Computers Disappear / Reappear From the Current Performance And Load Across the Farm Dashboard
When running the Remote Desktop Commander Client, you experience a phenomenon where computers disappear and reappear from the Current Performance And Load Across the Farm dashboard.
This occurs because the Remote Desktop Commander agent service (RDPSoft RDR Agent Service) you have deployed on your session hosts is not sending over data it collects in a timely manner to the main system running Remote Desktop Commander, causing this dashboard to go out of sync. This is typically due to one of two reasons:
1.) Your session host servers are under so much load that our agent service takes too long to collect a data set, making it start to “run behind,” OR
2.) Networking between the system running the Remote Desktop Commander components and the session hosts is impaired in some way, either due to higher than typical latency, or a low level of network IOPS available. This results in too long of a data transfer time between our agent service and the main Remote Desktop Commander system.
The solution in both cases is to reduce the polling rate of Remote Desktop Commander. Please visit this KB article which shows you how to reconfigure our software to use one of two different lighter weight polling regimes (Polling Configurations 1 and 2).
