Description

Introduction

Monitoring and observability are critical components of managing distributed systems like YugabyteDB. Effective monitoring ensures that system performance is optimized, issues are detected early, and high availability is maintained. YugabyteDB offers a rich set of tools for monitoring cluster health, performance metrics, and query execution in real-time, helping users troubleshoot and optimize their deployments.

Prerequisites of YugabyteDB

• Basic knowledge of distributed databases.
• Familiarity with YugabyteDB architecture and components.
• Understanding of database performance metrics and monitoring concepts.
• Experience with cloud platforms and container orchestration (e.g., Kubernetes) is beneficial.
