利用 PHP 调用 zabbix api 接口, 查询主机, 并返回下面 JSON 数据
内存可用值 (KB)内存总数 (KB)当前 CPU IDLE 值 100%当前 / 盘使用值 (KB)当前 / 盘总数 (KB)
http://zabbix.xxxx.com/ext/get_resource.php?host=hostname,hostname,hostname
可以输入一台或以上主机进行查询, 以逗号进行主机名分隔
可能会出现三种情况
1 主机已在 ZABBIX 注册, 并返回正常的数据2 主机已经在 ZABBIX 注册, 但 ZABBIX AGENT 没有打开, 无法获得当前值3. 主机可能是 WINDOWS 或者没有在 ZABBIX 中注册, 无法获得任何数据
测试返回说明
