Here is Brent Ozar’s SQL script to add important alerts: via Agent Alerts Not Configured – Brent Ozar Unlimited®
This script sets up SQL Server Agent alerts for severity 16 through 25 as well as specific alerts for 823, 824 and 825 errors.
Do a search & replace in this code and change ‘The DBA Team’ to the name of your SQL Agent operator – and remember, always use email distribution lists for your operator emails, not individual peoples’ emails. Someday – you’re going to go on vacation, and you want other people to get notified when you’re gone.
