# Log Aggregation

Log aggregation is the process of collecting, centralizing, and combining log data from multiple servers, services, or sources into a single unified system for analysis.

## What Is Log Aggregation?

Log aggregation is the practice of collecting log files from multiple sources — web servers, application servers, CDN edge nodes, load balancers — and combining them into a single centralized location. This gives you a complete picture of all requests hitting your infrastructure, regardless of which server handled them.

## Why It Matters

Modern websites often run across multiple servers behind a load balancer, with CDN nodes worldwide. Without log aggregation, your crawl data is fragmented across dozens of files on different machines. You cannot accurately count Googlebot visits or analyze crawl patterns unless you aggregate all logs first. Aggregation is also essential for correlating events across your stack.

## How to Aggregate Logs

Common approaches include shipping logs to a central server using tools like rsyslog, Fluentd, or Filebeat. For simpler setups, you can download logs from each server and merge them locally. [LogBeast](/logbeast/) can import logs from multiple files and servers, automatically deduplicating and merging entries into a unified timeline for analysis.
