"Linux Indicators" memory

1: Memory utilization

indicator name	indicator meaning	units	acquisition mode (Linux)	acquisition mode (Windows)
AGT. Available memory		GB	Get memavailable through/proc/meminfo; if memavailable is not shown in/proc/meminfo, Then memavailable=memfree+buffers+cached	Description The calculation method is (total memory-amount of RAM used). obtained by WindowsAPI GlobalMemoryStatusEx.
AGT. Memory utilization		%	Description Obtained by/proc/meminfo file, (memtotal-memavailable)/memtotal	Description The calculation method is (amount of memory used/Total *100%).
AGT. Idle memory	 	GB	Description:	temporarily not supported
agt". Buffers occupancy	 	 GB	Description: obtained by/proc/meminfo. The user can view the KiB mem:buffers value through the top command.
AGT. Cache usage		GB	Description Obtained through/proc/meminfo. The user can view the KiB swap:cached mem value from the top command.

A program that occupies a large memory does not necessarily consume a lot of CPU resources, and a program that takes up a large CPU does not necessarily cost too much memory. A program's high CPU usage can affect the operation of other programs. A program that consumes too much memory can affect the overall performance of the machine.

Uffers is the buffer size used to make a block device, and he only records the metadata of the filesystem and tracking in-flight pages.

Cached is used to buffer files.

That is to say: buffers is used to store, what content inside the directory, permissions and so on. and cached is used directly to memorize the files we open.
