从 Nagios 插件解析 Json 输出

Question

我已经搜索了这个网站并尽可能多地用谷歌搜索，但似乎找不到有效的解决方案。

我在家中运行 Nagios 核心，用于监控项目。使用我安装的插件将 status.dat 转换为 Web 服务器上的 Json 文件。

此插件的输出如下所示：

      "percent_state_change": "5.99",
      "scheduled_downtime_depth": "0"
   }
  },

并与主机信息一起永远持续下去。

现在我设法很容易地使用rainmeter web 解析器和一个名为rainregex 的正则表达式助手来解析它。

我想做的是在网页上使用这些信息。

我试过做 jquery：

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"> </script>

<script>
$.getJSON("http://<serverIP>/nagios/statusJson.php", function( data){ 
 var items = [];
$.each( data, function( key, val ) {
items.push( "<li id='" + key + "'>" + val + "</li>" );
});

 $( "<ul/>", {
"class": "my-new-list",
html: items.join( "" )
}).appendTo( "body" );
});
</script>

        </script>

但我无法从 php 文件中提取信息。

我不确定我在这里做错了什么。

Answer 1

如果您仍然对解决方案感到好奇，这可能会对您有所帮助：

1. 如果您从 php 文件中提取，则必须确保回显您创建的 json 编码数组：

回显 json_encode($postData);

1. 您也可以使用 php 跳过解析，直接从 Nagios RESTful API 获取信息（我假设您也安装了 api 插件）。从那里您可以使用您的 jquery 脚本解析和输出 json。

Answer 2

您好，我自己解决了这个问题。

我对 JQuery 不够流利，所以我决定使用 Python 脚本来解析 Json 数据并将其更新为 SQL 表，从这里我可以轻松地使用 PHP 来查询 SQL DB 中的数据。

无论如何，谢谢大家。当我完成脚本润色后，我会尽快编辑此评论。
