I have been working on some improvements to some of the regular ways we monitor for important changes. We always have to be on the lookout for unexpected changes being made in the SQL instances that we monitor since often times we are not the only team who has sysadmin access to the instance. We are always the best trained to take care of and configure things but we sometimes find that someone makes a change either to the SQL or database configuration without telling us. We want to know when things like this happen!
I’m a big fan of these. Of course you need to get the code right, as a bad trigger can be devastating but you can get a lot of useful information out of it and figure out who’s hand was in the cookie jar.
