ClickHouse Log Analysis (System Logs, Debug Logs, etc.)

What is Log Analysis?

Log analysis is an important task used to collect, process, and analyze system log data, helping to identify system performance issues, failure points, and more.

Classification of Log Analysis

System Log (System Log)

System logs refer to information recorded by the system regarding events related to itself or its dependent applications. This includes operating system logs, database logs, file system logs, and more.

Debug Log (Debug Log)

Debug logs are logs used during the development phase to help programmers determine if the current program has encountered errors or abnormal behavior.

Importance of Log Analysis

1. Performance Monitoring: By analyzing system logs, performance issues such as excessively high CPU usage or memory exhaustion can be identified.

2. Failure Point Localization: Analyzing logs helps determine failure points within the system, aiding in repair and optimization.

3. Security Monitoring: Analyzing logs can reveal abnormal activities, such as unauthorized access or malicious code execution.
