+The following Service resource will be created upon certain conditions:
+- The ServiceMonitor integration is enabled
+- A Service resource must be created
+
+The reason for that is that the Ingress Controller would make it available to the outside
+sensitive data such as its metrics, and the operator wants to keep these data private
+(such as the value of "controller.service.enablePorts.stat=false").
+
+To let the Prometheus Operator being able to scrape the metrics, an additional service
+is going to be created, allowing it to expose of these in the internal Kubernetes networking.
