SQL Server Agent has a built-in alerting process for when jobs fail, but the information it provides isn’t very useful. You’re only told which job, what time, who ran it, and which step failed. If you want to see why it failed, you have to review the job history manually. On a busy system with a lot of frequently run jobs, the job history could have cleared down by the time you go and look at it, especially if you’ve left the job history thresholds at the SQL Server defaults, something we routinely pick up in our Database Reviews.
