Question

linux下 如何看每个CPU的使用率

Answer 1

1、输入 top -bn1 (b控制输出格式为文本格式，非交互格式)
　　[mysql@longxibendi.host]$ top -bn1
2、输入top ,进入交互模式，为下一步设置输出格式做准备
　　[mysql@longxibendi.host]$ top
3、然后输入1
4、就可以看到多个CPU利用率了：
　　top - 21:40:51 up 25 days, 9:32, 1 user, load average: 0.15, 0.30, 0.33
　　Tasks: 101 total, 1 running, 96 sleeping, 0 stopped, 4 zombie
　　Cpu0 : 0.8% us, 0.3% sy, 0.0% ni, 98.4% id, 0.3% wa, 0.0% hi, 0.0% si
　　Cpu1 : 1.1% us, 0.2% sy, 0.0% ni, 98.6% id, 0.1% wa, 0.0% hi, 0.0% si
　　Cpu2 : 0.5% us, 0.1% sy, 0.0% ni, 99.4% id, 0.0% wa, 0.0% hi, 0.0% si
　　Cpu3 : 0.4% us, 0.1% sy, 0.0% ni, 99.5% id, 0.0% wa, 0.0% hi, 0.0% si
　　Cpu4 : 0.3% us, 0.1% sy, 0.0% ni, 99.5% id, 0.0% wa, 0.0% hi, 0.0% si
　　Cpu5 : 0.3% us, 0.1% sy, 0.0% ni, 99.6% id, 0.0% wa, 0.0% hi, 0.0% si
　　Cpu6 : 0.3% us, 0.1% sy, 0.0% ni, 99.6% id, 0.0% wa, 0.0% hi, 0.0% si
　　Cpu7 : 0.2% us, 0.1% sy, 0.0% ni, 99.7% id, 0.0% wa, 0.0% hi, 0.0% si
