设计思路：
- 统计job 基础信息，记录为max_mem.log
- 统计job reserved信息，记录为reserved.log
- 合并上面两个信息，记录为merge.log
- 计算筛选出差值的2倍job
- 对结果进行排序方便查看
输出结果展示：
步骤一，设计运行脚本：

/home/chenrui/reserved_zabbix/reserved.sh > /home/chenrui/reserved_zabbix/reserved.log
#合并信息，记录为merge.log
/home/chenrui/reserved_zabbix/merge.sh > /home/chenrui/reserved_zabbix/merge.log
#计算筛选出差值2倍的job
/home/chenrui/reserved_zabbix/account.sh > /home/chenrui/reserved_zabbix/account.log

步骤二，设置定时任务，略
步骤三，zabbix配置，略
