DTrace features and specs

Comprehensive Observability
DTrace provides a comprehensive view of system behavior by observing metrics across various layers, including the operating system, hardware, and applications.
Real-time Analysis
It allows for real-time tracing and diagnosing, which is critical for identifying performance bottlenecks as they occur.
Low-Overhead
DTrace is designed to have minimal impact on system performance, making it suitable for use in production environments.
Dynamic Instrumentation
It can dynamically enable and disable probes in a live system, which allows detailed monitoring without restarting the system or applications.
Cross-platform Support
Originally developed for Solaris, DTrace has been ported to other operating systems like FreeBSD and MacOS, extending its usability.

Possible disadvantages of DTrace

Complexity
DTrace's powerful capabilities can make it complex to learn and use effectively, especially for those unfamiliar with its scripting language.
Limited to Supported Platforms
DTrace is not available on all operating systems, limiting its use to those systems that support it.
Security Concerns
Since DTrace can access many parts of the system, there are potential security implications if not properly managed and secured.
Limited GUI Tools
While DTrace is command-line oriented, it lacks advanced built-in graphical interfaces, which can be a drawback for users who prefer visual data representation.
Potential for Misuse
Improper use of DTrace can lead to system instability or performance problems, particularly if inexperienced users enable extensive probes.

Valgrind features and specs

Comprehensive Memory Debugging
Valgrind provides thorough memory debugging and memory leak detection, identifying use-after-free and other memory errors in applications.
Profiling Capabilities
In addition to identifying memory issues, Valgrind offers basic CPU profiling, allowing developers to assess performance bottlenecks.
No Source Code Changes Required
Valgrind can be used without altering the source code, making it easy to integrate into existing projects for debugging purposes.
Supports Multiple Languages
Valgrind supports a variety of programming languages, including C, C++, and others, making it versatile across different codebases.
Wide Platform Support
It is available on many platforms, including Linux and macOS, providing flexibility to developers working in different environments.

Possible disadvantages of Valgrind

Performance Overhead
Valgrind significantly slows down program execution, often by a factor of 10 to 30 times, which can make testing large applications more time-consuming.
Limited Windows Support
Valgrind has no native Windows support, requiring developers to use alternate solutions or run it in a Linux environment.
Complexity with Multithreading
Debugging multithreaded applications can be complex, and Valgrind's tools may struggle with race conditions and other threading issues.
Heavy Resource Usage
Running applications under Valgrind can consume significant system resources, impacting other processes and the overall system performance.
Steep Learning Curve
The tool has a steep learning curve, especially for users new to debugging tools, which can require additional time for proficiency.

Mactop
I believe that macOS still ships with DTrace; Xcode Instruments was originally built on top of it. https://dtrace.org (Some people find it easier to write a one-line script that reports the timings that they need; I don't know if it helps you.). - Source: Hacker News / about 1 year ago

Why does Debian change software?
Hello, as always: imho (!) I remember this incident - if my memory doesn't trick me: it was openssl which accessed memory it didn't allocated to collect randomness / entropy for key-generation. And valgrind complained about a possible memory-leak - its a profiling-tool with the focus on detecting memory-mgmt problems. * https://valgrind.org/ instead of taking a closer look / trying to understand what exactly went... - Source: Hacker News / 9 days ago
Understanding the Odin Programming Language
Odin has a builtin heap allocator that works the same way you would expect any other high-level language to do memory allocation–it's just that you have to free the memory yourself. Plus, Odin's built in `context` system makes it really easy to change what kind of allocator is used for different sections of code. For my use cases, I've never needed any more than a heap and an arena, detailed in this talk:... - Source: Hacker News / 6 months ago
Intel Announces Retirement of CEO Pat Gelsinger
Dunno, who says a lot of effort was put into Rosetta 2? It's mostly something that was needed in the first few years so you could run Chrome and Photoshop, but those have been ported now. It's mostly useful for running WINE but that's not super common outside games. That said, a binary recompiler has a lot of uses once you have one: https://valgrind.org. - Source: Hacker News / 6 months ago
