class PING(Thread):

def __init__(self,ip):

Thread.__init__(self)

self.ip=ip

def run(self):

Curtime = datetime.datetime.now()

#Scrtime = Curtime + datetime.timedelta(0,minute,0)

#print("[%s]主机[%s]" % (Curtime,self.ip))

ping=pexpect.spawn("ping -c1 %s" % (self.ip))

check=ping.expect([pexpect.TIMEOUT,"1 packets transmitted, 1 received, 0% packet loss"],2)

if check == 0:

print("[%s] 超时 %s" % (Curtime,self.ip))

elif check == 1:

print ("[%s] %s 可达" % (Curtime,self.ip))

else:

print("[%s] 主机%s 不可达" % (Curtime,self.ip))

#多线程同时执行

T_thread=[]

for i in host:

t=PING(i)

T_thread.append(t)

for i in range(len(T_thread)):

T_thread[i].start()

#

#print ("n=========问题主机情况如下==========n")

#output(report_error)

#print ("n=========正常主机情况如下==========n")

#output(report_ok)

执行结果：

administrator@nagios:/win/pexpect$ ./ping.py
