Clear snapin history? Automatically?



  • I’ve decided to use Snapins as a sort of declarative state configuration (similar to DSC). As a result, my group of computers is scheduled to run all snapins every hour and is starting to make the snapin history page a bit largish. Is the best way to clear that via the database? Or have I missed something that can be done to clear it? Especially automatically would be cool. I’m assuming that I’ll need to make myself a script for cron to run though.

    If curious, my configuration does stuff like pulling the Primary User from FOG and making sure that that is the ONLY admin besides the 2 local admin accounts on each computer (adding/removing as needed). Also pulls bitlocker recovery information from the machine if its not already stored in FOG (or will enable bitlocker automatically if not presently enabled when I solve that debacle). You may be thinking, WTF??? And I agree with you. This deployment is interesting and they don’t have domain admin control. Not even GPO control. The office is part of a MUCH larger org, and fog has turned out to be best administrator solution.



  • @cml Better mark this as solved. Loved it!



  • @tom-elliott Thanks for the thoughts. And especially thank you for cml for the code, and Wayne for ALWAYS being amazing on the forums.

    I’m just happy that I solved my other problem on my own (the post about running 64bit powershell snapins so I can use modules and such). Gettin better all the time. Actually, Tom, it may be worth making a 64bit powershell snapin template. Guess that may have to be my own PR to put in.

    I think this could be handled with either method, though I think the DB procedure method is probably the least interfering. It wouldn’t rely on another service from Linux to be enabled and running at least.



  • A cron job could also run the last line of SQL that @cml posted on a schedule.

    The only way I could find to clear it was through the database.

    You could use the event scheduler to automatically clear the table.

    Here’s what I came up with to remove completed tasks older than a month.

    USE fog;
    CREATE EVENT clear_snapinTasks
    ON SCHEDULE AT CURRENT_TIMESTAMP + INTERVAL 1 MONTH
    DO
    DELETE FROM fog.snapinTasks WHERE stCompleteDate < DATE_SUB(NOW(), INTERVAL 1 MONTH);
