🔧 Server Logs Guide
Server logs are essential for monitoring, troubleshooting, and auditing your application. They record events, errors, and user activities, providing valuable insights into system behavior.
📝 What Are Server Logs?
Server logs are files that store information about your server's operations. Common log types include:
- Access logs (记录访问请求)
- Error logs (记录错误和异常)
- Application logs (记录业务相关事件)
- System logs (记录操作系统级信息)
📊 Example:
[2023-10-05 14:30:00] INFO: User accessed /en/guides/server_logs
[2023-10-05 14:31:22] ERROR: 500 Internal Server Error at /api/data
🛠️ Configuring Server Logs
To configure logs, modify your server's settings:
- Set log levels (e.g.,
INFO,DEBUG,ERROR) - Define log formats (e.g., JSON, plain text)
- Specify storage locations (e.g.,
/var/log/myapp/) - Enable rotation to prevent disk space issues
🔗 For more details on log rotation, see Log Rotation Best Practices.
📊 Analyzing Server Logs
Use tools like tail, grep, or ELK Stack (Elasticsearch, Logstash, Kibana) to analyze logs:
- Search for errors:
grep "ERROR" /var/log/myapp/error.log - Monitor real-time:
tail -f /var/log/myapp/access.log - Visualize data: Kibana Dashboard

📌 Tips for Effective Logging
- Log only necessary information to avoid noise
- Use consistent timestamps and formats
- Encrypt sensitive data in logs (e.g., passwords)
- Automate alerts for critical errors
If you're using Nginx, check its logging documentation for advanced configurations.
