The Mechanics of Metrics

Track: Java Platform
Abstract Recording

The most efficient way to observe application behavior relies on metrics, key/value pairs of numerical data. Capturing and processing metrics can help you identify and respond to potential issues before they escalate and cause more serious problems, but doing that begs a few questions: What data points should you gather? Do custom metrics support SRE? Attendees will leave the talk with an understanding of how application metrics align with monitoring methods in a System Reliability Engineering context.

Erin learns (and teaches) by coding ridiculous things, like “Monster Combat”, an application that makes monsters fight each other to explore application metrics; “Game On!” (, a text adventure game for microservices; and a reactive workshop ( that munges ”The Jabberwocky” to gain an understanding of how reactive operators work.
