This Refcard covers the three pillars of observability — metrics, logs, and traces — and how they not only complement an organization’s monitoring efforts but also work together to help profile, interpret, and optimize system-wide performance for distributed systems.

This guide explores:

• What is a distributed system?
• What is observability?
• How observability supports an entire organization
• Getting started with distributed system observability
• How to log and trace a distributed system
