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"). ## Credits * Based on [ASM](http://asm.ow2.org/) * Powered by [JCTools](https://github.com/JCTools/JCTools) * Powered by [hppcrt](https://github.com/vsonnier/hppcrt) * Optimized with [JProfiler Java Profiler](http://www.ej-technologies.com/products/jprofiler/overview.html) ## Building BTrace ### Setup You will need the following applications installed * [JDK](http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html) (preferrably JDK8) * [Git](http://git-scm.com/downloads) * [Gradle](http://gradle.org) * (optionally) [Ant](http://ant.apache.org/bindownload.cgi) * (optionally) [Maven3](http://maven.apache.org/download.cgi) ### Build #### Gradle ```sh cd <btrace> ./gradlew build ./gradlew buildDistributions ``` The binary dist packages can be found in `<btrace>/build/distributions` as the *.tar.gz, *.zip, *.rpm and *.deb files. #### Ant (legacy build) ```sh 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 Download a distribution file from the [release page](https://github.com/btraceio/btrace/releases/latest). Explode the 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. Or, alternatively, you may install one of the *.rpm or *.deb packages ### 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 For the detailed user guide, please, check the [Wiki](https://github.com/btraceio/btrace/wiki/Home). ### Maven Integration The [maven plugin](https://github.com/btraceio/btrace-maven) is providing easy compilation of __BTrace__ scripts as a part of the build process. As a bonus you can utilize the _BTrace Project Archetype_ to bootstrap developing __BTrace__ scripts. ## Mailing lists These mailing lists are hosted at **http://librelist.com** * **btrace.users@librelist.com** * **btrace.dev@librelist.com** * **btrace.commits@librelist.com** ## Contributing - !!!
