top is an administrative command that returns usage statistics for each collection. top provides amount of time, in microseconds, used and a count of operations for the following event types:
- total
- readLock
- writeLock
- queries

- commands
Issue the top command against the admin database in the form:
{ top: 1 }
Example¶
At the mongo shell prompt, use top with the following invocation:
db.adminCommand("top")
Alternately you can use top as follows:
use admin
db.runCommand( { top: 1 } )
The output of the top command would resemble the following output:

"count" : 1
},

"count" : 2824
