It's been quite a few years, but when I started in telco, we had a vendor product that I think sort of worked like this. They were using a "micro-services" architecture within their nodes before it became popular. They also used a crash-only approach to writing software. So lots of asserts for unhandled / unexpected cases.

As I remember it, they wrote their crash handler to include the ring buffer of recent messages sent to the services. So whenever they'd get into an unexpected state, they'd just crash the process, and collect the ring buffer of recent messages along with the other normal things in a mini core. Made it so easy to track down those unexpected / corner cases in that platform.
