DTrace meets JavaScript
Brendon Chase writes:
There are a few good JavaScript debuggers out there and a few are integrated with popular IDEs but a new project, code-named Helper Monkey, led by Sun Microsystem's employee, Brendan Gregg, caught my eye. Project Helper Monkey brings the power of DTrace, a tracing framework originally created by Sun for Solaris to JavaScript. Gregg says he is doing this by utilising user statically defined tracing interface(USDT) probes to the Spider Monkey JavaScript engine, used by Mozilla-based browsers. According to Gregg he has added probe calls to "observe JavaScript function calls, object creation, and the destruction(garbage collection, and script execution. I've also written several DTrace scripts to report probe activity".
