Gets all detectors or a single detector if a <code>detectorId</code> is specified. This is a paginated API. If you provide a null <code>maxResults</code>, this action retrieves a maximum of 10 records per page. If you provide a <code>maxResults</code>, the value must be between 5 and 10. To get the next page results, provide the pagination token from the <code>GetDetectorsResponse</code> as part of your request. A null pagination token fetches the records from the beginning.
