I would like to know if there is a way to export (to csv, txt file) the result of a historical query on alarm subconsole.
Just select the alarms and hit ctrl + c.
Personally, I'd run a SQL query of nas_transaction_summary or nas_transaction_log to export the pertinent info. It'll look a little better in an excel spreadsheet.
Actually hightlight all your alarms/ right click, edit/copy to clipboard. From there open excel and paste. Will put all fields in there own column.
