This talk evalutes some easy ways to extract useful trending and capacity planning out of your existing monitoring investment. Using Nagios performance data, we examine simple behaviors with PNP4Nagios and graduate on to more insightful analytics with Graphite. With metrics in hand we look at the questions that IT /should/ be asking, such as:
* What sort of data should I trend?
* Why do I need to trend it?
* How do Operational or Engineering trends relate to Business or Transactional monitoring?
* How does this data impact our customer relationship and/or their bottom-line?
Finally, we look at creative ways to get profiling data out of your production systems with a minimum amount of effort from your development team.
