After choosing MongoDB from the Data Sources list, the MongoDB Data Source page will be displayed, and the user needs to enter the following connection information:

• Name: The Data Source name
• Connection String: The format of the connection string, that is, mongodb://username:password@hostname:port/dbname?options

We will describe the fields of the connection string shortly:

• The username:password@ is optional. If given, the client will attempt to log in using these credentials to a database after connecting to the Mongo DB server.
• The port is the port that MongoDB is listening to. By default, the port is 27017, unless specified otherwise.
• The hostname is the only required field in the connection string. This is the host name or IP address of the MongoDB server.
• The dbname is optional. This is the database name to authenticate when the connection string consists of the database credentials (username:password field).
  Note: If dbname is not given in the connection string, but the credentials are specified, the client will authenticate to the admin database using those credentials.
• ?options are connection-specific options. The options are specified in the form of name-value pairs. Pairs are seperated by &. For example, a connection string with enabled SSL and self-signed certificates is as follows:
  mongodb://username:password@hostname:port/dbname?ssl=true&ssl_cert_reqs=CERT_NONE.

• For more details and options, please refer to the MongoDB documentation.
• Database Name: The name of the database to log in to. The database name is also included in the connection string, although it is optional. A separated field for the database name is usually required when using shared hosts.
• Replica Set Name: The name of the replica set (in case your MongoDB is set up in production deployment, you should have replica sets for redundancy and high availability).
