Basic Prometheus exporter for Patroni.
Currently only supports Consul as a DCS but extending would be reasonably trivial. It currently serves my use case monitoring Patroni running on Hashicorp Nomad where Consul service registration is managed by Nomad. It's untested against Patroni-registered services but it would probably Just Work (tm).
Binaries for Linux and macOS can be found under Releases - grab the latest for your platform there.
