Creation of monitoring rules for Windows OS

Good afternoon,
***
The goal is to create 3 rules for monitoring Windows Server.
You need to install System Center Operations Manager from scratch in a test environment (for you to check that the rules work), I do not need your test environment.
***
1 server with System Center Operations Manager 2025
1 client Windows Server 2019 or 2022 or 2025 (will be in the domain, fewer problems)
No assistance is needed for the installation.
***
Next, what is needed! Detailed screenshots with instructions for creating 3 rules
1) if the client is unavailable (agent offline) generate an email about the client's unavailability
2) if the client uses more than 80-90% of disk space (for all hard drives) generate an email

3) if the client loads the processor to 90% for more than 5 minutes generate an email
