Prerequisite knowledge

  • Engineering experience writing software with activity counters or other telemetry indicating user behavior (This applies to both UX/frontend developers who are tracking user behavior and backend/server side developers.)

What you'll learn

  • Understand that metrics are a complex set of types
  • Learn how to select among gauges, counters, and ratios to ensure you have the most effective analytics about you service

Description

The only thing worse than no metrics are bad or misleading metrics. Poor metrics distract you from finding root causes of outages and extend downtime. Well-designed metrics enable you to quickly know the state of your service to determine if your systems are healthy. Unfortunately, it isn’t always obvious what counts and how to count it.

Caskey Dickson covers the essential attributes of quality metrics, the kinds of statistics you can derive from them, and the valid ways that different metrics can be combined. Caskey walks you through the steps needed to capture metrics in a useful format while avoiding common pitfalls in metric design and outlines the principles of metric design, types of metrics, and when to use them. Join Caskey to learn about ratios, gauges, and counters; primary, secondary, proxy, and derived metrics; intervals and ordinals; and more.
