psutil  模块   2018/9/23
import psutil
---------------------------------------------------------------------------------------------
1.1.描述
psutil是一个用于检索信息的跨平台库
运行进程和系统利用率(CPU,内存,磁盘,网络,传感器)在Python中。
1.2.模块内容psutil.Processpsutil.test()psutil.Popenpsutil.AccessDenied
ZombieProcess类(NoSuchProcess)
---------------------------------------------------------------------------------------------
2.class Popen(Process)用途：# stdlib subprocess.Popen类的更方便的接口。# 它启动一个子流程并完全像使用时一样处理它subprocess.Popen类,提供了所有psutil.Process类的属性和方法说明：# 与subprocess.Popen不同,此类先发制人地检查是否为PID已经在send_signal(),terminate()和kill()上重用了这个# 你不会意外地终止另一个进程,修复http://bugs.python.org/issue6973。# # 有关完整文档,请参阅：# http://docs.python.org/library/subprocess.html方法:wait(self, timeout=None)# 等待进程终止, 如果进程是子进程os.getpid(), 也返回其退出代码, 否则为None。# 要等待多个进程, 请使用psutil.wait_procs()。实例：import psutilfrom subprocess import PIPEp = psutil.Popen(["python", "-c", "print( 'hi')"], stdout=PIPE)a=p.name()print(a)# 'python'# a1=psutil.Process.uids# print(a)# user(real=1000, effective=1000, saved=1000)a=p.username()print(a)# 'giampaolo'a=p.communicate()print(p.communicate())# ('hi', None)p.terminate()p.wait(timeout=2)-------------------------------------------------- ------------------------------
3.class Process
class  Process(pid=None) 表示具有给定PID的OS进程。参数：# 如果省略PID,则使用当前进程PID(os.getpid())# 如果PID不存在,则提升NoSuchProcess。# 注意#     进程标识的唯一例外是先发制人检查和保证是：#     - parent()#     - children()#     - nice() (set)#     - ionice() (set)#     - rlimit() (set)#     - cpu_affinity (set)#     - suspend()暂停#     - resume()恢复#     - send_signal()#     - terminate()终止#     - kill()## 解决办法：# - 在查询进程之前使用is_running()# - 如果你不断迭代一组进程实例使用进行先发制人检查的process_iter()每个产生的实例的进程标识属性：pid     #process PID.---------------------------------------------------------------------------------
3.2.方法：
as_dict(self,attrs = None,ad_value = None)实用方法返回流程信息可以翻译的字典。# attrs 必须是字符串列表反映可用Process类的属性名称如['cpu_times','name']否则全部公开(读only)假设属性。# ad_value 是在案例中分配的值当引发AccessDenied或ZombieProcess异常时检索特定的流程信息。children(self, recursive=False)将此过程的子项作为Process列表返回实例,先发制人地检查PID是否已被重用。# recursive=True,则返回所有父后代。Example (A == this process):A ─┐│├─ B (child) ─┐│             └─ X (grandchild) ─┐│                                └─ Y (great grandchild)├─ C (child)└─ D (child)>>> p = psutil.Process()>>> p.children()
        # B,C,D>>> p.children(recursive = True)# B,X,Y,C,Dcmdline(self)已调用此进程的命令行。#connections(self, kind='inet')返回由进程打开的套接字连接作为列表# (fd,family,type,laddr,raddr,status)namedtuples。# * kind *参数筛选匹配的连接cpu_affinity(self,cpus = None)获取或设置进程CPU关联。# 如果指定,* cpus *必须是您的CPU列表想要设置亲和力(例如[0,1])。# 如果传递空列表,则假定所有可用的CPU(并设定)。(仅限Windows,Linux和BSD)。#cpu_percent(self,interval = None)返回表示当前进程CPU的浮点数利用率百分比。#cpu_times(self)# 返回a(user,system,children_user,children_system)# 表示累计处理时间的namedtuple秒。这类似于os.times()但是每个进程。# 在macOS和Windows上,children_user和children_system是始终设为0。#create_time(self)进程创建时间为浮点数自UTC以来以秒为单位表示。# 首次调用后会返回返回值。#cwd(self)将当前工作目录作为绝对路径处理。#environ(self)作为dict的进程的环境变量。#exe(self)该进程可作为绝对路径执行。# 也可能是一个空字符串。首次调用后会返回返回值。#io_counters(self)返回进程I / O统计信息# 为(read_count,write_count,read_bytes,write_bytes)namedtuple。# 这些是执行的读/写调用次数和进程读取和写入的字节数。#ionice(self,ioclass = None,value = None)获取或设置进程I / O良好性(优先级)。# 在Linux *上,ioclass *是IOPRIO_CLASS_ *常量之一。# * value *是一个从0到7的数字value,进程的I / O优先级越低。# 在Windows上仅使用* ioclass *,它可以设置为2(正常),1(低)或0(非常低)。仅适用于Vista。#is_running(self)返回此进程是否正在运行。# 它还检查PID是否已被其他进程重用哪个案例返回False。#memory_full_info(self)此方法返回与memory_info()相同的信息#memory_info(self)返回一个带有可变字段的namedtuple,取决于平台,表示有关进程的内存信息。
#memory_maps(self,grouped = True) 返回进程'将内存区域映射为namedtuples列表# 其字段可变,具体取决于平台。memory_percent(self,memtype ='rss')将进程内存与总物理系统内存进行比较# 以百分比计算进程内存利用率。# * memtype *参数是一个字符串,指示什么类型的要比较的进程内存(默认为“rss”)。# 可以像这样获得可用字符串列表：>>> psutil.Process().memory_info()._fields# ('rss','vms','shared','text','lib','data','dirty','uss','pss')name(self)进程名称。首次调用后会返回返回值。nice(self, value=None)获取或设置进程的好处(优先级)。num_ctx_switches(self)返回自愿和非自愿背景的数量由此过程执行的开关。num_handles(self)返回此进程打开的句柄数(仅限Windows)。num_threads(self)返回此进程使用的线程数。oneshot(self)实用程序上下文管理器,大大加快了同时检索多个过程信息。>>> p = psutil.Process()>>> with p.oneshot()：... p.name()＃收集多个信息... p.cpu_times()＃返回缓存值... p.cpu_percent()＃返回缓存值... p.create_time()＃返回缓存值open_files(self)将进程打开的文件作为列表返回# (path,fd)namedtuples包括绝对文件名和文件描述符号。 parent(self)先发制人地将父进程作为Process对象返回检查PID是否已被重用。# 如果没有父母知道,则返回None。ppid(self)进程父PID。在Windows上,首次调用后会返回返回值。resume(self)使用SIGCONT进行先发制人检查以恢复流程执行PID是否已被重用。# 在Windows上,这具有恢复所有进程线程的效果。send_signal(self,sig)发送信号* sig *以进行先发制人检查# PID是否已被重用(参见信号模块常量)。在Windows上,只有SIGTERM有效并被视为别名status(self)过程当前状态为STATUS_ *常量。suspend(self)使用SIGSTOP暂停检查暂停流程执行PID是否已被重用。# 在Windows上,这具有暂停所有进程线程的效果。terminate(self)使用SIGTERM进行先发制人检查以终止该过程# PID是否已被重用。在Windows上,这是kill()的别名。threads(self)返回由进程打开的线程作为列表# (id,user_time,system_time)namedtuples表示线程ID和线程CPU时间(用户/系统)。username(self)拥有该进程的用户的名称。wait(self, timeout=None)等待进程终止,如果进程是子进程os.getpid(),也返回其退出代码,否则为None。# 如果进程已经终止,则立即返回None而不是提高NoSuchProcess。# 如果指定了* timeout *(以秒为单位)并且进程仍然存在live raise TimeoutExpired。# 要等待多个进程,请使用psutil.wait_procs()。--------------------------------------------------------- --------------------
ZombieProcess(pid,name = None,ppid = None,msg = None)查询僵尸进程时出现异常。# 这是仅在macOS,BSD和Solaris上提出,并不总是：依赖在查询上,OS无论如何都可能成功。# 在Linux上,所有僵尸进程都是可以使用的(因此这绝不是上调)。 Windows没有僵尸进程。
