    Figure 2 Downloading an error log

    • The system automatically loads the download 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 state cannot be downloaded.

    • Only logs no more than 40 MB can be downloaded directly from this page. The time range is calculated from the time you download the logs back to the time when the accumulated file size reaches 40 MB.
    • The download link is valid for 5 minutes. If the link expires, a message prompts you to download the log again. Click OK to download the log again, or Cancel to cancel the operation
    • You can select the logs to be downloaded by node.
