      Deploy a MongoDB atlas cluster that supports time series (>5.0). I've reproded on 6.0.10 and 7.0.1

       

      Create a timeseries collection

      Run the collStats command on the collection, observe that the correct namespace is reported

      Run the $collStats aggregation on the collection, observe that the reported collection name is prepended with system.buckets

      Deploy a MongoDB atlas cluster that supports time series (>5.0). I've reproded on 6.0.10 and 7.0.1   Create a timeseries collection Run the collStats command on the collection, observe that the correct namespace is reported Run the $collStats aggregation on the collection, observe that the reported collection name is prepended with system.buckets

      When a the $collStats aggregation is executed against a timeSeries collection, the namespace is reported as .<dbName>.system.buckets.<actualCollectionName>

      When the collStats command is run on the same collection, it correctly reports the namespace as <dbName>.<actualCollectionName>

       

      I've been able to reproduce this issue in MongoDB 6.0.10 and 7.0. Attaching example outputs from both the command and the agg stage
