+# Docker Setup for PHP APM with Elasticsearch
+
+Complete Docker environment for testing PHP APM extension with Elasticsearch driver.
+
+## 🚀 Quick Start
+
+### 1. Build and Start Containers
+
+```bash
+cd /Users/AnyKey/Projects/php-apm
+
+# Build and start all services
+docker-compose up -d
+
+# View logs
+docker-compose logs -f
+```
+
+### 2. Wait for Services to Start
+
+The services will be available at:
+- **PHP Application**: http://localhost:8080
+- **Elasticsearch**: http://localhost:9200
+- **Kibana**: http://localhost:5601
+
+Wait about 30 seconds for Elasticsearch and Kibana to fully start.
+
+### 3. Test APM
+
+Open http://localhost:8080 in your browser and click "Run Test" to generate sample events.
+
+## 📦 What's Included
+
+### Services
+
+1. **php-app** (PHP 5.6 with APM Extension)
+   - Apache web server
+   - APM extension with Elasticsearch driver enabled
+   - Pre-configured to send data to Elasticsearch
+   - Batch sending enabled (10 docs or 5 seconds)
+
+2. **elasticsearch** (Elasticsearch 7.17.10)
+   - Single-node cluster
+   - No security (for testing only)
+   - Stores APM events and statistics
+
+3. **kibana** (Kibana 7.17.10)
+   - Web UI for Elasticsearch
+   - Visualize APM data
+   - Create dashboards
+
+### Configuration
+
+APM is pre-configured with:
+```ini
+apm.enabled=On
+apm.elasticsearch_enabled=On
+apm.elasticsearch_host=elasticsearch
+apm.elasticsearch_port=9200
+apm.elasticsearch_index=apm-logs
+apm.elasticsearch_batch_size=10
+apm.elasticsearch_batch_timeout=5
+```
+
+## 🔍 Verifying Installation
+
+### Check APM Extension
+
+```bash
+docker-compose exec php-app php -m | grep apm
+```
+
+Expected output: `apm`
+
+### Check APM Configuration
+
+```bash
+docker-compose exec php-app php -i | grep elasticsearch
+```
+
+### Check Elasticsearch Connection
+
+```bash
+curl http://localhost:9200/_cat/health?v
+```
+
+## 📊 Viewing Data
+
+### Via Command Line
+
+```bash
+# View all APM documents
+curl http://localhost:9200/apm-logs/_search?pretty
+
+# Count documents
+curl http://localhost:9200/apm-logs/_count
+
+# View index info
+curl http://localhost:9200/_cat/indices?v | grep apm
+```
+
+### Via Kibana
+
+1. Open http://localhost:5601
+2. Go to **Management** → **Stack Management** → **Index Patterns**
+3. Create index pattern: `apm-logs*`
+4. Go to **Discover** to view documents
+5. Create visualizations and dashboards
+
+## 🛠️ Docker Commands
+
+### Start Services
+
+```bash
+docker-compose up -d
+```
+
+### Stop Services
+
+```bash
+docker-compose down
+```
+
+### Stop and Remove Data
+
+```bash
+docker-compose down -v
+```
+
+### Rebuild PHP Container
+
+```bash
+docker-compose build --no-cache php-app
+docker-compose up -d php-app
+```
+
+### View Logs
+
+```bash
+# All services
+docker-compose logs -f
+
+# Specific service
+docker-compose logs -f php-app
+docker-compose logs -f elasticsearch
+```
+
+### Execute Commands in Container
+
+```bash
+# PHP shell
+docker-compose exec php-app bash
+
+# Test curl from PHP container
+docker-compose exec php-app curl http://elasticsearch:9200
+```
+
+## 🐛 Troubleshooting
+
+### APM Extension Not Loading
+
+Check build logs:
+```bash
+docker-compose build php-app 2>&1 | tee build.log
+```
+
+Verify extension file exists:
+```bash
+docker-compose exec php-app ls -l /usr/local/lib/php/extensions/
+```
+
+### No Data in Elasticsearch
+
+1. Check if APM can reach Elasticsearch:
+```bash
+docker-compose exec php-app ping -c 3 elasticsearch
+docker-compose exec php-app curl -v http://elasticsearch:9200
+```
+
+2. Check APM debug output (if compiled with `--with-debugfile`):
+```bash
+docker-compose exec php-app tail -f /tmp/apm.debug
+```
+
+3. Verify PHP errors are being triggered:
+```bash
+docker-compose exec php-app php -r "trigger_error('Test', E_USER_WARNING);"
+```
+
+### Elasticsearch Won't Start
+
+Check memory limits:
+```bash
+docker stats
+```
+
+Elasticsearch needs at least 512MB RAM. Adjust in `docker-compose.yml` if needed.
+
+### Port Already in Use
+
+If ports are already taken, edit `docker-compose.yml`:
+```yaml
+ports:
+  - "8081:80"  # Change 8080 to 8081
+```
+
+## 📈 Performance Tuning
+
+### Batch Size
+
+Larger batches = fewer HTTP requests but higher latency:
+```ini
+apm.elasticsearch_batch_size=50
+```
+
+### Batch Timeout
+
+Shorter timeout = more real-time but more requests:
+```ini
+apm.elasticsearch_batch_timeout=1
+```
+
+### Disable Unused Features
+
+```ini
+apm.store_stacktrace=Off
+apm.store_cookies=Off
+apm.store_post=Off
+```
+
+## 🔐 Production Considerations
+
+This setup is for **testing only**. For production:
+
+1. Enable Elasticsearch security:
+```yaml
+environment:
+  - xpack.security.enabled=true
+  - ELASTIC_PASSWORD=changeme
+```
+
+2. Use strong passwords
+3. Enable HTTPS
+4. Restrict network access
+5. Use proper resource limits
+6. Enable authentication in APM config
+
+## 📝 Example PHP Test Script
+
+Create `test/custom-test.php`:
+```php
+<?php
+// Generate some load
+for ($i = 0; $i < 1000; $i++) {
+    $data[] = md5(rand());
+}
+sleep(1);
+
+// Trigger errors
+trigger_error("Custom test warning", E_USER_WARNING);
+trigger_error("Custom test notice", E_USER_NOTICE);
+
+echo "Test completed! Check Elasticsearch for logs.\n";
+?>
+```
+
+Run it:
+```bash
+docker-compose exec php-app php /var/www/html/custom-test.php
+```
+
+## 🎓 Next Steps
+
+1. **Create Kibana Dashboards**
+   - Visualize error rates
+   - Monitor response times
+   - Track memory usage
+
+2. **Set Up Alerts**
+   - Alert on error spikes
+   - Monitor slow requests
+   - Track resource usage
+
+3. **Optimize Configuration**
+   - Tune batch settings
+   - Adjust thresholds
+   - Enable/disable features
+
+4. **Test in Production-Like Environment**
+   - Add load testing
+   - Test with realistic data
+   - Monitor performance impact
