Analyzing the errorlog

How often do you do this? Look over each message (type) in the errorlog file and determine whether this is something you want to act on. Sure, some (but not all) of you have some monitoring solution in place, but are you 100% confident that it really will notify for all messages that you might find interesting? That there isn’t even one little message hiding in there that you would find valuable knowing about? Or how about messages that you typically don’t are about, but knowing that you have a high frequency can be valuable information?

So, this boils down to actually reading the errorlog file. Some of you probably already have scripts and tool that makes this easier than just reading every simple message from top to bottom. I wanted to share how I do it, and this is why I wrote my Analyze SQL Server logs article. Check it out. And, feedback is always welcome!
