summary

Describes porting a Prometheus exporter into Unikraft by adding it as a library running on a separate thread and using a ukstore intermediary (ProcFS-like) to expose metrics. Covers how ukstore provides build-time static and run-time dynamic entries for libraries to publish memory, networking and thread-locking metrics (with filesystem/CPU in progress), and how a low-dependency exporter was patched to collect those metrics with minimal performance impact.
