How Do You Eat An Elephant? - RICON East 2013 

by Theo Schlossnagle & Robert Treat

When OmniTI first set out to build a next generation monitoring system, we turned to one of our most trusted tools for data management; Postgres. While this worked well for developing the initial Open Source application, as we continued to grow the Circonus public monitoring service, we eventually ran into scaling issues. This talk will cover some of the changes we made to make the original Postgres system work better, talk about some of the other systems we evaluated, and discuss the eventual solution to our problem; building our own time series database. Of course, that's only half the story. We'll also go into how we swapped out these backend data storage pieces in our production environment, all the while capturing and reporting on millions of metrics, without downtime or customer interruption.
