Event Modeling Over Time

I had to haul this one out again today: time-based event modeling. In a nutshell, I was looking for patterns, and I was looking for some sort of variation in the patterns to figure out what on earth might have changed. It's useful for a case where no one thing went wrong; the system just slowly churned itself into the ground. And so I figure out how this slow spiral started by looking at the heartbeat of the system, and following it down.

By the way, this is hard work. Make sure you have some time to focus when you go to do it.
