# System Debugging

The system debugging page supports real-time debugging functionality. When enabled, it records logs from various system modules for developers to use in problem diagnosis.

## Types and Levels of Debug Logs

During system debugging, logs related to the following modules are recorded, including:

* Global Logs
* Metadata Database Operation Logs
* Scheduled Task Logs
* Request Filter Logs
* User Authentication Component Logs
* Database Connection Pool Logs

Each type of log can be set to one of five levels: INFO, WARN, ERROR, DEBUG, TRACE. These levels are suitable for different debugging scenarios and support unified settings across all modules. DEBUG logs can be configured with a unified shutdown time.

## Enable APM Logs

Monitor system performance and health status to identify performance bottlenecks, abnormal trends, and user experience issues. Once enabled, you can set an automatic shutdown time.

## Real-time Debugging

When the real-time debugging switch is turned on, the system starts recording debugging-related logs. The top of the page displays the start time and duration of debugging. Once the operation is complete, you can click **Export** to download the logs locally. After exporting, you can click **Exit** to close real-time debugging.

> \[!TIP] Tip
>
> 1. When the real-time debugging switch is turned on, the system starts recording logs immediately. Therefore, please set the log levels properly before enabling it.
> 2. If you close real-time debugging without exporting the logs during the operation, you can export them from the historical logs.

## Export Server-Side Historical Logs

The system supports exporting historical debugging information. Click the calendar icon to select the start date and end date, then click **Export** to download the debugging logs for the selected date range. If the real-time debugging feature was not enabled during the selected date range, the system will display a prompt message.
