Avg. User Logon Brokering Time

Summary

Monitors the average user logon brokering time (in seconds) for a delivery group.

Brokering is a process that allows a user to click a desktop or application resource, and have a 'worker' (server or desktop machine) selected and prepared for an inbound ICA/HDX connection. During brokering process, the Broker Service is responsible for negotiating session launch requests with delivery group machines. The Broker Service communicates with the VDA agent over a CBP (connection brokering protocol) protocol to validate a machine’s readiness to fulfil a session launch request, gather the necessary details (IP address or host name), and send the details to the StoreFront site to be packaged and delivered as an '.ICA' launch file that’s consumed by the Receiver.
