This repo contains my Prometheus exporter. It allows you to create a multitude of metrics and output them as a simple string that Prometheus can read. It's usage is simple. Create a MetricRegistry, call the appropriate metric methods and set some metrics. It contains a helper for IServiceCollection dependency injection that will add the required classes.

Every interface and method is documented with XML comments to make it easier to use.

• The base library has a single dependency, the Dependency Injection package.
• Easy to use
• Supported metrics
  • Counter
  • Gauge
  • Histogram
• Extendable
  • Everything exposed uses interfaces.
  • No sealed classes
  • No internal classes
• Permissive license, MIT
• Clean and consistent interfaces
• Small namespace so you don't bring in a bunch of stuff you won't need.
  • The namespace to use is Vecc.Prometheus. It currently only has 5 interfaces and 3 classes.
  • The guts of the project is all in Vecc.Prometheus.Internal. You will most likely will only need to bring in that namespace if you are extending the project.

You can find a simple and easy to follow example in the /src/Vecc.Prometheus.Example project.

• Examples
• Documentation
  • The methods are documented and an example project exists. It would be nice to see more well-rounded documentation around use cases.
• Additional packages
  • Simple extension methods for AspNetCore to expose it to Prometheus
  • Expose an additional http server endpoint to host the scrape
  • Push the scrape to an endpoint
