# Memory Meminfo Displays system memory usage. There are several graphs displayed including the following: ## **Memory Active / Inactive** Displays the amount of memory currently in use and not yet used.

## **Memory commited** Displays the total amount of memory that has been allocated by the operating system for use by a particular application or process.

## **Memory Active / Inactive Detail** Display further explanation on active and inactive memory allocation.

## **Memory Writeback and Dirty** Display the process of writing unsaved data from memory to long-term storage such as disk.

## **Memory Shared and Mapped** Displays the amount of memory shared across multiple processes and the amount of memory mapped to virtual addresses.

## **Memory Slab** Display the memory allocated by the kernel to store internal data structures used for resource management.

## **Memory Vmalloc** Displays the virtual memory dynamically allocated by the kernel for a specific use.

## **Memory Bounce** Displays memory usage associated with switching between different memory addresses.

## **Memory Anonymous** Displays memory allocated by the process but not associated with files.

## **Memory Kernel / CPU** Displays the memory used by the operating system kernel to store code, data structures, and the kernel stack.

**Memory HugePages Counter** Displays the number of large memory pages used in the system, large memory is used to reduce memory management overhead on systems with large amounts of memory.

## **Memory Huge Pages Size** Displays the page size of the large memory used in the system.

## **Memory Direct Map** Displays a direct mapping between physical memory addresses and virtual memory addresses in the system.

## **Memory Unevictable and MLocked** Displays memory usage that cannot be avoided or moved by the operating system, as well as memory that is locked in physical memory and will not be swapped out.

## **Memory NFS** Displays memory usage related to the network file system, including buffers or caches for file operations involving network resources.
