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.
