Exchange monitoring shadow copy queues

Hi,
We are moving from Nagios to Cmk Standard 2.2.0p24 and we would like to monitor the queues in Exchange 2016.
I did select “setup/MS Exchange Message Queues”, created a new rule that only applies to the folder with Exchange servers.
I setup thresholds to 50 for warning and 100 for critical.
Is that the right way to do so?
Thanks a lot.
Nicky
