Mary Jo Sminkey: Hi Mike!
Michael: Hey, so let's start off with the 64,000 pound elephant in the room because I bet not everyone listening is doing error logging, and why should they be doing it?
Mary Jo Sminkey: Well, basically when you get customers from emails, from your … Sorry from your customers, or your clients, usually they have absolutely no detail. They just say your website sucks, it's broken, I can't check out. They give you no detail at all. If you've ever tried to get some details from your customers, it usually fails miserably. My goal has always been how can I get enough information about what's happening for the users on the website that I can debug those errors without having to ask them for help because they are going to be absolutely no help at all.
In old days, a lot of us would just check ColdFusion error logs, or email the CF error dump to ourselves. Our applications have gotten a lot more complicated. There's a lot more components to it, so this is often not enough information. My goal has been to continually, gradually, incrementally improve what I'm doing for my, not just my error logging, but the way I notify myself of errors, what's included in that information, and how I can collect enough information about what's going on that I can figure out what the problem is, and fix it.
