About Btrace
BTrace is an open source dynamic tracing tool built for the Java platform. Its core value is safety: it allows runtime instrumentation of JVM applications while enforcing constraints that reduce the risk of destabilizing target processes. This makes it useful for production debugging, performance analysis, and incident response when restarting or redeploying an application is costly.
With BTrace, engineers can attach tracing scripts to running Java processes and observe method calls, timings, exceptions, and other runtime signals. Instead of adding temporary logging and rebuilding services, teams can collect focused diagnostics directly from live systems. That shortens time-to-resolution for hard-to-reproduce issues and improves operational visibility.
The project fits naturally into a broader observability workflow alongside logs, metrics, and profiling tools. It is especially relevant for JVM-heavy environments where low-friction diagnostics are critical. For teams maintaining complex Java services, BTrace provides a practical path to deeper runtime insight while prioritizing controlled, safe instrumentation.
