Microsoft graph API for sign-in logs gets throttled when requested for large period ( 10- 30 days). Works fine when the period is small ( 1-5 days).
When the below query was requested we received 429 response code and the message "This request is throttled. Please try again after the value specified in the Retry-After header."
SignIn API (With 18days period) : https://graph.microsoft.com/v1.0/auditLogs/signIns?$orderby=createdDateTime asc&$filter=createdDateTime gt 2021-04-02T11:59:59Z and createdDateTime+le+2021-04-20T10:51:20Z
And based on Best practices to avoid throttling documentation, we did not exceed the request.
Does the throttling depends on the number of data being queried?

Please see https://learn.microsoft.com/en-us/graph/throttling?view=graph-rest-1.0#identity-and-access-reports-service-limits for why you might be throttled...
Hope this helps,
Dan.

Dan,
This "learn" article is all well and good for discussion of the limits, however I do not feel that it adequately addresses SharePoint Online Graph calls. Also there is some confusion about using x-ms-throttle-limit-percentage to cause delays when approaching the limit in calls that return DriveItemCollectionResponse objects. (SharePoint Graph calls). I understand that this feature is and has been Preview Only for some time.
Dan, The article you site does not address Graph calls which return Task of DriveItemCollectionResponse as in a Graph call to SharePoint. I have been searching for information on how to find the Retry-after and to be able to catch the limit percentage going above 80%.
