A safe, dynamic tracing tool for the Java platform
Version
1.2
Quick Summary
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 instruments the classes of the target application to inject tracing code ("bytecode tracing").
Building BTrace
Setup
You will need the following applications installed
Build
cd <btrace>/make
ant dist
The binary dist packages can be found in <btrace>/dist as the *.tar.gz and *.zip files
Using BTrace
Installation
Explode a binary distribution file (either *.tar.gz or *.zip) to a directory of your choice
You may set the system environment variable BTRACE_HOME to point to the directory containing the exploded distribution.
You may enhance the system environment variable PATH with $BTRACE_HOME/bin for your convenience.
Running
<btrace>/bin/btrace <PID> <trace_script>will attach to the java application with the given PID and compile and submit the trace script<btrace>/bin/btracec <trace_script>will compile the provided trace script<btrace>/bin/btracer <compiled_script> <args to launch a java app>will start the specified java application with the btrace agent running and the script previously compiled by btracec loaded
