- top¶
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
- getmore
- insert

- commands
Issue the top command against the admin database in the form:
{ top: 1 }

At the mongo shell prompt, use top with the following evocation:
db.adminCommand("top")
Alternately you can use top as follows:
use admin
db.runCommand( { top: 1 } )

{
"totals" : {
"records.users" : {
"total" : {
"time" : 305277,
"count" : 2825
},
"readLock" : {
"time" : 305264,
"count" : 2824
},
"writeLock" : {
"time" : 13,
"count" : 1
},
"queries" : {
"time" : 305264,
"count" : 2824
},
"getmore" : {
"time" : 0,
"count" : 0
},
"insert" : {
"time" : 0,
"count" : 0
},
"update" : {
"time" : 0,
"count" : 0
},
"remove" : {
