Postman Prometheus
Fork: github.com/rubyjedi/postman-prometheus
Upstream: postman-prometheus
The original postman-prometheus tool was useful: run a Postman collection, export the results as Prometheus metrics. One shot, one collection.
What I needed was: run several collections, continuously, all feeding into one /metrics endpoint. The idea being that your Postman collections — which already describe your API contracts — double as live health checks you can scrape with Prometheus and visualize in Grafana.
