URL: https://github.com/apache/rocketmq/issues/5615

   version: 
      rocketmq 4.8.0
      rocketmq-exporter
   
   Q: when i use rocketmq exporter to collect rocketmq cluster 
metrics(collection period is one minute), i find that the 
putMessageDistributeTime of broker is not correct by calling 
fetchBrokerRuntimeStats. And then i reviewed StoreStatsService, 
putMessageDistributeTime could be initialized every minute when calling 
printTps method. if exporter's collection time is different from 
StoreStatsService printTps time, user will get incorrect 
putMessageDistributeTime.
   
   how to fix:
   we should record old putMessageDistributeTime when init 
putMessageDistributeTime every time. when calling fetchBrokerRuntimeStats to 
get putMessageDistributeTime, we should return the old putMessageDistributeTime.
