Recheck discovered resources before running a preview Chaos Studio Scenario

Source facts

Chaos Studio Workspaces and Scenarios are in public preview and are not intended for production use. A Workspace discovers resources within its subscription, resource-group or service-group scope and automatically picks up later additions and removals.

Actions run under the Workspace’s managed identity, not the operator’s personal credentials. Execution requires both permission to trigger the Scenario and the identity’s required target permissions. Reports identify which actions succeeded, failed or were skipped. Microsoft Learn.

Applicability

Limit this review to an authorized nonproduction preview evaluation. Identify the scope, Scenario configuration and current target population rather than relying on an old test plan.

DSE recommendation

DSE recommends comparing newly discovered resources with the intended failure exercise before allowing a run. Review identity grants against those exact targets and remove unexplained scope expansion from the proposed test. Assign stop conditions and application-health observations before execution. A saved Scenario should not silently authorize disruption of a resource that joined the scope after the original approval.

Verification

For an approved preview test, retain the reviewed target list, identity assignments and run identifier. Compare the action report with the intended resource set and investigate skipped or unexpected actions. Pair the report with the application’s own observations; a completed Scenario is not by itself evidence that the application recovered correctly. Reconcile any scope changes before the next run.
