Dropwizard Prometheus module

Dropwizard bundle and reporter for Prometheus

Reporting to Prometheus Pushgateway

This module provides PrometheusReporter, which allows your application to constantly stream metric values to a Prometheus Pushway server:

final Pushgateway pushgateway = new Pushgateway("localhost", 9091));
final PrometheusReporter reporter = PrometheusReporter.forRegistry(registry)
                                              .prefixedWith("web1.example.com")
                                              .filter(MetricFilter.ALL)
                                              .build(pushgateway);
reporter.start(1, TimeUnit.MINUTES);

Prometheus servlet

You can also use PrometheusBundle, which starts a new admin servlet exposing metric values to a Prometheus server.

@Override
public void initialize(Bootstrap<DsnConfiguration> bootstrap) {
    bootstrap.addBundle(new PrometheusBundle());
}

After the Dropwizard application server start, a new endpoint /prometheus-metrics will be accessible with admin endpoint.
