How to check whether the collection is sharded or not in Mongodb

Question

I Wrote

db.runCommand({enablesharding : "database"})

db.runCommand({shardcollection : "database.coll_1",key : {_id :"hashed"}})

And how to check is collection sahrded or not? Maybe exist some function that I do not know. Plese help me!

Answer 1

I Use the following :

use dbname db.colname.getShardDistribution()

Outputs the sharding distribution if it's sharded, and Collection dbname.colname is not sharded if it's not. Check this for more details.

I also use @Scott's comment aswell (use databaseName; db.collectionName.stats().sharded) but i prefer the getShardDistribution, it's cleaner.
