Laravel7 どのDBに接続しようとしているか（接続されているか）確認する方法

    protected function runQueryCallback($query, $bindings, Closure $callback)
    {
dd($this->pdo);　　←これを追記！！
        // To execute the statement, we'll simply call the callback, which will actually
        // run the SQL against the PDO connection. Then we can calculate the time it
        // took to execute and log the query SQL, bindings and time in our memory.
        try {
            $result = $callback($query, $bindings);
        }

        // If an exception occurs when attempting to run a query, we'll format the error
        // message to include the bindings with SQL, which will make this exception a
        // lot more helpful to the developer instead of just the database's errors.
        catch (Exception $e) {
            throw new QueryException(
                $query, $this->prepareBindings($bindings), $e
            );
        }

        return $result;
    }
