How to check the current configuration of MongoDB?

MongoDBDatabaseBig Data Analytics

In order to check the current configuration of MongoDB, you can use getCmdLineOpts. The query is as follows −

> db._adminCommand( {getCmdLineOpts: 1});

The following is the output −

{ "argv" : [ "mongod" ], "parsed" : { }, "ok" : 1 }

In order to check live settings, you can use the below query −

> db._adminCommand({getParameter:"*"});

The following is the output &minus
