top查看多cpu状态

1.top查看多cpu

# top
top - 14:09:24 up 155 days, 21:50,  1 user,  load average: 0.24, 0.18, 0.24
Tasks: 108 total,   1 running, 107 sleeping,   0 stopped,   0 zombie
Cpu(s):  0.0%us,  0.3%sy,  0.0%ni, 99.7%id,  0.0%wa,  0.0%hi,  0.0%si,  0.0%st
Mem:    501016k total,   490896k used,    10120k free,      244k buffers
Swap:   490488k total,   352784k used,   137704k free,    37312k cached

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
16316 mysql     20   0  709m 8092 2656 S  0.3  1.6  76:25.10 mysqld

    2 root      20   0     0    0    0 S  0.0  0.0   0:01.03 kthreadd
    3 root      RT   0     0    0    0 S  0.0  0.0   0:00.00 migration/0
    4 root      20   0     0    0    0 S  0.0  0.0   0:47.14 ksoftirqd/0
    5 root      RT   0     0    0    0 S  0.0  0.0   0:00.00 migration/0

按1 显示多cpu,再按1退出多cpu
按W,将配置保存为/root/.toprc文件
用已保存的模式打开top会显示多个cpu

2.一次静态输出多个cpu结果

# top -bn1  //查看所有进程-b是非交互模式,-n设置只输出一次信息
top – 16:51:56 up 8 days,  2:35,  1 user,  load average: 0.00, 0.01, 0.53
Tasks: 112 total,   1 running, 111 sleeping,   0 stopped,   0 zombie
Cpu0  :  0.0%us,  0.0%sy,  0.0%ni,100.0%id,  0.0%wa,  0.0%hi,  0.0%si,  0.0%st
Cpu1  :  0.0%us,  0.0%sy,  0.0%ni,100.0%id,  0.0%wa,  0.0%hi,  0.0%si,  0.0%st
Cpu2  :  0.0%us,  0.0%sy,  0.0%ni,100.0%id,  0.0%wa,  0.0%hi,  0.0%si,  0.0%st
Cpu3  :  0.0%us,  0.0%sy,  0.0%ni,100.0%id,  0.0%wa,  0.0%hi,  0.0%si,  0.0%st

3.持续查看某pid的cpu,内存使用量

# top -p 1122 //或watch "ps aux | grep 1122",此处假设pid为1122
