我已经找到了想要的答案

SELECT 
    SUM(download_bytes) as download_bytes, 
    SUM(upload_bytes) as upload_bytes, 
    SUM(download_bytes + upload_bytes) as total_bytes, 
    DAY(date) as day, 
    MONTHNAME(date) as month 
FROM 
    traffic_counters 
LEFT JOIN services ON traffic_counters.service_id = services.id 
WHERE 
    date >= (NOW() - INTERVAL 1 MONTH)
GROUP BY 
    MONTH(date),
    DAY(date)
ORDER BY 
    MONTH(date), 
    DAY(date)
