Monitoring: The Math Behind Bad Behavior
LISA: Where systems engineering and operations professionals share real-world knowledge about designing, building, and maintaining the critical systems of our interconnected world.
The LISA conference has long served as the annual vendor-neutral meeting place for the wider system administration community. The LISA14 program recognized the overlap and differences between traditional and modern IT operations and engineering, and developed a highly-curated program around 5 key topics: Systems Engineering, Security, Culture, DevOps, and Monitoring/Metrics. The program included 22 half- and full-day training sessions; 10 workshops; and a conference program consisting of 50 invited talks, panels, refereed paper presentations, and mini-tutorials.

As we monitor more and more systems we can quickly become overwhelmed with data. Large systems today can generate many millions of measurements per second across millions of separate points of instrumentation. We’ve long surpassed human capacity of understanding the whole picture. Even with clever visualizations, the breadth of data is simply too much to reason about.
As our data feeds overflow our mental capabilities, we’re forced down one of two paths: explicitly collect less or implicitly surface interesting data. The latter is hard and requires a fair bit of math. In this presentation, I’ll talk about how we approach these numerical analysis problems and what you should and should not be able to expect.
