The proc filesystem is a pseudo-filesystem which provides an interface to kernel data structures.
TLDR Cont.
The proc filesystem (procfs) is a special filesystem in Unix-like operating systems that presents information about processes and other system information in a hierarchical file-like structure, providing a more convenient and standardized method for dynamically accessing process data held in the kernel than traditional tracing methods or direct access to kernel memory.
Fields
Memory
/proc/<pid>/stat: Status information about the process.
/proc/<pid>/statm: Provides information about memory usage, measured in pages.
/proc/<pid>/maps: A file containing the currently mapped memory regions and their access permissions.
/proc/<pid>/smaps: Shows memory consumption for each of the process's mappings.
/proc/<pid>/status: Provides much of the information in /proc/<pid>/stat and /proc/<pid>/statm in a format that's easier for humans to parse.
