multiple goroutines panic #1172

Open huyujie opened 2 years ago

huyujie commented 2 years ago 
import (
proclientApi "github.com/prometheus/client_golang/api"
)

var ProClientMap = make(map[string]proclientApi.Client, 0)

func PromQueryRange(){
    ProClient := proclientV1.NewAPI(ProClientMap[dataSource])
    value, _, err := ProClient.QueryRange(ctx, sql, r)
    if err != nil {
         logger.Errorf("[proQuery]error,[%v]", err)
         return PromMonitorData, err
    }
}

when concurrent PromQueryRange,ProClient.QueryRange panic,why?

Did you read the docs?

NewAPI returns a new API for the client.

It is safe to use the returned API from multiple goroutines.

cf. https://pkg.go.dev/github.com/prometheus/client_golang@v1.14.0/api/prometheus/v1#NewAPI
