Thank you cjoseph for your suggestion.
In my case this uptime report is not very useful.
Nevertheless I found the way to make what I needed. Maybe for someone will be helpful.
As I mentioned before I am already had triggers on Device up/Device done. So all AMP Alerts on Up/Down I found in System > Alerts.
Lastly I download export CSV file and import to Excel.
I hope for somebody this information will be helpful.
Good luck
