An ARM is a time-based flow rate rule. These are ARM rule attributes:
| Attributes | Description |
|---|---|
| Time Unit | Time period for request rate (second, minute, hour). |
| Limit | Maximum request rate per time unit (3 requests per minute). |
| Qualify Time | Number of seconds that the current ARM rate must continuously remain at or above the limit before action is taken. A zero value means action is immediately taken as soon as the limit is reached. |
| Qualification | Common classification criteria (Request Source, Query Characteristics, Target, and Query Band) can be specified to target specific types of requests (user, application, table scans, processing time, and so on). |
| Action | Rule action performed when Limit and Qualify Time conditions are met. Actions include Delay, Reject, and Logging (warning mode). Limit, Reject, and Delay action attributes are state-dependent values. |
Logging (warning mode) is similar to that of Filters. See Warning Mode.
