Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

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:
* https://developer.apple.com/forums/thread/692444
The Linux variant was written Brendan Gregg (who previous did a lot of work on Solaris, where DTrace was created):

LINUX TOOLS PERFORMANCE for us !

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.

Does any one know how to make perf in wsl2, show the info like Cycles, Instructionis.
There are several tools that might go by the name 'perf', are you talking about this one? https://github.com/brendangregg/perf-tools

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.
