I was looking at simply setting up your recommended mysql metrics “queries per second, number of connections, and number of queries running” to be collected and stored in Graphite and then (naively??) setting up some comparison function to indicate problems.

However, I see that in the notes for your upcoming Velocity talk “Quantifying Abnormal Behavior” (http://velocityconf.com/velocity2013/public/schedule/detail/28118) you state “Why control charts, Holt-Winters, trending, etc are NOT the right approach”.

I’m curious where you are at on this. Any thoughts or do we have to wait for your Velocity talk?

Great Stuff all around!

There is an important twist, though, which I’ll follow up on in another blog post.

Knowing that would have enabled me to find a huge variety of fascinating research on this topic.
