class ping(thread):

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
