获取cpu的逻辑数量

python import psutil print(psutil.cpu_count()) # 12

获取CPU的物理核心数

python import psutil print(psutil.cpu_count(logical=False)) # 6

结果为6，说明6核超线程，12的话说明是12核非超线程

统计CPU的用户／系统／空闲时间

python import psutil print(psutil.cpu_times()) # scputimes(user=149649.15625, system=107455.375, idle=3217150.65625, interrupt=4962.5, dpc=3208.484375)

查看cpu的使用率

python import psutil for x in range(3): # interval：表示每隔0.5s刷新一次 # percpu：表示查看所有的cpu使用率 print(psutil.cpu_percent(interval=0.5, percpu=True)) """ [17.6, 3.1, 3.1, 12.5, 12.5, 3.1, 21.9, 51.5, 12.5, 9.4, 6.2, 9.4] [12.5, 3.1, 28.1, 3.1, 12.5, 15.6, 21.9, 21.9, 21.9, 0.0, 6.2, 3.1] [6.1, 0.0, 3.1, 3.1, 0.0, 21.9, 0.0, 34.4, 12.5, 0.0, 9.4, 0.0] """ # 我这里cpu的逻辑数量是12.所以每个里面有12个元素

获取物理内存信息

python import psutil print(psutil.virtual_memory()) # svmem(total=17100566528, available=8526913536, percent=50.1, used=8573652992, free=8526913536) # total：内存总大小 # available：剩余可用 # percent：已经使用的内存占总内存的比例 # used：已经使用的内存

获取交换内存信息

python import psutil print(psutil.swap_memory()) # sswap(total=18252959744, used=12977037312, free=5275922432, percent=71.1, sin=0, sout=0)

关于物理内存和交换内存之间的关系

物理内存

就是实际的内存条提供的临时数据存储空间，在windows上右键点击计算机，显示属性时，上面显示的安装内存(RAM)，就是电脑的物理内存。这些内存是实际存在的，在你不给机器增加内存条的时候是不会改变的

交换内存

交换内存是专门用来临时存储数据的，通常在页面调度和交换进程数据时使用。相当于在进行内存整理的时候，会先把部分数据放在硬盘的某个地方，类似我们整理衣柜，衣服一多直接整理会很麻烦，因此会先把部分衣服放在其他地方，等衣柜里的衣服整理完了再把放在其他地方的衣服拿回来。这个其他地方放在计算机中则代表硬盘的某个地方，也就是我们所说的交换区。通常当使用交换内存时，以为这物理内存不足，正所谓衣柜，如果衣服不多那就没必要拿出部分衣服放在其他地方，直接在衣柜里就能解决了

虚拟内存

首先，如果想要操作文件，可执行程序等等，那么首先要把它们从磁盘上读取到内存中，因此cpu除了自己的那一部分小小的空间外，要想操作数据，只能操作内存里的数据。但是当内存不够了，那么便会在硬盘上开辟一份虚拟内存，将物理内存里的部分数据放在虚拟内存当中。硬盘的空间很大，即使普通电脑安装的固态硬盘也有一百个G，因此可以拿出一部分充当虚拟内存。不过虚拟内存虽说是内存，但毕竟在硬盘上，速度绝对和cpu直接从物理内存里读取数据的速度相差甚远。这也是为什么那些大型网站将经常被访问的一些数据放在redis缓存里，而不是放在硬盘或者数据库上

查看磁盘信息

可以通过psutil获取磁盘分区、磁盘使用率和磁盘IO信息

python import psutil print(psutil.disk_partitions()) """ [sdiskpart(device='C:\\', mountpoint='C:\\', fstype='NTFS', opts='rw,fixed'), sdiskpart(device='D:\\', mountpoint='D:\\', fstype='NTFS', opts='rw,fixed'), sdiskpart(device='E:\\', mountpoint='E:\\', fstype='NTFS', opts='rw,fixed'), sdiskpart(device='F:\\', mountpoint='F:\\', fstype='NTFS', opts='rw,fixed')] """ # 可以看到一共有四个盘符，fstype表示文件系统格式是NTFS，opts中的rw表示可读写

查看某个磁盘使用情况

python import psutil print(psutil.disk_usage("C:\\")) # sdiskusage(total=239217770496, used=66969640960, free=172248129536, percent=28.0)

获取网络读写字节/包的个数

python import psutil print(psutil.net_io_counters()) # snetio(bytes_sent=180501149, bytes_recv=1192812614, packets_sent=775155, packets_recv=1090820, errin=0, errout=0, dropin=0, dropout=0)
