Log Files – View and Export MideyeServer System Logs

Overview

The Log Files page provides a web-based log viewer for MideyeServer's system log files. Administrators can select from available log files, view their contents in real-time with auto-scrolling, search for specific entries, and export log files for offline analysis or sharing with support teams.

This page eliminates the need for direct server access to review logs. The viewer supports real-time tailing (follow mode), case-insensitive search, and selectable lines — making it an effective tool for live troubleshooting, post-incident analysis, and diagnostic data collection.

Note

This page does not use a data grid. It renders log file contents in a specialized log viewer component optimized for large text files.

Features & Configuration

Selecting a Log File

A dropdown selector at the top of the page lists all available log files on the server. By default, mideyeserver.log is selected — this is the primary application log file.

Other log files may include rotated logs (e.g., mideyeserver.log.1, mideyeserver.log.2.gz), trace logs, and error-specific log files depending on the server configuration.

Log Viewer

The log viewer renders the selected file's content in a scrollable, formatted display that fills the available viewport height. Key features:

| Feature | Description | |---------|-------------| | Follow mode | Auto-scrolls to the bottom as new log entries are written. Useful for live monitoring. | | Search | Built-in search bar for finding specific text within the log file. Case-insensitive. | | Line selection | Click on individual log lines to highlight and select them. | | Responsive height | The viewer adjusts to fill the available viewport (calc(100vh - 250px)). |

The log content is fetched via an authenticated API call using the current user's JWT token, ensuring secure access to sensitive log data.

Exporting Log Files

Click the Export (download) icon button next to the log file selector to download the currently selected log file.

Export Dialog:

• Confirmation message: "Are you sure you want to export log file with name: [filename]?"
• On confirmation, the file is downloaded as a binary blob to the browser.

The exported file retains its original filename and format.
