//As a// webservice maintainer
//I want to// expose implementation specific metrics about my tool to Prometheus
//So I can// track and monitor trends and point-in-time issues with my tool.
Today we have general metrics related to each tool's Kubernetes namespace tracked in Prometheus. This feature request imagines augmenting that information with additional application specific metrics under the control of the tool's maintainers. Once collected such metrics can be used to power dashboards and/or alerts via additional configuration in related services.
Prometheus can be configured to examine annotations to find endpoints to scrape. This could be combined with support in `webservice` for adding those annotations to the Deployment to enable collection of custom metrics from a given webservice.
```lang=yaml
annotations:
prometheus.io/scrape: "true"
prometheus.io/path: "/metrics"
prometheus.io/port: "8000"
```
