This program reports query usage statistics by aggregating queries from MongoDB query profiler.
This program reports query usage statistics by aggregating queries from MongoDB query profiler.
The queries are the result of running:
```javascript
db.getSiblingDB("samples").system.profile.find({"op":{"$nin":["getmore", "delete"]}});
```
and then, the results are grouped by fingerprint and namespace (database.collection).
The fingerprint is calculated as the **sorted list** of the keys in the document. The max depth level is 10.
The last step is sorting the results. The default sort order is by ascending query count.
