java or a decompiler for class-files is possible (and partially working)
ANSIMD (Ansi Memory Debugger) is a compact, powerful and flexible debugging
facility, completely configurable at runtime, that detects automatically a
large class of problems related to memory management. It is portable and
requires low resources.
xdProf is a tool that captures and analyzes stack traces sent at a fixed interval from Java Virtual Machines in a distributed system. The xdProf client uses a C/C++ Java Virtual Machine Profiling Interface (JVMPI) library and works on many platforms.
httptrace - TCP/HTTP trace utility (for Java or Win32/jview.exe)
Listens on a TCP/IP port, redirects data to another port and writes traces.
Several options (search for patterns, ...).
PHP Profiler is both a Zend extension and module capable of generating profiling information (function call statistics) for PHP applications on the server side. No PHP code has to be changed, although the profiler data is available to your scripts.
Clint is a testbed for static source-code checking techniques. It is currently designed to check C++ for common programmer errors and suggest improvements.
Parallelized GDB: a tool for debugging parallel programs written in MPICH.
Written in C++ and on the brink (hopefully) of usability. Please help develop!

memory tracker that redefines some memory allocation functions like malloc or strdup (and glib functions too) to log where memory is used.
OpenTNF is a system-level tracing facility for capturing and presenting diagnostic information and performance metrics. Linux/Intel (kernel 2.2.x) is the initial target platform. The OpenTNF project is seeking developers for ports to other platforms.
