Favorite AWS Athena queries for ALB Logs stored in S3


What is the most visited page by the client and total traffic on my website?

SELECT sum(received_bytes) as total_received, sum(sent_bytes) as total_sent, client_ip, 
count(client_ip) as client_requests, request_url  
FROM alb_logs 
GROUP BY client_ip, request_url  
ORDER BY total_sent  desc;

How long does it take to process requests on average?

SELECT sum(request_processing_time) as request_pt, sum(target_processing_time) as target_pt,
sum (response_processing_time) respone_pt, 
sum(request_processing_time + target_processing_time + response_processing_time) as total_pt, 
count(request_processing_time) as total_requests,
sum(request_processing_time + target_processing_time + response_processing_time) / count(request_processing_time) as avg_pt,
request_url, target_ip
FROM alb_logs WHERE target_ip <> ''
GROUP BY request_url, target_ip 
HAVING COUNT (request_processing_time) > 4 
ORDER BY avg_pt desc;

Which requests does the site doesn’t process?

It’s usually some person trying to find some vulnerable PHP code.

SELECT count(client_ip) as client_requests, client_ip, target_ip, request_url, 
target_status_code 
FROM alb_logs 
WHERE target_status_code not in ('200','301','302','304') 
GROUP BY client_ip, target_ip, request_url, target_status_code
ORDER BY client_requests desc;
