I write it yesterday to watch the NE process(rcpfd,cfgd) automatically, then i will write a window to implement it:

#! /usr/bin/env python
# -*- coding: UTF-8 -*-

import paramiko
import ssh
import os
import re
import time
#RCPD异常类
class RCPD_Exception(Exception):
def __init__(self,value):
self.value=value
def __str__(self):
return self.value

#CFGD异常类
class CFGD_Exception(Exception):
def __init__(self,value):
self.value=value
def __str__(self):
return self.value

#check进程的函数，进程stuck会报异常，每ss(s>1)秒check一次
def check(hostname,ss):
hostname=hostname
port = 22
username = ‘root‘
password = ‘root‘
#os.chdir(r‘C:\Users\cchen\Desktop‘)
paramiko.util.log_to_file(‘paramiko.log‘)
s = paramiko.SSHClient()
s.load_system_host_keys()
s.set_missing_host_key_policy(paramiko.AutoAddPolicy())
s.connect(hostname,port,username,password)
ssh=s.invoke_shell()
ss-=1
while(1):
time.sleep(ss)
ssh=s.invoke_shell()
ssh.send(‘ps -ef\n‘)
time.sleep(1)
x = ssh.recv(10000)
#print x
pattern1=re.compile(r‘(./rcpd|\[rcpd\])‘)
rcpd=re.findall(pattern1,x)
print rcpd,time.strftime(‘%Y-%m-%d %H:%M:%S‘,time.localtime(time.time()))
pattern2=re.compile(r‘(./cfgd|\[cfgd\])‘)
cfgd=re.findall(pattern2,x)
print cfgd,time.strftime(‘%Y-%m-%d %H:%M:%S‘,time.localtime(time.time()))
if not rcpd[0]==‘./rcpd‘:
try:
raise RCPD_Exception(‘RCPD stuck‘)
except RCPD_Exception,e:
print e

if not cfgd[0]==‘./cfgd‘:
try:
raise CFGD_Exception(‘CFGD stuck‘)
except CFGD_Exception,e:
print e

if __name__==‘__main__‘: check(‘200.200.180.18‘,8)
