I like podman, but is there any progress with monitoring solutions? cAdvisor image didn't work last I checked. What I need is a way for data to flow into prometheus.

Podman does support docker API so you can use something like the OpenTelemetry Collector to fetch metrics using the docker API and forward them to prometheus.

Collector: https://github.com/open-telemetry/opentelemetry-collector-co...

Docker receiver: https://github.com/open-telemetry/opentelemetry-collector-co...

Prometheus exporters: https://github.com/open-telemetry/opentelemetry-collector-co... and https://github.com/open-telemetry/opentelemetry-collector-co...

OpenTelemetry will soon support native Podman API as well.
