Where can I find documentation explaining the meaning of entries in /proc/meminfo and /proc/vmstat files? I looked up on the web and the man page of proc but could not find much. Many entries are self explanatory but some are not.

Preferably, looking for documentation that indicates how to interpret the various values in those entries and what it means for instance if some values are too high or too low.

/proc/meminfo:

https://www.kernel.org/doc/html/latest/filesystems/proc.html#meminfo

/proc/vmstat:

There's very little documentation available for it:

https://www.kernel.org/doc/html/latest/admin-guide/mm/transhuge.html

And if you can read C:

https://github.com/torvalds/linux/blob/master/mm/vmstat.c
