+|scrapeInterval|string|Configures the default interval between consecutive scrapes in case the `ServiceMonitor` or `PodMonitor` resource does not specify any value. The interval must be set between 5 seconds and 5 minutes. The value can be expressed in: seconds (for example `30s`), minutes (for example `1m`) or a mix of minutes and seconds (for example `1m30s`). The default value is `30s`.

The interval must be set between 5 seconds and 5 minutes. The value can be expressed in: seconds (for example `30s`), minutes (for example `1m`) or a mix of minutes and seconds (for example `1m30s`). It only applies to `PrometheusRule` resources with the `openshift.io/prometheus-rule-evaluation-scope=\"leaf-prometheus\"` label. The default value is `30s`.

 |enforcedLabelLimit|*uint64|Specifies a per-scrape limit on the number of labels accepted for a sample. If the number of labels exceeds this limit after metric relabeling, the entire scrape is treated as failed. The default value is `0`, which means that no limit is set.

+The `namespacesWithoutLabelEnforcement` property allows users to define recording and alerting rules that can query across multiple projects (not limited to user-defined projects) instead of deploying identical `PrometheusRule` objects in each user project.
+
+To make the resulting alerts and metrics visible to project users, the query expressions should return a `namespace` label with a non-empty value.
