The Gems of Moreutils
For execsnoop, people running systems with DTrace can find the same:

On macOS Monterey+ you'll probably have to install the Kernel Debug Kit per:

The Linux variant was written Brendan Gregg (who previous did a lot of work on Solaris, where DTrace was created):

Track what process modify file
It's not a library you can use but you might be able to take inspiration from something like opensnoop.

Which kernel functions are called upon page cache accesses?
I have an application and I'd like to measure its page cache hit/miss numbers. I found this tool called cachestat by Brendan Gregg, which uses the ftrace tool to count the number of 4 specific functions (mark_page_accessed(), mark_buffer_dirty(), add_to_page_cache_lru(), and account_page_dirtied()) to find out the total number of page cache accesses and page cache misses. Detailed information can be found here, but basically, total number of page cache accesses and page cache misses can be calculated as below:

Using Distributed Tracing in Microservices Architecture
Program(Process) Tracing (ptrace) Tools: Establishes tracing operation during the execution of the application. Contains the traces of the index of instructions executed and the data referenced during execution. These are greatly used by developers for debugging purposes. Some examples of ptrace tools are, Strace, Ltrace, Opensnoop, and Valgrind Lackey.

Wireshark & tcpdump: A Debugging Power Couple
To begin with Wireshark, visit their official website for the download. The installation process is straightforward, but attention should be paid to the installation of command-line tools, which may require separate steps. Upon launching Wireshark, users are greeted with a selection of network interfaces as seen below. Choosing the correct interface, such as the loopback for local server debugging, is crucial for capturing relevant data.

Non-IP networking
If you're very curious as to what is really going on under the hood, I recommend you familiarize yourself with port mirroring for your switch platform of choice, and then use a laptop in promiscuous mode to capture traffic using Wireshark. Failing that, hire a network engineer to interview one of their sales engineers or architects, and have them explain it to you.

How to implement SSL/TLS pinning in Node.js
A great way to test the effectiveness of a pinning implementation is by simulating an MITM attack. Tools like Mitmproxy or Wireshack allow us to create a test environment to monitor, intercept, and proxy network requests for a test host.

Network+ Wireshark classification question
Obviously based on the question you know the answer is a Wireshark-like software and it boils down to how you classify Wireshark. My issue is that Wikipedia refers to it as a Packet Analyzer, Varonis refers to it as a Packet Sniffer, Wireshark refers to itself as a Network Protocol Analyzer, Kali documentation refers to it as a Network Sniffer, Wireshark's README refers to itself as a Network Analyzer OR Sniffer...
What are some alternatives?
mitmproxy - An interactive TLS-capable intercepting HTTP proxy for penetration testers and software developers.
Sysdig - Linux system exploration and troubleshooting tool with first class support for containers
pyshark - Python wrapper for tshark, allowing python packet parsing using wireshark dissectors
strace - strace is a diagnostic, debugging and instructional userspace utility for Linux
mtr - Official repository for mtr, a network diagnostic tool
httpstat - curl statistics made simple
Dripcap
grml - Grmls core configuration files for zsh, vim, screen…
