I made a proof of concept using Docker Compose showing dynamic debug logging in the cloud using a structured logging framework. The PoC uses script and JSONPath to evaluate the input structured data to determine criteria for logging:

I have examples of more dynamic logging stuff:

There's a couple of other instance of dynamic logging, but it does not seem to be very well known. For example the Linux kernel:

and Pixie, using Go and eBPF:

I've been working on logging for a while and I've released and open sourced a new Java logging API I'm really happy with.

Echopraxia [1] is a Java logging API like SLF4J, but built around structured logging, i.e. the basic log entry is a JSON object and log files are typically NDJSON. It also has conditions, context, and also has semantic and fluent logging options.

Here's a Spring Boot Example [2].

And here's my blog post [3].
