Projects tagged ‘java’ and ‘tracing’

I wanted to try my hand at raytracing. I know java. Here ya go.

A 3D image synthesis project written in Java using the ray tracing algorithm. Supports very basic materials and primitives. Focused on multithreaded and distributed rendering through a TCP/IP network.

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]

Hatch: A Stack-based Performance LoggerCheck out the GettingStarted page! Release Version 0.7 Release0Dot7 Snapshot Version 1.0-SNAPSHOT IntroductionLogging is still the simplest and most ... [More] popular way of tracing a program's execution. Even with many advanced tools at our disposal, we still lean toward simple I Am Here. style debugging. Hatch is a simple stack-based performance logger. Just by adding begin/end style calls into your code, you can trace how much time it is taking to perform a specific request. Example Output [135ms] request share purchase [5ms] validate purchase request [40ms] check account balances [39ms] synchronous balance request [30ms] read uncommitted share availability check [55ms] queue request [30ms] persist message to queue [15ms] write audit logFeaturesThreads can request tracing on a per-request basis, reducing clutter Enable or disable globally at runtime without restarting. Only log traces that meet specific criteria ("Only log requests that took over 1000ms during business hours.") Log to System.out or log4j (or extend the basic logger to log wherever you want, see AdvancedHatchUsage). More InformationPoke around the source to find out more. See the release notes history. [Less]
