The Ultimate Guide to Cardinality for Observability

Technical Guide


Why should you learn about cardinality when building an observability practice?


Cardinality is an unavoidable consequence of scale that can't be solved by simply throwing more resources at it. This guide will help you understand what it is, why it impacts observability, as well as how to work with, and around the limitations of high cardinality performance data.

You'll also learn how to:

  • think of metrics as the edge of your telemetry
  • be consistent with attributes
  • treat your observability code
