用python脚本查看电脑内存、CPU使用情况

有时为了对电脑、服务器做运行情况监控，需要获取内存、cpu的使用情况：

# 先下载psutil库:pip install psutil
# 下载地址  https://pypi.org/project/psutil/5.6.2/
import psutil


def getMemCpu():
    data = psutil.virtual_memory()
    total = data.total  # 总内存,单位为byte
    print('total',total)
    free = data.available  # 可用内存
    print('free',free)

    memory = "Memory usage:%d" % (int(round(data.percent))) + "%" + " "  # 内存使用情况
    print('memory',memory)
    cpu = "CPU:%0.2f" % psutil.cpu_percent(interval=1) + "%"  # CPU占用情况
    print('cpu',cpu)



if __name__ == "__main__":
    getMemCpu()
