This object reports the number of remote-access sessions that are currently active in the specific sense defined by the description, ready to actually carry application traffic between the user and the device, as opposed to a dormant session that is established but not currently passing traffic. It matters as the real-time load figure an admin compares against crasMaxSessionsSupportable to see exactly how much headroom remains before hitting the device's rated session capacity. A value consistently sitting near the device's maximum supportable sessions during business hours is the clearest possible signal that a capacity upgrade is needed soon.
