FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Informations about the package module-log-viewer
Fsm_LogViewer
Admin Log Viewer for Magento Open Source / Mage-OS. Lists and displays files under var/log with per-role glob patterns and optional download permission.
Features
- Grid of log files allowed for the current admin role
- Tail view (last 512 KB) with in-page search
- Download gated by ACL and role flag
- Role tab under System → Permissions → User Roles to configure patterns
Requirements
- PHP 8.2+
- Magento Open Source / Mage-OS 2.4+ (compatible with Magento Backend, User, Authorization, UI)
Installation
Composer (recommended for distribution)
App code
Copy this module to app/code/Fsm/LogViewer, then run the same module:enable / setup:upgrade commands.
Configuration
- Open System → Permissions → User Roles.
- Edit a role → Log Viewer tab.
-
Enter one glob pattern per line (basename under
var/log), for example: - Optionally enable Allow Download.
- Assign ACL resources under System → Tools → Log Viewer:
- View Logs — list and open files
- Download Logs — download (also requires the role flag)
Empty patterns mean the role sees no log files.
The Size column filter uses bytes (display is human-readable).
Security
Log files often contain personal data, stack traces, tokens, or other secrets.
- Prefer specific patterns (
system.log,exception.log) over*.log. - Grant Download only to roles that need full files.
- The module rejects path traversal, null bytes, and symlinks under
var/log. - Viewing still exposes file contents to anyone with View ACL and matching patterns — treat role setup as a security control.
To report vulnerabilities, see SECURITY.md.
