• Druid 基础使用-操作篇(Imply )


    一、Imply

        Druid 原生的配置较麻烦,在上一篇单机版安装中有所涉及
       Imply 基于Druid 进行了一些组件的开发,提供开源社区版本和商业版,简化了部署,开发了一些应用.https://imply.io/product

    二、

    安装

    1. 下载nodejs 安装(http://jingyan.baidu.com/article/dca1fa6f48f478f1a5405272.html)
    2. .安装imply
      1. 下载最新版本 imply-1.3.1.tar  https://imply.io/download
      2. tar -xzf imply-1.3.1.tar
    3. 启动
       1[root@Druid imply-1.3.1]# bin/supervise -c conf/supervise/quickstart.conf  -可以nohup 后台执行

    三、Imply 数据的发送
            1.修改 tranquility 组件下server.josn 中的数据相关信息 --表名称、维度列、指标列
             修改后的数据结构如下
             

    {
        "dataSources": {
            "pageviews": {
                "spec": {
                    "dataSchema": {
                        "dataSource": "pageviews",
                        "parser": {
                            "type": "string",
                            "parseSpec": {
                                "timestampSpec": {
                                    "format": "auto",
                                    "column": "time"
                                },
                                "dimensionsSpec": {
                                    "dimensions": [
                                        "url",
                                        "user"
                                    ]
                                },
                                "format": "json"
                            }
                        },
                        "granularitySpec": {

                        },
                        "metricsSpec": [
                            {
                                "name": "views",
                                "type": "count"
                            },
                            {
                                "name": "latencyMs",
                                "type": "doubleSum",
                                "fieldName": "latencyMs"
                            }
                        ]
                    },
                    "ioConfig": {
                        "type": "realtime"
                    },
                    "tuningConfig": {
                        "type": "realtime",
                        "maxRowsInMemory": "100000",

            2.重新启动Imply --这个地方有个疑问  如何动态的设置表的名称呢?tranquility 重启 原因在于重启的时候指定了server.json 这个配置文件?

          3.在linnux系统中进行数据的发送
                    curl -XPOST -H'Content-Type: application/json' --data-binary @../003.jsonhttp://*。*。*。*:8200/v1/post/pageviews  --pageviews 必须提前声明,否则回提示数据源未定义 ,如何动态增加呢

               003.josn 数据源的数据,一定要注意time 数据,一是时间最好是当前时间,否则tranquility 仅能收到数据,不会想Druid进行数据的发送,比如  receive 3 send 0

              

            如果一切正常,将会受到 received 3 send 3

       4.c# 代码进行json数据的发送 --post json 
           

     1 /// <summary>
     2         /// 插入数据,基于服务端已经有的一个表pageviews
     3         /// </summary>
     4         [TestMethod]
     5         public void InsertData()
     6         {
     7             string url = "http://*.*.*.*:8200/v1/post/pageviews"; //发送数据
     8             string data = PostHttp(url, GetData());
     9             DruiExecuteResult result = JsonConvert.DeserializeObject<DruiExecuteResult>(data);
    10 
    11             Assert.IsTrue(result.result.received == "100");
    12             Assert.IsTrue(result.result.received == "100");
    13         }
    14          public string GetData()
    15         {
    16             StringBuilder sb = new StringBuilder();
    17             string temp = string.Empty;
    18             string ISO8601time = string.Empty;

    22                 temp = "{"time":"" + ISO8601time + "","url":"test" + i.ToString() + "","user":"hello" + i.ToString() + "","latencyMs":" + i.ToString() + "}";
    23                 sb.AppendLine(temp);
    24             }
    25 
    26             string result = sb.ToString();
    27 
    28             return result;
