+# huaweicloud_rds_slow_log_files
+
+Use this data source to get the list of RDS slow log files.
+
+## Example Usage
+
+```hcl
+variable "instance_id" {}
+
+data "huaweicloud_rds_slow_log_files" "test" {
+  instance_id = var.instance_id
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `region` - (Optional, String) Specifies the region in which to query the resource.
+  If omitted, the provider-level region will be used.
+
+* `instance_id` - (Required, String) Specifies the ID of the instance.
+
+## Attribute Reference
+
+In addition to all arguments above, the following attributes are exported:
+
+* `id` - The data source ID.
+
+* `files` - Indicates the list of slow log files.
+
+  The [files](#files_struct) structure is documented below.
+
+<a name="files_struct"></a>
+The `files` block supports:
+
+* `file_name` - Indicates the file name.
+
+* `file_size` - Indicates the file size in bytes.
