Use Ping in Python to check network connectivity

Use python to call the ping command and record the ping result in the log to monitor network connectivity.

Code:

from time import *from subprocess import *webf= open("webs.txt","r")webs=[]for w in webf:    webs.append(w.strip())def logAppend(log,info):    inttime = time()    structtime = localtime(inttime)    strtime = strftime("%Y-%m-%d,%H:%M:%S",structtime)    print "at ",strtime    log.write("==================  "+strtime+"  ==================\n")    log.write(info)    log.write("\n\n")    print "append info to file :",log.name    print infodef netCheck():    while True:        for url in webs:            p = Popen(["ping.exe",url],                      stdin=PIPE,stdout=PIPE,stderr=PIPE,                      shell=True)            out = p.stdout.read()            log = open("log\\"+url+".log","a")            logAppend(log,out)            log.close()            sleep(0.01)        print "waiting ..."        sleep(60*15) #sleep for 15min. 60*15    returndef main():    """    the main function    """    print "start..."    netCheck()    print "end."if __name__ == "__main__":    main()

For example, www.baidu.com.

Create a folder named log in the current directory.

About the time module:

Inttime = Time () # the decimal form of the current time is obtained: 1366356992.617 structtime = localtime (inttime) ### convert to local time, # The returned result is: time. struct_time (maid = 2013, tm_mon = 4, tm_mday = 19,

Tm_hour = 15, tm_min = 36, tm_sec = 32, tm_wday = 4, tm_yday = 109, tm_isdst = 0) # This is not pleasing to the eye, continue formatting and conversion: strtime = strftime ("% Y-% m-% d, % H: % m: % s", structtime)

# The returned result is the string in the desired format: 2013-04-19,15: 36: 32

Other parameter types:

Strftime (Format [, tuple])-> string
Returns the specified struct_time (current time by default) according to the specified formatted string.
Time and date formatting symbols in Python:
% Y two-digit year (00-99)
% Y indicates the four-digit year (000-9999)
% M month (01-12)
One day in % d month (0-31)
% H hour in 24-hour format (0-23)
% I 12-hour (01-12)
% M minutes (00 = 59)
% S seconds (00-59)

% A local simplified week name
% A local full week name
% B local simplified month name
% B local full month name
% C local Date and Time
% J one day in the year (001-366)
% P local equivalent of a. m. or P. M.
% U number of weeks in a year (00-53) Sunday is the start of the week
% W Week (0-6), Sunday is the beginning of the week
% W number of weeks in a year (00-53) Monday is the start of the week
% X local date Representation
% X Local Time Representation
% Z Current Time Zone name
% Itself
