GORM provides Prometheus plugin to collect DBStats or user-defined metrics
https://github.com/go-gorm/prometheus
Usage
import (
"gorm.io/gorm"
"gorm.io/driver/sqlite"
"gorm.io/plugin/prometheus"
)
db, err := gorm.Open(sqlite.Open("gorm.db"), &gorm.Config{})
db.Use(prometheus.New(prometheus.Config{
DBName: "db1",
RefreshInterval: 15,
PushAddr: "prometheus pusher address",
StartServer: true,
HTTPServerPort: 8080,
MetricsCollector: []prometheus.MetricsCollector {
&prometheus.MySQL{
VariableNames: []string{"Threads_running"},
},
},
}))User-Defined Metrics
You can define your metrics and collect them with GORM Prometheus plugin, which needs to implements MetricsCollector interface
type MetricsCollector interface {
Metrics(*Prometheus) []prometheus.Collector
}MySQL
GORM provides an example for how to collect MySQL Status as metrics, check it out prometheus.MySQL
&prometheus.MySQL{
Prefix: "gorm_status_",
