Learning Objectives
- Understand the importance of monitoring MongoDB replication.
- Learn how to use MongoDB commands to check replica set health and status.
- Identify key metrics such as replication lag and member state.
Introduction
Replication is a core feature of MongoDB that ensures data redundancy and high availability by copying data across multiple servers called replica set members.
Monitoring replication is essential to detect issues early, maintain data consistency, and ensure your database cluster remains healthy and performant.
