    Question Meaning of some infos from top and vmstat?


    I'm having a hard time finding what some of the fields mean when
    running "top" and "vmstat" on a Debian host:

    ====== top ===============
    Cpu(s): 78.8% us, 18.7% sy, 0.0% ni, 0.7% id, 0.3% wa, 0.5% hi, 1.0%
    Mem: 1015484k total, 993344k used, 22140k free, 76920k buffers
    Swap: 514040k total, 101032k used, 413008k free, 208496k cached
    => What do wa/hi/si mean?
    => What is "cached" swap?
    ====== vmstat ===============
    procs -----------memory---------- ---swap-- -----io---- --system--
     r  b   swpd   free   buff  cache   si   so    bi    bo   in    cs us
    sy id wa
     9  0      0  55588  87548 329824    0    0   166   292  369   896 69
    17  5  9
    => What do bi/bo mean for "io"? Bytes in/out?
    => What do in/cs mean for "system"?

    Thank you.

    These are the meanings:-

    bi: Blocks received from a block device (blocks/s).
    bo: Blocks sent to a block device (blocks/s).
    in: The number of interrupts per second, including the clock.
    cs: The number of context switches per second.

    date; cd~; unzip; touch;
    strip; finger; mount; gasp;
    yes; uptime; umount;
