zabbix生成资源性能报表+邮件自动发送
使用python调去zabbix数据库groups,hosts_groups,hosts,items,trends,trends_uint表格中的数据组个而成的字典形式，并将其写入excel表格中。其实，核心思想就是用了下面这5个sql语句，获取的数据以字典，列表，元组的格式进行组合，最后形成的返回格式:
{u'10.1.12.33': {'vfs.fs.size[/,total]': '188.65', 'vm.memory.size': '7.69', 'system.swap.size[,total]': '8.00', 'net.if.out': '69.96', 'system.cpu.util[,idle]': '99.72', 'net.if.in': '65.26', 'system.swap.size[,free]': '8.00', 'vfs.fs.size[/,free]': '177.47', 'vm.memory.size': '1.30', 'system.cpu.load': '0.08', 'vm.memory.size': '6.90'}}sql = "select groupid from groups where name='%s'" % groupname
sql = "select hostid from hosts_groups where groupid='%s'" % groupid
sql = "select host from hosts where status=0 and flags=0 and hostid = %s" % hostid
sql = "select itemid from items where hostid='%s' and key_='%s'" % (hostid, itemname)
sql = "select avg(value_%s)/%s result from %s where itemid=%s and clock=%d" % (value, ratio, table, itemid, startime, stoptime)将关注超过阀值的ip的cpu、内存、磁盘单独放在一个sheet中，以邮件的形式定期发送到邮箱。
目前只是实现了各种功能，但是代码还很是粗糙，有些重复冗余的函数，尤其是生成excel和阀值计算这块，后续会继续改进，同时也存在很多bug，一点点找吧
大体思路是抄袭别人的，但是后续在此基础上进行了修改，站在巨人的肩膀上。
zabbix用的是zabbix3.2，同事愿意用新的东西，没办法，就升级了咯，这段代码只提供大体思路，不能保证能在其他环境下运行，这次写的不太成功，移植性太差，看看就行了。
