OpenTSDB 简单使用 .NET

OpenTSDB是基于Hbase的时序数据库[时间序列数据库]。不具备通用性，主要针对具有时间特性和需求的数据，如监控数据、温度变化数据等。

1、安装OpenTSDB

安装前一定要安装HBase，相关的安装方式在网上有很多了。下载地址：https://github.com/OpenTSDB/opentsdb/releases

2、设置OpenTSDB

创建metric：两种方式，选择其一即可。

在opentsdb中创建metric。如生成 bridge 如下： tsdb mkmetric bridge
修改opentsdb.conf设置： tsd.core.auto_create_metrics = true

3、C# 数据上传

Nuget Install-Package RestSharp -Version 106.6.10

   public class DataPoint
    {
        public string metric { get; set; }
        public int timestamp { get; set; }
        public int value { get; set; }
        public Tags tags { get; set; }
    }

    public class Tags
    {
        public string host { get; set; }
        public string dc { get; set; }
    }

基础类

  class Program
    {
        static void Main(string[] args)
        {
            List<DataPoint> point = new List<DataPoint>();
            for(int i = 1; i <= 50; i++)
            {
                point.Add(new DataPoint()
                {
                    metric = "bridge",
                    timestamp = ConvertDateTimeInt(DateTime.Now.AddMinutes(i)),
                    value = new Random().Next(1,50),
                    tags = new Tags()
                    {
                        host = "YL-01-01",
                        dc = "BL"
                    }
                });
            }

            var client = new RestClient("IP地址:4242/api/put?summary=");
            var request = new RestRequest(Method.POST);
            request.AddHeader("cache-control", "no-cache");
            request.AddHeader("Connection", "keep-alive");
            request.AddHeader("Content-Length", "235");
            request.AddHeader("Accept-Encoding", "gzip, deflate");
            request.AddHeader("Content-Type", "application/json");
            request.AddParameter("undefined", JsonConvert.SerializeObject(point), ParameterType.RequestBody);
            IRestResponse response = client.Execute(request);
            Console.WriteLine(response.Content);

            Console.ReadKey();
        }
        public static int ConvertDateTimeInt(System.DateTime time)
        {
            System.DateTime startTime = TimeZone.CurrentTimeZone.ToLocalTime(new System.DateTime(1970, 1, 1));
            return (int)(time - startTime).TotalSeconds;
        }
    }
