}

Set tracing and metrics

package main

import(
	"gorm.io/plugin/opentelemetry/tracing"
)

func init(){

	db, err := gorm.Open(sqlite.Open("file::memory:?cache=shared"), &gorm.Config{})
	if err != nil {

	if err := db.Use(tracing.NewPlugin()); err != nil {
		panic(err)
	}
}

Set only tracing

package main

import(
	"gorm.io/plugin/opentelemetry/tracing"
)

func init(){

	db, err := gorm.Open(sqlite.Open("file::memory:?cache=shared"), &gorm.Config{})
	if err != nil {
		panic(err)
	}

	if err := db.Use(tracing.NewPlugin(tracing.WithoutMetrics())); err != nil {
		panic(err)
	}
}
