PRTG Catches Network Issues Before They Cause Downtime
Threshold-based alerts flag problems early, so your team can act before users notice, not after.
Reactive troubleshooting usually means hearing about a problem from frustrated users, not your monitoring tool. PRTG sets threshold-based alerts across devices, servers and applications, notifying your team by email, SMS or push the moment a metric crosses a set limit. That means catching a failing disk or overloaded server before it becomes an outage and getting time back from firefighting. Start a free trial and set your first alerts today.

Cloud SQL Enterprise Plus delivers near-zero downtime with 35 days of point-in-time recovery. Supports MySQL, PostgreSQL, and SQL Server.
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
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.
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

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.
A recreation of Microsoft's Visual Basic that runs and compiles for/in Linux. We've decided that VB4Linux will be programmed in C. We will probably be beginning sometime within the next week or so... Still looking for developers! Thx!
