As we work on increasing the number of concurrent tests that agents can run, we've made some changes to the task queueing and execution model. For the most part, this won't change anything from the perspective of a user, but it does change how utilization is calculated. We've consolidated the separate queues for HTTP Server, DNS and Network tests to a single queue, and done the same for Page load and Transaction tests. These new utilization queues can be seen by opening the Agent Settings page, selecting an agent, and checking the Agent Utilization charts shown in the lower right hand corner of the expanded section.
