Go
Use Go Client write data.
Installation
- Go 1.18 or later is required;
- Add the client package to your project dependencies (
go.mod);go get github.com/lindb/client_go - Add
import github.com/lindb/client_goto your source code;

package main
import (
"context"
"fmt"
"time"
lindb "github.com/lindb/client_go"
"github.com/lindb/client_go/api"
)
func main() {
// create write client with options
cli := lindb.NewClientWithOptions(
"http://localhost:9000",
lindb.DefaultOptions().SetBatchSize(200).
SetReqTimeout(60).
SetRetryBufferLimit(100).
SetMaxRetries(3),
)
// get write client
w := cli.Write("_internal")
// get error chan
errCh := w.Errors()
go func() {
for err := range errCh {
fmt.Printf("got err:%s\n", err)
}
}()
// write some metric data
for i := 0; i < 10; i++ {
// write cpu data
w.AddPoint(context.TODO(), api.NewPoint("cpu").
AddTag("host", "host1").
AddField(api.NewSum("load", 10.0)).
AddField(api.NewLast("usage", 24.0)))
// write memory data
w.AddPoint(context.TODO(), api.NewPoint("memory").
AddTag("host", "host1").
AddField(api.NewLast("used", 10.0)).
AddField(api.NewLast("total", 24.0)))
}
// close write client
w.Close()
}
