Data and Log Space Alerts

  • Looking for a short article on setting up an alert in SQL Agent that pings someone when a data file reaches 80% full (or a log file). Short example, walk them through in SSMS and/or T-SQL

    Yeah, well...The Dude abides.
  • That isn't an article, and I'm looking to use the alerts that are built into SQL Server. It's more about alerts than space, and it's to put the content out there for beginners.

  • ok, I had left out the job part of it but if this is too much, I'll let it go.

    RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
    First step towards the paradigm shift of writing Set Based code:
    ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

    Change is inevitable... Change for the better is not.

  • Hey, hope I am not stepping on anyone's toes here.

    I have been looking into setting this up, so documented my steps and submitted an article.

    It is my 1st, so please be gentle. 🙂

    Hope it is along the lines of what you were looking for.

    Thanks.

  • Thanks, we'll take a look in a week or so. No one's submitted one yet.

  • I snooze, I lose!

    I'm just glad it got written. Take all the feedback with an open mind, it'll only make you better in the long run.
