    As we know cursor in mongoDB can be defined as return value of query run to mongoDB. The information of can be display using cursor.explain() function as show in below:

    db.collection.find().explain()

    The explain() method returns a document with the query plan and, optionally, the execution statistics. The output of this command look like: 

    {
    "cursor" : "BasicCursor",
    "isMultiKey" : false,
    "n" : 45,
    "nscannedObjects" : 45,
    "nscanned" : 45,
    "nscannedObjectsAllPlans" : 45,
    "nscannedAllPlans" : 45,
    "scanAndOrder" : false,
    "indexOnly" : false,
    "nYields" : 2,
    "nChunkSkips" : 0,
    "millis" : 74,
    "server" : "my-pc:27017",
    "filterSet" : false
}
