Introduction

A Throughput Quota Policy is a Quality of Service (QoS) policy that allows you to monitor web service throughput performance by specifying a throughput limit (quota) and queue size, and by configuring fault and alert notifications.

If the quota is exceeded, a Consumer Fault Message is returned to the service consumer and an alert is logged.
