The slab cache is used by the kernel to store data structures that are used internally. Slab: This is the amount of memory being used by the kernel slab cache.Shared memory is memory that is shared between multiple processes. Shmem: This is the amount of memory being used for shared memory.This includes files that are mapped into memory using the mmap system call. Mapped: This is the amount of memory that is mapped into the page cache.Anonymous pages are pages that are not associated with any file. AnonPages: This is the amount of memory being used by anonymous pages.Writeback: This is the amount of memory that is currently being written to disk.Dirty: This is the amount of memory that is waiting to be written to disk.SwapFree: This is the amount of swap space that is not currently being used.SwapTotal: This is the total amount of swap space on the system.Inactive: This is the amount of memory that is not currently being used but is still available to processes.Active: This is the amount of memory that is currently being used by active processes.The page cache is used by the kernel to store recently accessed data in memory so that it can be quickly accessed again. Cached: This is the amount of memory being used by the page cache.

Buffers are used by the kernel to store data that is being read from or written to disk. Buffers: This is the amount of memory being used by buffers.MemFree: This is the amount of physical memory that is not being used by the system.MemTotal: This is the total amount of physical memory on the system.Here is a breakdown of some of the information provided in each line of /proc/meminfo: To view the “/proc/meminfo” file, open a terminal and type:.The first few lines provide summary information about memory usage, while the remaining lines provide more detailed information about specific areas of memory. Each line in the file represents a different aspect of memory usage. The /proc/meminfo file provides detailed information about memory usage on the Linux system. This method again relies on the terminal to display the memory usage. Method 3: Using the “cat” /proc/meminfo Command and finally, the command that is being executed.time each task or process has been running for.overall memory usage by each task in percentage.CPU usage by each process in percentage.S which is for displaying the process state.
