Monitor and Alert SQL Stack dumps

As many of know not all stack dumps raise an error in SQL Server and may go unnoticed for days, SQL stack dumps can sometimes cause database corruption and its always better to analyse the server immediately after a stack dump. Since there are no errors raised we cannot configure normal SQL Alert to report the SQL Stack dumps, I created a PowerShell script which can also be scheduled as a SQL Agent job to monitor the SQL Stack dumps, I have used Chad Millers invoke-sqlcmd2 just for flexibility in the future, you can use native invoke-sqlcmd without any issue. 

 If you want to schedule this script as SQL Agent job remember to comment the clear-host and the invoke-sqlcmd2 function in the below script and try to use invoke-sqlcmd instead.Also I have scripted this to check the stack dumps for last one hour as I am running the SQL agent every hour in my environment, please change accordingly.

    This is to diminish the danger of SIDS. Probably the best technique to ensure that your infant is in acceptable position while dozing is having rest screens to monitor his developments while dozing.http://beitragpost.com/best-portable-monitor-2021-usb-screens-for-working-from-home/

    For any individual who doesn't as of now use CommentLuv this post gives an extraordinary summation of the module and you feature the advantages and its helpfulness very well to be sure.

    I particularly like how you discussed catchphrases. This is an element that I haven't utilized at this point, chiefly in light of the fact that I haven't actually been sure about how to utilize it appropriately. In any case, your basic clarification shows how straightforward it truly is. So I will have a go at doing it in this remark and trust that it works OK 🙂
