AWS load balancer log analyzer

Question

I'm new to AWS wolrd. My purpose is to find as soon as possible in case of problems using Elastic Load Balancer logs top ips from requests, if possible who they are or some inspection on it. I only found paid services. Does anyone know a free application or maybe a website that analyzes AWS ELB logs?

Answer 1

Completely free solution isn't available as I know. Btw, there are cheap solutions.

You can monitor your load balancer by "Access logs", "CloudWatch metrics", "Request tracing" and "CloudTrail logs".

I don't understand exactly what you want, but there are some possible solutions.

• If you're afraid of being attacked and you need immediate protection (against security scans, DDoS etc), you can use AWS's own services. "AWS Shield Standard" is automatically included at no extra cost. Btw, "For added protection against DDoS attacks, AWS offers AWS Shield Advanced". https://docs.aws.amazon.com/shield/
• WAF is also good against attacks. You can create rules, rule-actions etc. Sadly it's not completely free. It runs "pay-as-you-use" style. https://aws.amazon.com/waf/pricing/
• you can store the access log in S3 and analyse it later, but this can be costly in the end (and it's not real time)
• you can analyse your log records with Lambda function. In this case, you need to use some NoSQL or something to store states or logics. (Lambda and DynamoDB is "pay-as-you-use" style and cheap, but not for free)

Keep in mind that:

• The load balancer and lambda also increments the corresponding CloudWatch metric (it's cheap, but not for free)
• You will pay for the outgoing data transfer. I mean from AWS to internet 1TB/month/account is always free: https://aws.amazon.com/free/
• you should use AWS's own services if you want a cheap and good solution
