The following changes were applied to the source code:

• A build dependency for the micrometer library was added to the

build.gradle build file:

implementation("io.micrometer:micrometer-registry￾prometheus")

objects to let Prometheus know where to find the metrics:

prometheus.io/path: "/actuator/prometheus"
