SystemTap provides free software (GPL) infrastructure to simplify the gathering of information about the running Linux system. This assists diagnosis of a performance or functional problem. SystemTap ... [More] eliminates the need for the developer to go through the tedious and disruptive instrument, recompile, install, and reboot sequence that may be otherwise required to collect data. SystemTap provides a simple command line interface and scripting language for writing instrumentation for a live running kernel and user-space applications. We are publishing samples, documentation, as well as enlarging the internal "tapset" script library to aid reuse and abstraction. [Less]

BTrace is a safe, dynamic tracing tool for the Java platform. BTrace can be used to dynamically trace a running Java program (similar to DTrace for OpenSolaris applications and OS). BTrace dynamically ... [More] instruments the classes of the target application to inject tracing code ("bytecode tracing"). Tracing code is expressed in Java programming language. There is also integration with DTrace for the OpenSolaris platform. [Less]

Lets you see your Python program's execution as a tree of function invocations, each tree node exposing the real time, and CPU time (user/sys) of that call. This project consists of two main ... [More] components: A Python tracer that can run your Python programs (much like "cProfile" and friends). A Gtk+ based GUI that can show the trace results. It uses a tiny auxiliary library written for it "graphfile" to allow append-only writing and reading static DAG's directly from file without reading it whole into memory at any stage. [Less]
