Specifies a global limit on the number of scraped samples that will be accepted. This setting overrides the SampleLimit value set in any user-defined ServiceMonitor or PodMonitor object if the value is greater than enforcedTargetLimit. Administrators can use this setting to keep the overall number of samples under control. The default value is 0, which means that no limit is set.
