Log aggregation is the process of collecting and centralizing log data from various sources into a single system where it can be processed, stored, and analyzed. Logs are generated by software systems, applications, services, and infrastructure components, and they provide valuable insights into the behavior and performance of these systems. Aggregating these logs involves gathering them from different servers, applications, and environments to offer a unified view of all system activities. This allows developers, system administrators, and security teams to monitor, troubleshoot, and maintain the system more efficiently.
