Expected answer

I use "db.Callback().Query().After(" gorm:after_query ").Register(" after_query ", errCircult)" to register errCircult to detect db circult status. how can I get addr(ip adn port) from a gorm.DB value.
func errCircult(db *gorm.DB) {
if db.Error!= nil && db.Error!= gorm.ErrRecordNotFound {
ins, _:= MysqlPolarisApi.GetInstance(map[string]string{ "ro": "sz" })
// how to get ip and report it to Circuit Breaker
MysqlPolarisApi.CallResult(ins, model.RetFail, 1002, time.Duration(100))
}
}
