<p>Detects whether a stack's actual configuration differs, or has <i>drifted</i>, from it's expected configuration, as defined in the stack template and any values specified as template parameters. For each resource in the stack that supports drift detection, CloudFormation compares the actual configuration of the resource with its expected template configuration. Only resource properties explicitly defined in the stack template are checked for drift. A stack is considered to have drifted if one or more of its resources differ from their expected template configurations. For more information, see <a href="https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-stack-drift.html">Detecting Unregulated Configuration Changes to Stacks and Resources</a>.</p> <p>Use <code>DetectStackDrift</code> to detect drift on all supported resources for a given stack, or <a>DetectStackResourceDrift</a> to detect drift on individual resources.</p> <p>For a list of stack resources that currently support drift detection, see <a href="https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-stack-drift-resource-list.html">Resources that Support Drift Detection</a>.</p> <p> <code>DetectStackDrift</code> can take up to several minutes, depending on the number of resources contained within the stack. Use <a>DescribeStackDriftDetectionStatus</a> to monitor the progress of a detect stack drift operation. Once the drift detection operation has completed, use <a>DescribeStackResourceDrifts</a> to return drift information about the stack and its resources.</p> <p>When detecting drift on a stack, CloudFormation doesn't detect drift on any nested stacks belonging to that stack. Perform <code>DetectStackDrift</code> directly on the nested stack itself.</p>
