Are you joking or is there actually a datadog-like startup named dev null?
I'm saying most logs are pointless to keep and would be better directed to /dev/null. Keep important transaction related logs and sample the rest. The notion that every single log or metric across your entire technical architecture is worth keeping is one implanted by SaaS providers with a financial interest in naive engineers doing just that.
We have concepts of debug, info, warn and error… but I think we need apps to be developed with the concept of log concern.
For example take sshd. For infosec they are interested in IP of failed attempts, operations might want to know connection failures, etc.
