If you have a pool of relays being an F5, another downside is you can’t simply go report in WR or the console on how many clients are using Relay “x” because it’s no longer a 1:1 for client to Relay.
What I did is come up with a way to ask the Relay how many clients registered in the last 6 hours and then I just run a report on that property when viewing Relays.
if (exists relay service) then (number of rows of statement "select * from COMPUTER_REGISTRATIONS WHERE RegistrationTime >= strftime('%25s', 'now', '-6 hour')" of sqlite database of file (if windows of operating system then (pathname of parent folder of regapp "BESRelay.exe" & "\ClientRegisterData\registrationlist.db") else "/var/opt/BESRelay/ClientRegisterData/registrationlist.db")) else nothing
