ELK Alerting on one of the host memory high utilization

How to set up an alert for a server when RAM/CPU reaches a threshold (like 85%)

What have you tried so far? Alerting | Kibana Guide [7.16] | Elastic should be able to do what you want though.

Hi,
I am using freeware version of it on standalone machine on Windows 10 Pro.
Metricbeat is showing the details but when in click on Security>Alerts: it says Detection engine permission required (You do not have the required permissions for viewing the detection engine)
