Centralized Logging Concepts

Imagine you have many applications running on different servers. Each application generates logs locally. How do you find a problem that spans multiple services?

Centralized logging is the answer! It's a system that collects, processes, and stores logs from all your applications in one accessible place.

When logs stay on individual servers, finding issues becomes a nightmare. You'd have to:

• Log into each server separately.
• Search through potentially huge, unstructured log files.
• Manually correlate events across different machines.

This is slow, error-prone, and nearly impossible in modern distributed systems.
