I simply doubt that most of these logs (or anyone’s, usually) are that useful.

I worked at a SaaS observability company (Datadog competitor) that was ingesting, IIRC, multiple GBps of metrics, spread across multiple regions, dozens upon dozens of cells, etc. Our log budget was 650 GB/day.

I have seen – entirely too many times – DEBUG logs running in prod endlessly, messages that are clearly INFO at best classified as ERROR, etc. Not to mention where a 3rd party library is spamming the same line continuously, and no one bothers to track down why and stop it.
