[ovirt-users] Usage of Alerts, Events, Task information

Hello, there are some alerts that are automatically hidden (such as when I configure Power mgmt, the previous related alert go away), but not all. where to find info about their mgmt? I don't see anything special in "Introduction to Administration Portal" in RHEV 4.0 docs. Only that it is named "Alerts/Events Pane".... If I go to the line and right click I have Dismiss Delete All Display All How do they act exactly? If I select Display All, I get again what was automatically hidden (eg backup missing alerts and power mgmt conf missing alerts): how to re-hid them (I imagine dismiss, but I would like a global dismiss not one-by-one). Difference between dismiss and delete? Thanks in advance Gianluca
