Hi , i'm trying to monitor resource group history in Resouce manager
. But in not clear how to make it . What query i can use to monitor resource utilization during the night for consumer group ?
The field CONSUMED_CPU_TIME of the view DBA_HIST_RSRC_CONSUMER_GROUP.
The result of CONSUMED_CPU_TIME grow every day but some day the result is less of the day before .
It calculate the cumulative cpu usage ,
In certain hour , in the night tipically , nobody of the resource group is working but the cpu consumed continue to grow .
I need to know how much CPU was consumed, how much time was spent during I/O, how much Mb was read in small requests and in large requests... by each consumer group during each hour of each past day (no only the last few sessions), but I'm not able to find a query that can give me such informations.
