Influxdb2 sources add data sources

It is mainly divided into the following ways ：

1、 Upload files

2、 client API： This tutorial mainly adds data in this way

3、telegraf plug-in unit , Telegraph plug-in

With C# Take the client as an example ：

 

Choose to generate API token：

 

 

Then return to this interface ：

 

  establish vs2019 Console Application ：

 

Actual test findings /netframework4.5 Cannot install this nuget package ：

Adjusted for 4.7.2 after .

C# The code is as follows ：

// You can generate an API token from the "API Tokens Tab" in the UI
            const string token = "oskR6XS-LT5myc6RwWwb0QTvKSsoWvfxklNXgkknYgzZJyk0K80IKhFQuMSGexfjCSRCO-xUHA0MFL0LG5BlFA==";
            const string bucket = "scada_bucket";
            const string org = "ghy";

            //  Get client object 
            var client = InfluxDBClientFactory.Create("http://124.223.23.44:8086", token);

            //  Writing data 
            const string data = "mem,host=host1 used_percent=23.43234543";
            using (var writeApi = client.GetWriteApi())
            {
                writeApi.WriteRecord(bucket, org, WritePrecision.Ns, data);
            }
            Console.WriteLine("ok");

  Write successfully ：

  Use node-red Client to test ：

Install nodes ：node-red-contrib-influxdb

contain 3 Nodes ：

 

Write operations ：

 

 

 

 

  The information above is wrong ：

Set node information ：

 

 

The overall process is as follows ：

 

Test whether the write is successful :

Use the output node to view ：

The overall process is as follows ：

 

The timestamp node remains the default .

The configuration of the setting node is as follows :

The query statement is as follows ：

from(bucket: \"scada_bucket\") |> range(start: -1h)

  The output node is configured as follows ;

Passing the above test has no result ：

Report errors ：

 

Be careful ： The query function has not passed the test for the time being , But the data is really inserted .
