# Prometheus UI
By default, the [kube-state-metrics service](https://github.com/kubernetes/kube-state-metrics) provides a wealth of information about CPU and memory utilization to the monitoring application. These metrics cover Kubernetes resources across namespaces. This means that in order to see resource metrics for a service, you don't need to create a new ServiceMonitor for it. Because the data is already in the time series database, you can go to the Prometheus UI and run a PromQL query to get the information. The same query can be used to configure a Grafana dashboard to show a graph of those metrics over time.

To see what services you are monitoring, you will need to see your targets. Targets are set up by ServiceMonitors and PodMonitors as sources to scrape metrics from.

### Viewing the PrometheusRules
When you define a Rule (which is declared within a RuleGroup in a PrometheusRule resource), the [spec of the Rule itself](https://github.com/prometheus-operator/prometheus-operator/blob/master/Documentation/api.md#rule) contains labels that are used by Alertmanager to figure out which Route should receive a certain Alert.

weight: 5

there’s already a wealth of information provided by kube-state-metrics. Cpu utilization, memory utilization for different things across namespaces. If you just want resource metrics for prod, you don’t need to create a new ServiceMonitor for it. All you need to do is go to the prometheus UI and do a PromQL query to get the information.
In this section, you'll learn how to customize the Grafana dashboard to show metrics that apply to a certain container.
In the left navigation bar, click the icon with four boxes and click **Manage.**
- let’s say you want metrics that apply only for the container alertmanager.
- then you can do graphs of that over time.
- link to the promql queries used to make grafana dashboards. To get those queries,
- go to grafana
- right click on a graphic and click explore
