When the Task is complete, user can find the LogEntry resource path in the HTTP header “Location” of the returned task monitor. This LogEntry resource tells user the basic information of the achieved Diagnostics Data. With Redfish X-Auth-Token(refer to POST – Create a session), user can download it by the URI indicated in the property “AdditionalDataURI” via HTTPS. Below is an example of the corresponding LogEntry resource.

{
    "OemRecordFormat": "Lenovo",
    "AdditionalDataSizeBytes": 18521125,
    "@odata.etag": "\"3bd1c929ad52266950f\"",
    "@odata.context": "/redfish/v1/$metadata#LogEntry.LogEntry",
    "Description": "This resource is used to represent a log entry for log services for a Redfish implementation.",
    "DiagnosticDataType": "Manager",
    "Name": "FFDC",
    "Created": "2022-09-19T02:57:53+00:00",
    "Id": "FFDC",
    "EntryType": "Oem",
    "@odata.type": "#LogEntry.v1_11_0.LogEntry",
    "@odata.id": "/redfish/v1/Systems/1/LogServices/DiagnosticLog/Entries/FFDC",
    "AdditionalDataURI": "/imm_dump/FFDC/7D72RCZ000_1234567890_xcc_220919-025717.tzz"
}

In this example, the achieved Diagnostics Data can be download by “https://<bmc_ip>/imm_dump/FFDC/7D72RCZ000_1234567890_xcc_220919-025717.tzz with Redfish X-Auth-Token.
