if there is already an account set up you can find by going to Metrics -> Setting the metric to Total Request Units -> The Locale to 30 days -> Aggregation to Max. And then add a filter for the container you want to measure. The max figure is the highest consumed RU's Metric
When the Max is identified, you can base your Allocated RU's on that container

2023-09-21T19:47:45.8166667+00:00 @siddharth bansal you can use these metrics to see the individual operations that are causing the RU's select Total Requests as the metric and select apply splitting and filter by Operation
Check and let me know if you are able to get.
