@Injectable()
export class TrafficService {
    constructor(private readonly influx_service: InfluxDbService) {}

    public async getLastDay(): Promise<ResponseDto> {
        const results = await this.influx_service.query(`
            select MEAN(*) from traffic WHERE time > now() - 1d GROUP BY time(10m);
        `);

        return results.map(pointToDto);
    }
}
