Original Description
Description:
This will add a new entry to the profiler: 'usedDisk'.
Engineering Ticket Description:
For an aggregation query using the {allowDiskUse:true} option, there is currently no way to determine if a given query used disk, and if so, how much disk space it used. We should add this information to the slow query log entry in the mongod log and to the database profiler output in system.profile.
