Motivation
org.apache.pulsar.broker.resourcegroup.ResourceGroup.PerMonitoringClassFields#usedLocallySinceLastReportholds the usage rate of ResourceGroup in the current cycle.When the report thread calls the
org.apache.pulsar.broker.resourcegroup.ResourceGroup#rgFillResourceUsageto report the ResourceGroup usage, theusedLocallySinceLastReportshould be reset.Right now, this value will be reported every 2 cycles. The correct behavior should be to report the current rate only when it exceeds or falls below 5% of the last reported value.
#22340 breaks this behavior.
