[背景]本文的宗旨，是为解决在后期Nagios添加监控对象而烦的管理员做的工具。当然，也是为我减轻工作，而开发的。虽然说，我们可以写脚本来解决，但如果是那种每天会添加一两个IP来做监控，那么我们是不是每天都要登录服务器，修改配置文件，再测试，重启。感觉不是很方便，如果有一个web界面来操作，那视觉肯定又不一样，与是我就想到了要开发这款工具，来为自己或者大家来解决现在的问题，可能会有人说，现在的这样的图形工具太多了，是的，我也测试了一款，但感觉不是很理想，把我原先的配置文件全打乱了，而且在添加监控对象的时候，N多参数要填写，那个烦啊!~今天，这款工具，只要平台支持php，基本就可以使用了。喜不喜欢，在与能不能让你的工作更方便，不过，我已经准备用它了。呼呼....

附上一款备份nagios配置文件的脚本
#!/usr/bin/env python
'''Backup config files of nagios'''
import glob
import os
import time
import shutil
nagios_path="config file of nagios"
bak_path="/backup/nagios/"
DATEFORMAT="%Y%m%d"
class nagios(object):
pass
def copy():
cp_nagios = nagios()
os.chdir(nagios_path)
filelist=glob.glob('*.cfg')
datedir=time.strftime(DATEFORMAT,time.localtime())
dirname=bak_path+datedir
if not os.path.exists(dirname):
os.mkdir(dirname)
for file in filelist:
sfile=nagios_path+file
shutil.copy(sfile,dirname)
if __name__ == '__main__':
copy()
