Dstat is a versatile replacement for vmstat, iostat and ifstat.


yum install -y dstat
# or
apt install -y dstat


# dstat --help
Usage: dstat [-afv] [options..] [delay [count]]
Versatile tool for generating system resource statistics

Dstat options:
  -c, --cpu              enable cpu stats
     -C 0,3,total           include cpu0, cpu3 and total
  -d, --disk             enable disk stats
     -D total,hda           include hda and total
  -g, --page             enable page stats
  -i, --int              enable interrupt stats
     -I 5,eth2              include int5 and interrupt used by eth2
  -l, --load             enable load stats
  -m, --mem              enable memory stats
  -n, --net              enable network stats
     -N eth1,total          include eth1 and total
  -p, --proc             enable process stats
  -r, --io               enable io stats (I/O requests completed)
  -s, --swap             enable swap stats
     -S swap1,total         include swap1 and total
  -t, --time             enable time/date output
  -T, --epoch            enable time counter (seconds since epoch)
  -y, --sys              enable system stats

  --aio                  enable aio stats
  --fs, --filesystem     enable fs stats
  --ipc                  enable ipc stats
  --lock                 enable lock stats
  --raw                  enable raw stats
  --socket               enable socket stats
  --tcp                  enable tcp stats
  --udp                  enable udp stats
  --unix                 enable unix stats
  --vm                   enable vm stats

  --plugin-name          enable plugins by plugin name (see manual)
  --list                 list all available plugins

  -a, --all              equals -cdngy (default)
  -f, --full             automatically expand -C, -D, -I, -N and -S lists
  -v, --vmstat           equals -pmgdsc -D total

  --bits                 force bits for values expressed in bytes
  --float                force float values on screen
  --integer              force integer values on screen

  --bw, --blackonwhite   change colors for white background terminal
  --nocolor              disable colors (implies --noupdate)
  --noheaders            disable repetitive headers
  --noupdate             disable intermediate updates
  --output file          write CSV output to file
  --profile              show profiling statistics when exiting dstat

delay is the delay in seconds between each update (default: 1)
count is the number of updates to display before exiting (default: unlimited)


  • dstat -cdngy 分别显示cpu、disk、net、page、system信息,默认是1s显示一条信息
  • dstat 5 每5秒显示一条
# dstat
You did not select any stats, using -cdngy by default.

    • siq:软中断次数
  • system
    • int:分别为系统的中断次数(interrupt)
    • csw:上下文切换(context switch)
