DTrace vs ltrace: The Verdict

⚡ Summary:

DTrace: DTrace is a dynamic tracing framework created by Sun Microsystems for troubleshooting kernel and application problems on production systems in real time. It allows administrators, developers, and service personnel to concisely answer arbitrary questions about the behavior of the operating system and user programs.

ltrace: ltrace is a debugging utility that intercepts and records dynamic library calls which are called by an executed process. It can be used to trace calls made by programs to shared libraries and helps debug issues caused by dynamic linking.

Both tools serve their respective audiences. Compare the features, pricing, and user ratings above to determine which best fits your needs.
