Specify MI Listeners

MI Listeners serve as routers between the Controller and a Performance Agent, and enable you to run Vusers over a firewall and to collect server monitor data and application diagnostics data over a firewall.

The MI Listener receives data from the Performance Agent at regular intervals. During the course of the test run, the Controller takes the data from the MI Listener to process as runtime data.

The MI Listeners are only available for load generators.
