如果要獲取每日流量最大值，可以查看zabbix中的graphs，拉取最大值，但是我們還可以從zabbix_api或者數據庫中直接取值，這要靠腳本實現。
有一個需求，收集一部分主機每日進出口流量的最大值，寫了個腳本實現這個功能。
版本一：
根據查找到的主機名，輸入日期後，輸出一日內最大進出口流量
#!/bin/bash
#
###獲取每日流量最大值的腳本，腳本從zabbix數據庫的history_uint表中取
###數據，根據hostname.txt文件中的主機名。

echo -e "\033[32mIP：$host_ip --------> 主機名：$z_hostname\033[0m"
