+
+**Key Points:**

+- Production and test processes run **simultaneously** with distinct names

+- Test processes use Redis database 1 (isolated from production which uses database 0)
+- Both configs validate required environment variables but only warn (don't exit) if missing

-### Step 2: Configure Application to Write File Logs
+### Step 2: Application File Logging (Already Configured)
 
-The flyer-crawler application uses Pino for logging and currently outputs to stdout (captured by PM2). To enable file-based logging for Logstash, you would need to configure Pino to write to files.
+The flyer-crawler application uses Pino for logging and is configured to write logs to files in production/test environments:
 
-**Current Behavior:** Logs go to stdout → PM2 captures them → `~/.pm2/logs/`
+**Log File Locations:**
 
-**For Logstash Integration:** You would need to either:
+| Environment   | Log File Path                                             |
+| ------------- | --------------------------------------------------------- |
+| Production    | `/var/www/flyer-crawler.projectium.com/logs/app.log`      |
+| Test          | `/var/www/flyer-crawler-test.projectium.com/logs/app.log` |
+| Dev Container | `/app/logs/app.log`                                       |
 
-1. Configure Pino to write directly to files (requires code changes)
-2. Use PM2's log files instead (located at `~/.pm2/logs/flyer-crawler-*.log`)
+**How It Works:**
 
-For now, we'll use PM2's log files which already exist:
+- In production/test: Pino writes JSON logs to both stdout (for PM2) AND `logs/app.log` (for Logstash)
+- In development: Pino uses pino-pretty for human-readable console output only
+- The log directory is created automatically if it doesn't exist
+- You can override the log directory with the `LOG_DIR` environment variable
+
+**Verify Logging After Deployment:**
+
+After deploying the application, verify that logs are being written:
 
 ```bash
-# Check PM2 log location
-ls -la ~/.pm2/logs/
+# Check production logs
+ls -la /var/www/flyer-crawler.projectium.com/logs/
+tail -f /var/www/flyer-crawler.projectium.com/logs/app.log
+
+# Check test logs
+ls -la /var/www/flyer-crawler-test.projectium.com/logs/
+tail -f /var/www/flyer-crawler-test.projectium.com/logs/app.log
+```
+
+You should see JSON-formatted log entries like:
+
+```json
+{ "level": 30, "time": 1704067200000, "msg": "Server started on port 3001", "module": "server" }

+Logstash runs as the `logstash` user and needs permission to read log files:
 
 ```bash
-# Add logstash user to the group that owns PM2 logs
-# If PM2 runs as root:
-sudo usermod -a -G root logstash
+# Add logstash user to adm group (for nginx and redis logs)
+sudo usermod -aG adm logstash
 
-# Or, make PM2 logs world-readable (less secure but simpler)
-sudo chmod 644 /root/.pm2/logs/*.log
+# Make application log files readable (created automatically when app starts)
+sudo chmod 644 /var/www/flyer-crawler.projectium.com/logs/app.log 2>/dev/null || echo "Production log file not yet created"
+sudo chmod 644 /var/www/flyer-crawler-test.projectium.com/logs/app.log 2>/dev/null || echo "Test log file not yet created"
 
-# For Redis logs
+# Make Redis logs and directory readable
+sudo chmod 755 /var/log/redis/
 sudo chmod 644 /var/log/redis/redis-server.log
+
+# Make NGINX logs readable
+sudo chmod 644 /var/log/nginx/access.log /var/log/nginx/error.log
+
+# Make PM2 logs and directories accessible
+sudo chmod 755 /home/gitea-runner/
+sudo chmod 755 /home/gitea-runner/.pm2/
+sudo chmod 755 /home/gitea-runner/.pm2/logs/
+sudo chmod 644 /home/gitea-runner/.pm2/logs/*.log
+
+# Verify logstash group membership
+groups logstash
 ```
 
-**Note:** If PM2 runs as a different user, adjust the group accordingly.
+**Note:** The application log files are created automatically when the application starts. Run the chmod commands after the first deployment.
