DTrace vs ltrace

Struggling to choose between DTrace and ltrace? Both products offer unique advantages, making it a tough decision.

DTrace is a Os & Utilities solution with tags like tracing, troubleshooting, debugging.

It boasts features such as Dynamic instrumentation of running production systems, Minimal overhead and performance impact, Support for multiple programming languages, Real-time diagnostics, Root cause analysis and pros including Powerful troubleshooting capabilities, Low overhead, Easy to use, Integrated into Solaris and other OSes.

On the other hand, ltrace is a Development product tagged with library, debugging, tracing, dynamic-linking.

Its standout features include Intercepts and records dynamic library calls made by a process, Can trace calls made by programs to shared libraries, Helps debug issues caused by dynamic linking, Shows parameters passed to library functions and return values, Tracks time spent in each call, and it shines with pros like Lightweight and easy to use for debugging, Does not require modifying or recompiling the target program, Works on most Linux distributions without special setup, Can trace proprietary programs where source code is unavailable.

Product Overview

DTrace

Description: 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

Description: 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.
