Unable to Set Up FortiAnalyzer CPU/Memory Utilization Alert with Delay Threshold

Dear Community Members,

I hope you are all doing well.

I am trying to configure an event handler for CPU and memory usage that generates an alert when usage exceeds a defined threshold in FortiAnalyzer version 7.6.2 for connected FortiGate devices. However, I want to avoid alerts for brief spikes or hiccups. Specifically, I want the alert to trigger only if the CPU or memory usage remains above the threshold for 5 minutes or long.

Unfortunately, I’m having trouble implementing this logic and would appreciate expert guidance on how to achieve this setup. Please See attached screenshot. 

Thank you in advance for your support.
