Note

The article is being updated.

Below are examples of the code for enabling metrics in Prometheus in different YDB SDKs

Go

package main
import (
    "context"
    "github.com/prometheus/client_golang/prometheus"
    metrics "github.com/ydb-platform/ydb-go-sdk-prometheus"
    "github.com/ydb-platform/ydb-go-sdk/v3"
    "github.com/ydb-platform/ydb-go-sdk/v3/trace"
)
func main() {
    ctx := context.Background()
    registry := prometheus.NewRegistry()
    db, err := ydb.Open(
        ctx,
        os.Getenv("YDB_CONNECTION_STRING"),
        metrics.WithTraces(
            registry,
            metrics.WithDetails(trace.DetailsAll),
            metrics.WithSeparator("_"),
        ),
    )
    if err != nil {
        panic(err)
    }
    defer func() {
        _ = db.Close(ctx)
    }()
}
