So I am new to OpsView Pro. I have 5.2 up and running. I'm noticing for some service checks such as disk queue on host, I am not getting notifications. It is not an email issue. Postfix is configured and we are getting emails for example like when I restart the host and it reports that it is down. Also, investigating the host or the specific service check, OpsView doesn't show a notification in the notification tab either. Is there a setting that prevents notifications from being sent for certain things. I can see that this may be useful to make sure you aren't constantly spammed with "hiccups". I should add that the unreported alerts are usually a minute or less. They do show up in events just no notifications are sent.
