前提 前提
我们使用自动发现功能是为了节省新增监控项、触发器的时间，zabbix自动识别会新增哪些监控项，常用语，cpu，每个cpu的利用率。文件系统，每个挂载目录的使用情况等。
现在有一个监控项，通过脚本获取到线路的track的状态，要对获取的数据进行监控项展示，json数据如下。
[ { "naq_entry":"线路名称", "trackid":"1", "State":"Positive", "Local IP":"2.2.2.2" }, { "naq_entry":"线路名称", "trackid":"2", "State":"Positive", "Local IP":"2.2.2.2" }, { "naq_entry":"线路名称", "trackid":"3", "State":"Positive", "Local IP":"2.2.2.2" }, { "naq_entry":"线路名称", "trackid":"4", "State":"Positive", "Local IP":"2.2.2.2" }, { "naq_entry":"线路名称", "trackid":"5", "State":"Positive", "Local IP":"2.2.2.2" }, { "naq_entry":"线路名称", "trackid":"6", "State":"Positive", "Local IP":"2.2.2.2" }, { "naq_entry":"线路名称", "trackid":"7", "State":"Positive", "Local IP":"2.2.2.2" }, { "naq_entry":"线路名称", "trackid":"8", "State":"Positive", "Local IP":"2.2.2.2" }, { "naq_entry":"线路名称", "trackid":"9", "State":"Positive", "Local IP":"2.2.2.2" }, { "naq_entry":"线路名称", "trackid":"10", "State":"Positive", "Local IP":"2.2.2.2" }, { "naq_entry":"线路名称", "trackid":"11", "State":"Positive", "Local IP":"2.2.2.2" }, { "naq_entry":"线路名称", "trackid":"12", "State":"Positive", "Local IP":"2.2.2.2" }, { "naq_entry":"线路名称", "trackid":"13", "State":"Positive", "Local IP":"2.2.2.2" }, { "naq_entry":"线路名称", "trackid":"15", "State":"Positive", "Local IP":"2.2.2.2" }, { "naq_entry":"线路名称", "trackid":"16", "State":"Positive", "Local IP":"2.2.2.2" }, { "naq_entry":"线路名称", "trackid":"17", "State":"Positive", "Local IP":"2.2.2.2" }, { "naq_entry":"线路名称", "trackid":"18", "State":"Positive", "Local IP":"2.2.2.2" }, { "naq_entry":"线路名称", "trackid":"19", "State":"Positive", "Local IP":"2.2.2.2" }, { "naq_entry":"线路名称", "trackid":"20", "State":"Positive", "Local IP":"2.2.2.2" }]
一、在监控项上，“创建自动发现规则”
二、“键值"随便写一个不重复的
三、定义"LLD macros”，把json的监控项变成宏名称，被下一步监控项模型引用
四、新建监控项模型，"键值"项，必须不能一直，所以加了一个名称[宏名称]
五、监控项模型中，根据JSONPath获得数据，当TRACKID匹配到1时，自动获取TRACKID=1的json中名称
$[?(@.trackid==’{#TRACKID}’)].naq_entry.first()
六、保存后即可等待监控项的采集后，自动发现即根据监控项模型，生成监控项。
七、触发器配置（未开始）。
