 1. Identify sources which are not critical data sources where stricter data controls can be added to prevent your organization from being throttled.
 1. Identify `_sourceCategory` or any other identifier for the sources.
 1. Run the following query. The goal of this query is to understand previous data ingestion trends and suggest to you the peak volume seen per minute.
-   ```sql
-   {Your scope for data, example: _sourceCategory= alpha }
-   | timeslice 1d
-   | sum(_size) as datasize by _timeslice
-   | sort by datasize desc
-   | limit 1
+   ```sql    
+    _sourceCategory=<source category> AND _index=<partition name>
+    | timeslice 1m
+    | sum(_size) as bytes by _timeslice
+    | bytes/1Mi as mbytes
