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.
So it seems then problems detection is fine, issue is with alerting profile.
If you have this option configured that way it should work in general. I understand, that you don't have any filters enabled for alerting profiles? Custom alerts is for custom thresholds in general.
Initially it didn't work the way as in the attachment you sent, so I tried adding tags to the host and applied filters with tag in alerting profile that also didn't work. Now I removed filter and tried again after you had sent the attachment, It worked!(I got mails for availability alert) I didn't understand why it was not working earlier without filters.
I added tag to the host and then in filters I tried both the options "Only Include entities that have any tag" and "only include entities that have all tags". It shows in problems but I didn't get any mail. Is there any other specific configuration needed when we apply filters with tags in alerting profile?
Ok try this, create management zone that will contains entitites you want to track with those alerts.
And than create alerting profile with such filter:
All should be replaced by your Management Zone name. In general I always recommend using management zones as filters, because you have only single place to configure filters for whole tenant.
