Processes
- r: How many processes are waiting for CPU time.
- b: Wait Queue - Process which are waiting for I/O (disk, network, user input,etc..)
Memory
- free: Idle Memory
- buff: Memory used as buffers, like before/after I/O operations
- cache: Memory used as cache by the Operating System
- (Ignored)swpd: shows how many blocks are swapped out to disk (paged). Total Virtual memory usage.
Swap
- si: How many blocks per second the operating system is swapping in. i.e Memory swapped in from the disk (Read from swap area to Memory)
- so: How many blocks per second the operating system is swaped Out. i.e Memory swapped to the disk (Written to swap area and cleared from Memory)
IO
- bi: Blocks received from block device - Read (like a hard disk)
- bo: Blocks sent to a block device - Write
System
- in: The number of interrupts per second, including the clock.
- cs: The number of context switches per second.
CPU
- us: percentage of cpu used for running non-kernel code. (user time, including nice time)
- sy: percentage of cpu used for running kernel code. (system time - network, IO interrupts, etc)
- id: cpu idle time in percentage.
- wa: percentage of time spent by cpu for waiting to IO.
