Chapter 10. ServiceMonitor [monitoring.coreos.com/v1] Description The ServiceMonitor custom resource definition (CRD) defines how Prometheus and PrometheusAgent can scrape metrics from a group of services. Among other things, it allows to specify: * The services to scrape via label selectors. * The container ports to scrape. * Authentication credentials to use. * Target and metric relabeling. Prometheus and PrometheusAgent objects select ServiceMonitor objects using label and namespace selectors. Type object Required spec 10.1. Specification Property Type Description apiVersion string APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values.
