What must rules in a workqueue be marked as to effectively catch errors?

Rules in a workqueue must be marked as active to effectively catch errors. When a rule is marked as active, it means that the workqueue will actively engage with that rule, enabling the system to monitor and evaluate conditions that may lead to errors. This active status facilitates real-time processing and error handling, ensuring that any issues can be captured and addressed promptly.

In contrast, other statuses like completed, deleted, or passive do not allow for effective error monitoring. Completed tasks no longer require action, deleted tasks are removed from consideration entirely, and passive status indicates that a rule is not currently engaged in the processing workflow. This makes it impossible for the system to utilize these rules for catching errors as they do not participate in the active processing needed to identify and manage problems within the workqueue.
