As a SQL Server DBA, especially Production/Operations DBA in a relatively large environment, , sooner or later you are going to run into runaway SQL agent jobs or sometimes take longer to complete than they should (for example, longer than the SLAs, whether formal or informal) and/or affect some other jobs, other queries, applications, users etc.
Or maybe you have other reasons to know what jobs are running and for how long. Generally you would use the Job Activity Monitor in the SQL Server Management Studio. I do too, almost exclusively. But there are certain SQL instances and situations I run into when I need something automated, and get alerted by email if any of the jobs are running for more than X amount of time.
If you have a third party monitoring tool that provides the functionality, great. Or maybe you have a better solution of your own, more suitable for your needs. If not, below is what I have used from time to time at different organizations I have worked for over the years.
This SQL script is convenient and very simple, in other words nothing fancy about it but it gets the job done.
Informally, I have divided the script into two parts, one checks for the active jobs and the other part sends out an email. You can run the whole script at once or run the first part first, review the results on the screen and then if you would like it to send email, highlight the second part and run it on it's own (while still remaining in the same SSMS window/session though).
