What is Log Analysis?

Log analysis is the process of reviewing, interpreting, and extracting meaningful insights from log data generated by computer systems, servers, applications, and network devices. These logs contain records of system events, user activities, errors, security breaches, and other essential information that can help organizations ensure smooth operations and secure environments.

Log files are typically stored in structured formats such as plain text, JSON, XML, or proprietary binary formats. They contain timestamped records, including:

• System events (startups, shutdowns, crashes)
• User activities (logins, file access, privilege changes)
