array[string]

query

False

Specify the fields to return.

max_records

integer

query

False

Limit the number of records returned.

return_records

Error

Status: Default

ONTAP Error Response Codes

Error Code Description

124519405

The activity tracking report for SVM svm.name returned zero records. Check whether the activity tracking enabled volumes belonging to the SVM have read/write traffic. Refer to the REST API documentation for more information on why there might be no records.

124519406

Failed to get the activity tracking report for SVM svm.name. Reason:.

124519407

SVM wildcard queries are not supported for activity tracking reports.

124519408

Activity tracking is not supported on SVM svm.name, because it is configured as a destination for SVM DR.

124519409

Activity tracking is not supported on SVM svm.name, because it is configured as a destination of a MetroCluster SVM relationship and the SVM admin state is stopped.

Also see the table of common errors in the Response body overview section of this documentation.
