Ask HN: What is your monitoring stack on AWS?

I am looking for a monitoring solution that is web scale in terms of pricing (we have 100.000 req/min website).

Most of the enterprise solutions cost the same amount of money as running the entire infrastrcuture serving the website. I am not sure if this is acceptable.

I was wondering if there is anything out there that has support for the following:

- application performance monitoring (.NET)

- host metrics (EC2 / ECS)

- custom metrics

- application logs

- aplication traces

- core web vitals

- mobile app metrics

- mobile crash report

- frontend monitoring (how long do the backend API calls take)

It appears to me that enterprise tools cover these areas very well for a significant cost. I was wondering if there are tools that use something like S3 and ECS for storage and querying respectively.
