Introduction to Log Management
Log Management is the process of gathering, analyzing, and storing logs generated by various systems and applications. Logs are essential for monitoring system performance, troubleshooting issues, and enhancing security.
Importance of Log Management
Effective log management helps organizations maintain compliance with regulations, improve operational efficiency, and rapidly respond to incidents. By managing logs, businesses can:

Components of Log Management
Log management consists of three main components:
- Log Collection: The process of gathering logs from various sources, such as servers, applications, and network devices.
