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; } }
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; } }
