)

db, err := gorm.Open(sqlite.Open("gorm.db"), &gorm.Config{})

    fmt.Errorf("error opening database: %v", err)
}

db.Use(prometheus.New(prometheus.Config{
    DBName:          "db1",                       // `DBName` as metrics label
    RefreshInterval: 15,                          // refresh metrics interval (default 15 seconds)
    PushAddr:        "prometheus pusher address", // push metrics if `PushAddr` configured
    StartServer:     true,                        // start http server to expose metrics
    HTTPServerPort:  8080,                        // configure http server port, default port 8080 (if you have configured multiple instances, only the first `HTTPServerPort` will be used to start server)
    MetricsCollector: []prometheus.MetricsCollector{
        &prometheus.MySQL{VariableNames: []string{"Threads_running"}},
    },
    Labels: map[string]string{
        "instance": "127.0.0.1",                  // config custom labels if necessary
