Understanding Logs

Envloom maintains detailed logs for all runtime operations. This guide explains where logs are located and how to use them for troubleshooting.

Log Directory Structure

All logs are centralized in the logs directory at the same level as bin, config, and sites:

Envloom/
├── bin/
├── config/
├── sites/
└── logs/
    ├── runtime.log
    ├── php/
    │   ├── php-8_3.error.log
    │   ├── php-8_2.error.log
    │   └── php-8_1.error.log
    ├── nginx/
    │   ├── access.log
    │   ├── error.log
    │   └── sites/
    │       ├── mysite.test.access.log
    │       ├── mysite.test.error.log
    │       ├── another.test.access.log
    │       └── another.test.error.log
    └── mariadb/
        ├── mariadb.error.log
        ├── mariadb.general.log
        └── mariadb.slow.log

Runtime Logs

runtime.log

Location: logs/runtime.log Purpose: Main Envloom application log tracking runtime operations, service management, and system events. Format:

[2026-03-08 14:23:15] [INFO] [bootstrap] Starting PHP download
[2026-03-08 14:23:45] [INFO] [php] Installed PHP 8.3.2
[2026-03-08 14:24:01] [ERROR] [nginx] Failed to start: port 80 already in use
[2026-03-08 14:25:10] [INFO] [nvm] Installing Node.js 20.11.0

What it contains:

Service start/stop operations
Runtime installations and updates
NVM operations (nvm install, nvm use)
Configuration changes
System-level errors

When to check:

Services fail to start or stop
Runtime installations fail
General troubleshooting of Envloom behavior

The runtime log uses timestamp format YYYY-MM-DD HH:MM:SS with levels: INFO, WARN, ERROR.

PHP Logs

PHP Error Logs (per version)

Location: logs/php/php-{version}.error.log Examples:

logs/php/php-8_3.error.log
logs/php/php-8_2.error.log
logs/php/php-8_1.error.log

Purpose: PHP runtime errors, warnings, and notices for each installed PHP version. Configuration: Automatically configured via php.ini:

; --- Envloom runtime logging ---
log_errors = On
error_log = "/path/to/logs/php/php-8_3.error.log"
; --- /Envloom runtime logging ---

What it contains:

[08-Mar-2026 14:30:22 UTC] PHP Warning: Undefined variable $foo in /path/to/site/index.php on line 42
[08-Mar-2026 14:31:15 UTC] PHP Fatal error: Uncaught Error: Call to undefined function missing_func()
[08-Mar-2026 14:32:01 UTC] PHP Parse error: syntax error, unexpected ';' in /path/to/file.php on line 10

When to check:

Application shows white screen or 500 error
PHP warnings or notices in development
Fatal errors during site provisioning
Debugging Laravel/Symfony applications

Each PHP version has its own log file. Make sure to check the log for the version your site is using.

Viewing PHP Logs in Envloom

Open Envloom application
Navigate to Logs page
Select PHP tab
Choose version (“current” or specific version)
Logs are displayed with syntax highlighting

Nginx Logs

Global Nginx Logs

Location: logs/nginx/

127.0.0.1 - - [08/Mar/2026:14:35:22 +0000] "GET /index.php HTTP/1.1" 200 1234 "-" "Mozilla/5.0"

Purpose:

access.log: All HTTP requests across all sites
error.log: Nginx-level errors (upstream connections, file access, configuration errors)

Per-Site Nginx Logs

Location: logs/nginx/sites/{domain}.{access|error}.log Examples:

logs/nginx/sites/mysite.test.access.log
logs/nginx/sites/mysite.test.error.log

Purpose: HTTP requests and errors specific to each site. Access Log Format (per request):

IP - - [Date] "Method Path Protocol" StatusCode Bytes "Referer" "UserAgent"

Common Error Types:

# PHP-FPM connection failed
[error] connect() failed (10061: No connection could be made) while connecting to upstream, upstream: "fastcgi://127.0.0.1:9000"

# File not found (404)
[error] open() "/path/to/mysite/public/missing.jpg" failed (2: No such file or directory)

# Permission denied
[crit] open() "/path/to/mysite/public/file.php" failed (13: Permission denied)

When to check:

502 Bad Gateway errors (PHP-FPM not responding)
404 errors (file not found)
Slow site performance (check access log timestamps)
SSL/HTTPS issues

Viewing Nginx Logs in Envloom

Open Logs page
Select Nginx tab
Choose:
- General: Global access and error logs
- Site-specific: Logs for a particular domain
Access log is shown on top, error log below

Nginx logs use standard Nginx log format. The access log can become large; consider rotating logs periodically.

MariaDB Logs

MariaDB Error Log

Location: logs/mariadb/mariadb.error.log Purpose: Database server errors, warnings, and startup messages. What it contains:

2026-03-08 14:40:00 0 [Note] Server socket created on IP: '127.0.0.1'.
2026-03-08 14:40:01 0 [Note] mariadbd: ready for connections.
2026-03-08 14:41:15 8 [Warning] Aborted connection 8 to db: 'mydb' user: 'root' host: 'localhost'
2026-03-08 14:42:30 0 [ERROR] Can't start server: Bind on TCP/IP port: Address already in use

When to check:

2026-03-08 14:45:12    12 Query     UPDATE users SET name = 'John' WHERE id = 1
2026-03-08 14:45:13    12 Quit

When to check:

Debugging query issues
Performance analysis
Understanding what queries Laravel/Symfony is running

The general log can grow very large in active development. Consider disabling it if performance becomes an issue.

MariaDB Slow Query Log

Location: logs/mariadb/mariadb.slow.log Purpose: Queries that take longer than the configured threshold (slow query log is enabled by default). What it contains:

# Time: 2026-03-08T14:50:15.123456Z

SELECT * FROM large_table WHERE unindexed_column LIKE '%search%';

When to check:

Site performance issues
Identifying unoptimized queries
Database tuning

Viewing MariaDB Logs in Envloom

Open Logs page
Select MySQL tab (MariaDB logs)
View error, general, or slow query logs

Log Configuration

PHP Logging Configuration

PHP logs are automatically configured when PHP is installed. The configuration is injected into each version’s php.ini:

; --- Envloom runtime logging ---
log_errors = On
error_log = "/path/to/envloom/logs/php/php-8_3.error.log"
; --- /Envloom runtime logging ---

Customize logging in config/php.ini (base template) or config/php/{version}.ini (version-specific overrides).

MariaDB Logging Configuration

MariaDB logs are configured in config/mariadb/my.cnf:

[mariadb]
log_error=/path/to/envloom/logs/mariadb/mariadb.error.log
general_log=1
general_log_file=/path/to/envloom/logs/mariadb/mariadb.general.log
slow_query_log=1
slow_query_log_file=/path/to/envloom/logs/mariadb/mariadb.slow.log

Disable general log (for performance) by editing my.cnf:

general_log=0

Nginx Logging Configuration

Nginx logs are automatically configured by Envloom when sites are created. Configuration is in:

Global: bin/nginx/current/conf/nginx.conf
Per-site: sites/{domain}.conf

Accessing Logs Quickly

From Envloom UI

Logs Page: Navigate to Logs in the sidebar
Auto-refresh: Click refresh button to reload logs
Syntax Highlighting: Logs are displayed with color-coded highlighting using @melloware/react-logviewer

From System Tray

Right-click Envloom tray icon
PHP submenu > Logs
Nginx submenu > Access Log or Error Log

From File Explorer

Locate Envloom Directory

By default, Envloom stores logs relative to the executable.Development: src-tauri/logs/Production: {Envloom Directory}/logs/

Navigate to Log Type

Choose the appropriate subdirectory (php, nginx, mariadb).

Open Log File

Use your favorite text editor or log viewer. Recommended tools:

Notepad++
VS Code
Tail for Windows
BareTail

Log Rotation and Maintenance

Envloom does not automatically rotate logs. Large log files can impact performance.

Manual log cleanup:

# Navigate to logs directory
cd C:\Path\To\Envloom\logs

# Clear all logs
Get-ChildItem -Recurse -Filter *.log | Clear-Content

# Or delete and recreate
Get-ChildItem -Recurse -Filter *.log | Remove-Item

Recommended: Set up Windows Task Scheduler to periodically clear old logs.
