      From any mongos issue db.collection.stats() on an unsharded collection.

      Eg:

      > db.t2.stats()
{
	"sharded" : false,
	"primary" : "shard01",
	"ok" : 0,
	"errmsg" : "Database [bar] not found.",
	"$gleStats" : {
		"lastOpTime" : Timestamp(0, 0),
		"electionId" : ObjectId("5486a19daf76718dcc4f53ce")
	}

      From any mongos issue db.collection.stats() on an unsharded collection. Eg: > db.t2.stats() { "sharded" : false , "primary" : "shard01" , "ok" : 0, "errmsg" : "Database [bar] not found." , "$gleStats" : { "lastOpTime" : Timestamp(0, 0), "electionId" : ObjectId( "5486a19daf76718dcc4f53ce" ) } }

      As part of SERVER-12419, we created a new field name called "$gleStats".

      The leading $ sign on the field name breaks the document conventions. This means that end users cannot take the output of db.collection.stats() on a MongoS and re-insert it or perform other operations with this output.
