Logs

What are Logs?

Logs let you view your project's runtime logs and access logs. Use them for error troubleshooting, verifying application behavior, and security monitoring.

Key Features

• Two types of logs: Runtime logs and Access logs
• Flexible time ranges: From 10 minutes to 1 day, or custom ranges
• Environment filters: Switch between Production and Preview environments
• Real-time monitoring: View the latest logs immediately

Tips & FAQ

Q: How long are logs retained?

A: Log retention period may vary depending on your plan. Please contact support for details.

Q: Can I download logs?

A: The current screen does not have a direct download feature. If needed, you can copy and paste logs, or consider using an external log management tool.

Q: Can I monitor logs in real-time?

A: With the screen open, you can achieve near real-time monitoring by setting the time range to a short duration like "10m" and refreshing periodically.

Q: There are too many error logs and it's hard to read

A:

• Set a shorter time range (10m, 30m)
• Use the search function to filter error messages
• Switch between environments to check Production/Preview separately

Q: No logs are displayed

A: Please check the following:

• Is the correct environment (Production/Preview) selected?
• Is the time range appropriate (is the application active during that time)?
• Has the deployment completed successfully?

Basic Error Investigation Steps

Recommended Usage

1. Post-deployment verification: Always check logs immediately after a new deployment to ensure there are no errors
2. Regular monitoring: For critical applications, make it a habit to check logs regularly
3. Immediate verification when issues occur: When users report problems, check the Logs tab right away
4. Check by environment: When testing in Preview environment, also check logs to ensure there are no issues
