# 输出内存使用情况(以字节为单位)
import psutil
mem = psutil.virtual_memory()
print mem.total,mem.used,mem
print psutil.swap_memory() # 输出获取SWAP分区信息
# 输出CPU使用情况
cpu = psutil.cpu_stats()
printcpu.interrupts,cpu.ctx_switches
psutil.cpu_times(percpu=True) # 输出每个核心的详细CPU信息
psutil.cpu_times().user # 获取CPU的单项数据 [用户态CPU的数据]
psutil.cpu_count() # 获取CPU逻辑核心数,默认logical=True
psutil.cpu_count(logical=False) # 获取CPU物理核心数
# 输出磁盘信息
psutil.disk_partitions() # 列出全部的分区信息
psutil.disk_usage('/') # 显示出指定的挂载点情况【字节为单位】
psutil.disk_io_counters() # 磁盘总的IO个数
psutil.disk_io_counters(perdisk=True) # 获取单个分区IO个数
# 输出网卡信息
psutil.net_io_counter() 获取网络总的IO,默认参数pernic=False
psutil.net_io_counter(pernic=Ture)获取网络各个网卡的IO
# 获取进程信息
psutil.pids() # 列出所有进程的pid号
p = psutil.Process(2047)
p.name() 列出进程名称
p.exe() 列出进程bin路径
p.cwd() 列出进程工作目录的绝对路径
p.status()进程当前状态[sleep等状态]
p.create_time() 进程创建的时间 [时间戳格式]
p.uids()
p.gids()
p.cputimes() 【进程的CPU时间,包括用户态、内核态】
p.cpu_affinity() # 显示CPU亲缘关系
p.memory_percent() 进程内存利用率
p.meminfo() 进程的RSS、VMS信息
p.io_counters() 进程IO信息,包括读写IO数及字节数
p.connections() 返回打开进程socket的namedutples列表
p.num_threads() 进程打开的线程数
#下面的例子中,Popen类的作用是获取用户启动的应用程序进程信息,以便跟踪程序进程的执行情况
import psutil
from subprocess import PIPE
p =psutil.Popen(["/usr/bin/python" ,"-c","print 'helloworld'"],stdout=PIPE)
p.name()
p.username()
p.communicate()
p.cpu_times()
# 其它
psutil.users() # 显示当前登录的用户,和Linux的who命令差不多
# 获取开机时间
psutil.boot_time() 结果是个UNIX时间戳,下面我们来转换它为标准时间格式,如下:
datetime.datetime.fromtimestamp(psutil.boot_time()) # 得出的结果不是str格式,继续进行转换 datetime.datetime.fromtimestamp(psutil.boot_time()).strftime('%Y-%m-%d%H:%M:%S')
Python生成一个随机密码
#!/usr/bin/env python
# -*- coding:utf-8 -*-
import random, string
def GenPassword(length):
#随机出数字的个数
numOfNum = random.randint(1,length-1)
numOfLetter = length - numOfNum
#选中numOfNum个数字
slcNum = [random.choice(string.digits) for i in range(numOfNum)]
#选中numOfLetter个字母
slcLetter = [random.choice(string.ascii_letters) for i in range(numOfLetter)]
#打乱这个组合
slcChar = slcNum + slcLetter
random.shuffle(slcChar)
#生成密码
genPwd = ''.join([i for i in slcChar])
return genPwd
if __name__ == '__main__':
print (GenPassword(6))
