System Logs

System Logs provide real-time insights into system operation status, enabling second-level fault root cause identification to comprehensively enhance system stability and operational efficiency.

Key Features

1. Real-time Monitoring: Instant log viewing for rapid issue response.

2. Fault Diagnosis: Quickly locate system anomalies and performance bottlenecks.

3. Security Auditing: Track operational behaviors to meet compliance requirements.

4. Operational Efficiency: Centralized log management reduces troubleshooting time.

5. Performance Optimization: Analyze logs to optimize system performance.

Application Scenarios

Note

Private deployment versions allow users to modify log levels and print ranges, while cloud service versions do not support viewing system logs.

1. Fault Diagnosis and Troubleshooting

• Scenario: Precise identification of failure points during service exceptions
• Example Case:

  [ERROR] 2025-06-20 19:42:25.539 - DB connection pool exhausted

  👉 Immediately locate database resource bottlenecks, resolved through capacity expansion within 5 minutes

2. Performance Bottleneck Identification

• Scenario: Detect and optimize slow system response issues
• Example Case:

  DEBUG - SELECT...FROM object_file LIMIT ? 
  Execution time: 4.2s

  👉 Identify inefficient SQL queries, improve speed by 300% after adding indexes

3. Service Configuration Validation

• Scenario: Verify configuration effectiveness
• Example Case:

  INFO - Resolved Eureka endpoints: 
  http://192.168.0.70:8080/eureka

  👉 Confirm normal operation of microservice registration and discovery mechanisms

4. Security Event Tracing

• Scenario: Track anomalous operational behaviors
• Example Case:

  WARN - Unauthorized access attempt: 
  user=admin from=10.0.0.155

  👉 Identify malicious IPs and automatically add to blacklist

5. Resource Scheduling Optimization

• Scenario: Monitor resource usage trends
• Example Case:

  DEBUG - ThreadPoolExecutor 80% blocked

  👉 Dynamically adjust thread pool parameters to improve throughput

6. Scheduled Task Monitoring

• Scenario: Ensure timely execution of background tasks
• Example Case:

  INFO - Cleanup task initiated (every 1 hour)
  2025-06-20 10:00:00
  2025-06-20 11:00:00 
  2025-06-20 12:00:00

  👉 Detect missing tasks and trigger immediate alerts

7. Service Start/Stop Verification

• Scenario: Validate service restart effectiveness
• Example Case:

  INFO - StorageService started in 5.3s

  👉 Confirm startup time meets expectations after new version deployment
