## Metadata{% #metadata %}

**Id:** `terraform-alicloud-rds-instance-log-duration-disabled` 

**Provider:** Alicloud

**Platform:** Terraform

**Severity:** Medium

**Category:** Observability

#### Learn More{% #learn-more %}

- [Provider Reference](https://registry.terraform.io/providers/aliyun/alicloud/latest/docs/resources/db_instance#parameters)

### Description{% #description %}

The `log_duration` parameter must be defined in the `parameters` array of `alicloud_db_instance` resources and set to `ON`. If `log_duration` exists and is set to `OFF`, the rule reports an `IncorrectValue` issue and suggests replacing `OFF` with `ON`. If the `parameters` array or the `log_duration` parameter is missing, the rule reports a `MissingAttribute` issue and suggests adding `parameters = [{ name = "log_duration" value = "ON" }]`.

## Compliant Code Examples{% #compliant-code-examples %}

```terraform
resource "alicloud_db_instance" "default" {
    engine = "MySQL"
    engine_version = "5.6"
    db_instance_class = "rds.mysql.t1.small"
    db_instance_storage = "10"
    parameters = [{
        name = "innodb_large_prefix"
        value = "ON"
    },{
        name = "connect_timeout"
        value = "50"
    },{
        name = "log_duration"
        value = "ON"
    }]
}
```
