Viewing Log Details

  2. Click in the upper left corner and select a region and a project.
  3. Click in the upper left corner of the page and choose Database > Relational Database Service. The RDS console is displayed.
  4. On the Instance Management page, click the target DB instance.
  5. In the navigation pane on the left, choose Logs. On the Error Logs page, click Log Details to view details about error logs.

    • You can select a log level in the upper right corner of the log list.

      • ERROR
      • FATAL
      • PANIC
    • You can click in the upper right corner to view error logs generated in different time segments.

Download a Log

  1. Log in to the management console.
  2. Click in the upper left corner and select a region and a project.
  3. Click in the upper left corner of the page and choose Database > Relational Database Service. The RDS console is displayed.
  4. On the Instance Management page, click the target DB instance.
  5. In the navigation pane on the left, choose Logs. On the Error Logs page, click Download. In the log list, locate a log whose status is Preparation completed and click Download in the Operation column.

    • The system automatically loads the downloading preparation tasks. The loading duration is determined by the log file size and network environment.
      • When the log is being prepared for download, the log status is Preparing.
      • When the log is ready for download, the log status is Preparation completed.
      • If the preparation for download fails, the log status is Abnormal.

      Logs in the Preparing or Abnormal status cannot be downloaded.

    • If the size of a log to be downloaded is greater than 40 MB, you need to use OBS Browser+ to download it. For details, see Method 1: Using OBS Browser+.
    • The download link is valid for 5 minutes. After the download link expires, a message is displayed indicating that the download link has expired. If you need to download the log, click OK.
