Update One Maintenance Window

Maintenance Window Considerations

Urgent Maintenance Activities Cannot Wait

Urgent maintenance activities such as security patches cannot wait for your chosen window. Atlas will start those maintenance activities when needed.

Once maintenance is scheduled for your cluster, you cannot change your maintenance window until the current maintenance efforts have completed.

Maintenance Requires Replica Set Elections
Atlas performs maintenance the same way as the manual maintenance procedure. This requires at least one replica set election during the maintenance window per replica set.
Maintenance Starts As Close to the Hour As Possible
Maintenance always begins as close to the scheduled hour as possible, but in-progress cluster updates or expected system issues could delay the start time.

PATCH /groups/{GROUP-ID}/maintenanceWindow

Request Path Parameters

Name Type Description
GROUP-ID string Unique identifier of the project from which you want to retrieve the Maintenance Window.

Request Query Parameters

This endpoint may use any of the HTTP request query parameters available to all Atlas API resources. These are all optional.

Name Type Description Default
pageNum integer Page number (1-based). 1
itemsPerPage integer Maximum number of items to return, up to a maximum of 100. 100
pretty boolean Indicates whether the response body should be in a prettyprint format. false
envelope boolean

Indicates whether or not to wrap the response in an envelope.

Some API 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, response body includes:

status HTTP response code
envelope The expected response body

For endpoints that return a list of results, the results object is an envelope. Atlas adds the status field to the response body.

If you set startASAP, all other body parameters are ignored.
