I would like to add few tips that I found useful (few of them I learned during support session with screenconnect team).
I have these session groups created:
Computers categorized based on their hostname start. We have different standards for server and endpoints.
GuestMachineName LIKE 'SRV*'
Filters all servers starting with SRV as a single group
HostConnectedCount > 0
This helps me to manage who is connected, used in situations when I hit a license limit or want to know who specifically connected to which session
GuestClientVersion < '6.5' AND GuestConnectedCount > 0
This shows the machines that are online and have an outdated client version. I just need to issue a reinstall command for those outdated agents.
