默认配置文件
windows:在用户文件夹下 C:\Users\Administrator.influxdbv2 linux: /etc/influxdb/influxdb.conf
二、C#调用
Load DataSources 选择c# 查看配置示例 创建一个控制台程序
安装InfluxDB客户端
创建链接
using System.Linq;
using System.Threading.Tasks;
using InfluxDB.Client;
using InfluxDB.Client.Api.Domain;
using InfluxDB.Client.Core;
using InfluxDB.Client.Writes;namespace Examples
{public class Examples{public static async Task Main(string[] args){// You can generate an API token from the API Tokens Tab in the UIvar token Environment.GetEnvironmentVariable(INFLUX_TOKEN)!;const string bucket Test;const string org CC;using var client new InfluxDBClient(http://127.0.0.1:8086, token);}}
}写入数据 //方式一、使用WriteRecord
const string data mem,hosthost1 used_percent23.43234543;
using (var writeApi client.GetWriteApi())
{writeApi.WriteRecord(data,bucket, org, WritePrecision.Ns );
}//方式二、使用WritePoint
var point PointData.Measurement(mem).Tag(host, host1).Field(used_percent, 23.43234543).Timestamp(DateTime.UtcNow, WritePrecision.Ns);using (var writeApi client.GetWriteApi())
{writeApi.WritePoint(point,bucket, org);
}//方式三、使用实体类
var mem new Mem { Host host1, UsedPercent 23.43234543, Time DateTime.UtcNow };using (var writeApi client.GetWriteApi())
{writeApi.WriteMeasurement( mem,bucket, org, WritePrecision.Ns);
}[Measurement(mem)]
private class Mem
{[Column(host, IsTag true)] public string Host { get; set; }[Column(used_percent)] public double? UsedPercent { get; set; }[Column(IsTimestamp true)] public DateTime Time { get; set; }
}最终测试代码
// See https://aka.ms/new-console-template for more information
using InfluxDB.Client;
using InfluxDB.Client.Api.Domain;
using InfluxDB.Client.Writes;Console.WriteLine(Hello, World!);
Environment.SetEnvironmentVariable(INFLUX_TOKEN, O9I2Kpeg...kLPSrQLWhTiJCQPWy6HJFjN9hK33UoLnG34vfFdqZ5KmoDLS-kkw);var token Environment.GetEnvironmentVariable(INFLUX_TOKEN)!;
const string bucket Test;
const string org CC;using (var client new InfluxDBClient(http://localhost, token))
{using (var writeApi client.GetWriteApi()){while (true){var randon new Random();var point PointData.Measurement(mem).Tag(host, host1).Field(used_percent, randon.Next(10, 100)) //可以添加多个字段.Field(memory_percent,randon.Next(0,10)).Timestamp(DateTime.UtcNow, WritePrecision.Ns);writeApi.WritePoint(point, bucket, org);Thread.Sleep(2000);}}
