Prometheus Trait
The Prometheus trait configures a Prometheus-compatible endpoint. It also exposes the integration with a Service
and a ServiceMonitor
resources, so that the endpoint can be scraped automatically, when using the Prometheus
operator.
The metrics exposed vary depending on the configured runtime. With Quarkus, the metrics are exposed using MicroProfile Metrics. While with the default runtime, they are exposed using the Prometheus JMX exporter.
The creation of the ServiceMonitor resource requires the Prometheus Operator
custom resource definition to be installed.
You can set service-monitor to false for the Prometheus trait to work without the Prometheus operator.
