define "alerts" please.
1. click on Alarms (top right)
2. shift + klick on your Alerts
3. click on menu (top left in this view)
4. Toggle acknowledged
If by "acknowledge alerts" you mean "mark events as reviewed," you can bulk-select events in your view (say, from a view containing all events from a particular data source) using either Shift or Ctrl to select multiple consecutive or non-consecutive events, respectively. Then, from the Menu dropdown, select Mark as reviewed > Selected.
it is the alarms from the bell icon on the top right. second answer was what i was looking for. only it is still limited by the amount of alarm on one page.
I don't have my notes handy but I think you can do this via command line. I'll reply back tomorrow with a database command that you can try and modify to do what you need.
