Hi all, I’m trying to create a custom alert in Nagios XI that triggers only when a virtual machine’s CPU usage stays above 85% for more than 10 minutes. I’ve tried using standard thresholds, but it seems to trigger immediately. Is there a recommended way to set up a delayed or sustained CPU usage alert specifically for VMs?
