Best Practices for Debug Logging in Syncloop APIs

Why Debug Logging Matters

• Issue Identification:
  • Tracks the execution flow to pinpoint errors and bottlenecks.
• Improved Debugging:
  • Provides detailed context about system behavior during failures.
• Operational Transparency:
  • Logs serve as a record for analyzing how APIs handle requests.
• Compliance and Auditing:
  • Maintains records for security and regulatory purposes.
• Performance Optimization:
  • Highlights inefficiencies and areas for improvement.

Key Features of Debug Logging in Syncloop

1. Granular Log Levels

• What It Does:
  • Supports log levels like DEBUG, INFO, WARN, and ERROR.
• Benefit:
  • Allows selective logging based on the environment or use case.

2. Real-Time Log Monitoring

• What It Does:
  • Displays live logs during API execution.
• Benefit:
  • Facilitates immediate troubleshooting during testing or production.

3. Customizable Logging

• What It Does:
  • Lets developers define what information to log.
• Benefit:
  • Reduces log noise and focuses on relevant data.

4. Secure Logging

• What It Does:
  • Masks sensitive data to protect user privacy and meet compliance standards.
• Benefit:
  • Ensures security while maintaining log detail.

5. Log Retention and Storage

• What It Does:
  • Configures retention policies and integrates with external storage solutions.
• Benefit:
  • Balances storage costs and regulatory requirements.

Steps to Implement Debug Logging in Syncloop

Step 1: Configure Log Levels

• Action:
  • Define the appropriate log level for your API (e.g., DEBUG for development, INFO for production).
• How-To:
  • Use the Syncloop dashboard to set log levels for individual APIs or workflows.

Step 2: Enable Debug Logging

• Action:
  • Activate debug logging for detailed tracking of API operations.
• How-To:
  • Navigate to the “Logging” section in Syncloop and toggle DEBUG mode.

Step 3: Define Logging Scope

• Action:
  • Specify which parts of the API workflow to log (e.g., request headers, payloads, execution time).
• How-To:
  • Use Syncloop’s customization options to tailor logging to your needs.

Step 4: Mask Sensitive Data

• Action:
  • Protect sensitive information in logs.
• How-To:
  • Configure masking rules for fields like passwords, tokens, or financial data.

Step 5: Monitor Logs in Real Time

• Action:
  • Use Syncloop’s live log viewer to analyze API behavior during execution.
• Use Case:
  • Identify and fix misconfigurations or errors during testing.

Step 6: Store and Archive Logs

• Action:
  • Set up storage and retention policies.
• How-To:
  • Integrate Syncloop logs with external systems like AWS S3 or Splunk for long-term storage.

Step 7: Review and Optimize

• Action:
  • Periodically analyze logs to identify recurring issues or performance bottlenecks.
• Use Case:
  • Use insights to refine API workflows and improve efficiency.

Best Practices for Debug Logging

• Use Granular Log Levels:
  • Employ DEBUG logs in development and INFO or WARN in production.
• Avoid Logging Sensitive Data:
  • Always mask or exclude personal and sensitive information from logs.
• Limit Log Volume:
  • Focus on actionable details to prevent log overload.
• Enable Conditional Logging:
  • Log specific workflows or endpoints based on conditions or triggers.
• Monitor Log Health:
  • Regularly review logs to ensure they are accurate and useful.
• Integrate with Analytics Tools:
  • Use tools like ELK Stack or Datadog for advanced log analysis.
