I need to get the email alert when nodes or apps down.
I used the default alert and edit it.
the things that I've set are
1. Monitored network objects tab - I chose just th nodes I need to monitor
2. Alert trigger - checked "Send Alert any time Status changes"
3. Action tab - entered my email and mail server
that's all I 've done. For the other tabs, I leave it all default.(alert suppression tab is still default "do not configure alert suppression for this alert")
