Path parameters

groupIdstring required
Example:32b6e34b3d91647abb20e7b8

Unique 24-hexadecimal digit string that identifies your project. Use the /groups endpoint to retrieve all projects to which the authenticated user has access.

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.

clusterNamestring required

Human-readable label that identifies the cluster to pin namespaces to.

clusterView'PRIMARY' | 'SECONDARY' | 'INDIVIDUAL_PROCESS' required

Human-readable label that identifies the cluster topology to retrieve metrics for.

Query parameters

envelopeboolean

Flag that indicates whether Application wraps the response in an envelope JSON object. Some API clients cannot access the HTTP response headers or status code. To remediate this, set envelope=true in the query. Endpoints that return a list of results use the results object as an envelope. Application adds the status parameter to the response body.

startstring date-time

Date and time when MongoDB Cloud begins reporting the metrics. This parameter expresses its value in the ISO 8601 timestamp format in UTC. Include this parameter when you do not set period.

endstring date-time

Date and time when MongoDB Cloud stops reporting the metrics. This parameter expresses its value in the ISO 8601 timestamp format in UTC. Include this parameter when you do not set period.

periodstring
Example:PT10H

Duration over which Atlas reports the metrics. This parameter expresses its value in the ISO 8601 duration format in UTC. Include this parameter when you do not set start and end.
