MongoDB 3.2.11{quot；ok"；0，"；errmsg"；："；没有这样的cmd:top"；，"；代码"；59}

我们运行一个分片集群

MongoDB shell version: 3.2.11
connecting to: localhost:27017/test
mongos> db.adminCommand("top")
{ "ok" : 0, "errmsg" : "no such cmd: top", "code" : 59 }
mongos> use admin
switched to db admin
mongos> db.runCommand( { top: 1 } )
{ "ok" : 0, "errmsg" : "no such cmd: top", "code" : 59 }

根据我们的版本，此命令应该存在

top是一个管理命令，用于返回 每个集合。top提供使用的时间量（以微秒为单位） 以及以下事件类型的操作计数

执行此命令的用户具有

ClusterMonitor

权限。我尝试使用root/admin用户，但收到了相同的错误
