About
BSONSize Profiler computes the on-disk BSON size of each document in your collection and builds a P50/P75/P99 histogram. Outliers (documents above the 99th percentile) appear in a side list with the largest fields highlighted, so you can quickly identify the array field or embedded subdoc bloating your working set. Works against any collection — no special indexes required. Computes via aggregation pipeline with $bsonSize + $bucketAuto.
