Alert when difference between value on 2 hosts greater than 50 percent

[Adacats]

I have 2 servers (hosts) and I need to create an alert so that when the difference in value (or load) between the 2 hosts is greater than 50 percent, it gives results (alerts).

How are you measuring / detecting the value of the load?

How often do you want to check?

Over what period do you want to measure the load?
