Hi People,
I wonder what's the best practice or the suggested Application Monitor Templates to combine for monitoring Active Directory servers?
I have got 16 Windows Server 2016 running AD domain controllers and FSMO role is installed in just one Virtual Machine.

Unfortunately, my available SAM license is not allowing me to monitor 16 of them.
What would be your suggestion?
My requirements are:
- Monitoring when the Active Directory services are down.
- Monitoring the AD replication issue.
- Monitoring & alerting for non-responsive AD domain controllers, which impact DHCP & DNS functionality.
Thank you in advance.
