Python如何监控程序的执行时间并将其写入日志

Python监控程序的执行时间并将其写入日志是如何来实现的呢?下面的内容将会通过具体的实例来演示Python监控程序的执行时间并将其写入日志的实现方法及相关技巧:

本文实例讲述了Python实现监控程序执行时间并将其写入日志的方法。分享给大家供大家参考。具体实现方法如下:

# /usr/bin/python
# -*- coding:utf-8 -*-
from time import time
def logged(when):
  def log(f,*args,**kargs):
    print '''
         called:
          functions:%s
          args: %r
          kargs: %r
    '''  % (f,args,kargs)
  def pre_logged(f):
    def wrapper(*args,**kargs):
      log(f,*args,**kargs)
      return f(*args,**kargs)
    return wrapper
  def post_logged(f):
    def wrapper(*args,**kargs):
      now = time()
      try:
        return f(*args,**kargs)
      finally:
        log(f,*args,**kargs)
        print "time delta:%s" % (time()-now)
    return wrapper
  try:
    return {"pre":pre_logged,"post":post_logged}[when]
  except KeyError,e:
    raise ValueError(e),'must be "pre" or "post"'
@logged("post")
def hello(name):
  print "hello,",name
hello("world!")
'''
等同于: hello = logged("post")(hello("world!"))
'''
 


Python监控程序的执行时间并将其写入日志就是这样,欢迎大家参考。。。。
