ListLogGroups API Returns Incomplete Results for VCN/Subnet Audit Log Groups

[matthew-sonrai]

The LoggingManagementClient.listLogGroups() method returns incomplete results, specifically missing log groups associated with VCN/subnet audit logging, despite successful authentication and HTTP 200 responses.

Environment

• OCI Java SDK Version: 3.69.0
• Java Version: 8
• Authentication: User principal with tenancy-wide read permissions

Expected Behavior

Should return all log groups the authenticated principal can access, including VCN Flow Log audit groups.

Actual Behavior

• API returns HTTP 200 with valid response structure and request IDs

(super=com.oracle.bmc.logging.responses.ListLogGroupsResponse@be50ef52,opcNextPage=null,opcPreviousPage=null,opcRequestId=<request_id>,items=[])

• Same log groups are visible and accessible in OCI Console with identical credentials
• No authentication errors or exceptions
• OCI CLI shows identical behavior (missing same log groups)

oci logging log-group list --compartment-id "<compartment-id>" --region us-phoenix-1

Implementation

final LoggingManagementClient client = LoggingManagementClient.builder()
    .region(region)
    .build(new ConfigFileAuthenticationDetailsProvider(configFilePath, profile))

final ListLogGroupsRequest.Builder builder = ListLogGroupsRequest.builder().compartmentId(compartmentId);
String nextPage = null;
do {
  final ListLogGroupsRequest request = builder.page(nextPage).build();
  final ListLogGroupsResponse response = client.listLogGroups(request);
  response.getItems().forEach(logGroup -> {
    // Process discovered log groups - VCN audit log groups missing
  });
  nextPage = response.getOpcNextPage();
} while (!Strings.isNullOrEmpty(nextPage));

Request

Please investigate why the API filters out VCN/subnet audit log groups that are visible in Console with same permissions.
