I have created a alerting profile and for severity rule --> availability i left threshold 0 minutes. But I didn't get any notification when the app or host is down.

Yes I meant Dynatrace. I did email integration with alerting profile. I got mails for alerts like(which i created using settings-->anomaly detection-->custom events for alerting) disk usage,request count . But for availability severity i didn't knew what option to specify in settings-->anomaly detection-->custom events for alerting. So in process group settings --> availability settings of host, I have selected option "if any process becomes unavailable" for "open new problem" then In problems, it started notifying when the host is down but I am not receiving mails.
