Note

Feature unavailable in Free and Shared-Tier Clusters

This feature is not available for M0 free clusters, M2, and M5 clusters. To learn more about which features are unavailable, see Atlas M0 (Free Cluster), M2, and M5 Limitations.

Note

Groups and projects are synonymous terms. Your {GROUP-ID} is the same as your project ID. For existing groups, your group/project ID remains the same. The resource and corresponding endpoints use the term groups.

The Atlas Administration API authenticates using HTTP Digest Authentication. Provide a programmatic API public key and corresponding private key as the username and password when constructing the HTTP request. To learn how to configure API access for an Atlas project, see Get Started with the Atlas Administration API.

Request

Base URL: https://cloud.mongodb.com/api/atlas/v1.0

GET /groups/{GROUP-ID}/clusters/{CLUSTER-NAME}/processArgs

Request Path Parameters

Path Parameter	Type	Necessity	Description
GROUP-ID	string	Required	Unique identifier for the project containing the cluster you want to retrieve.
CLUSTER-NAME	string	Required	Name of the cluster to retrieve.

Request Query Parameters

This endpoint might use any of the HTTP request query parameters available to all Atlas Administration API resources. All of these are optional.

Name

Type

Necessity

Description

Default

pretty

boolean

Optional

Flag indicating whether the response body should be in a prettyprint format.

false

envelope

boolean

Optional

Flag indicating if Atlas should wrap the response in a JSON envelope.

This option may be needed for some API clients. These clients cannot access the HTTP response headers or status code. To remediate this, set envelope=true in the query.

For endpoints that return one result, the response body includes:


status	HTTP response code
envelope	Expected response body

false

Request Body Parameters

This endpoint does not use HTTP request body parameters.

Response

Name	Type	Description
defaultReadConcern	string	Default level of acknowledgment requested from MongoDB for read operations set for this cluster. MongoDB 4.4 clusters default to available.
defaultWriteConcern	string	Default level of acknowledgment requested from MongoDB for write operations set for this cluster. MongoDB 4.4 clusters default to 1.
failIndexKeyTooLong	boolean	Flag that indicates whether you can insert or update documents where all indexed entries don't exceed 1024 bytes. If you set this to `false`, `mongod` writes documents that exceed this limit but doesn't index them. This option corresponds to the `failIndexKeyTooLong` `mongod` parameter.
javascriptEnabled	boolean	Flag that indicates whether the cluster allows execution of operations that perform server-side executions of JavaScript. If your cluster runs a MongoDB version less than 4.4, this option corresponds to modifying the `security.javascriptEnabled` configuration file option for each `mongod` in the cluster. If your cluster runs MongoDB version 4.4 or greater, this option corresponds to modifying the `security.javascriptEnabled` configuration file option for each `mongod` and `mongos` in the cluster.
minimumEnabledTlsProtocol	string	Minimum Transport Layer Security (TLS) version that the cluster accepts for incoming connections. Clusters using TLS 1.0 or 1.1 should consider setting TLS 1.2 as the minimum TLS protocol version. To learn more, see What versions of TLS does Atlas support?. This option corresponds to the `net.ssl.disabledProtocols` `mongod` configuration file option.
noTableScan	boolean	Flag that indicates whether the cluster disables executing any query that requires a collection scan to return results. This option corresponds to the `notablescan` `mongod` parameter.
oplogSizeMB	integer	Storage limit of cluster's oplog expressed in megabytes. A value of `null` indicates that the cluster uses the default oplog size that Atlas calculates. To check the oplog size: Connect to your cluster via `mongosh`. Authenticate as a user with the `Atlas admin` role. Run the `rs.printReplicationInfo()` method to view the current oplog size and time. This option corresponds to the `replication.oplogSizeMB` `mongod` configuration file option.
sampleSizeBIConnector	integer	Number of documents per database to sample when gathering schema information. This parameter corresponds to the sampleSize mongosqld option.
sampleRefreshIntervalBIConnector	integer	Interval in seconds at which the mongosqld process re-samples data to create its relational schema. This parameter corresponds to the sampleRefreshIntervalSecs mongosqld option.
