Arrival Rate Meters (ARMs) are TASM rules that provide a way to regulate the flow of requests admitted by TASM into the system. An ARM rule specifies the maximum number of requests per time unit that TASM will admit into the system. Qualification criteria can be used to target specific types of requests. For example, three rquests per hour for requests with estimated processing time of more than one hour.

The TDWM order of processing is:

  1. Filters
  2. ARMs
  3. Throttles
