【ZABBIX】自动发现实例

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）。
