+# OpenTelemetry V2.8 Improvements Example
+
+This example demonstrates the new configurable OpenTelemetry tracing features for SQL, HTTP requests, and HTTP responses.
+
+**Updated to OpenTelemetry v1.38.0 with Independent OTEL Parameters**
+
+## HTTP Server Configuration
+
+### New Independent OTEL Configuration (Recommended)
+```yaml
+server:
+  address: ":8080"
+  otel:
+    traceRequestEnabled: true   # Enable HTTP request parameter tracing
+    traceResponseEnabled: true  # Enable HTTP response body tracing
+```
+
+### Legacy Configuration (Still Supported)
+```yaml
+server:
+  address: ":8080"
+  otelTraceRequestEnabled: true   # Enable HTTP request parameter tracing  
+  otelTraceResponseEnabled: true  # Enable HTTP response body tracing
+```
+
+## Database Configuration
+
+### New Independent OTEL Configuration (Recommended)
+```yaml
+database:
+  default:
+    type: "mysql"
+    host: "127.0.0.1"
+    port: "3306"
+    user: "your_user"
+    pass: "your_password"
+    name: "your_database"
+    otel:
+      traceSQLEnabled: true  # Enable SQL statement tracing
+```
+
+### Legacy Configuration (Still Supported)
+```yaml
+database:
+  default:
+    type: "mysql"
+    host: "127.0.0.1"
+    port: "3306"
+    user: "your_user"
+    pass: "your_password"
+    name: "your_database"
+    otelTraceSQLEnabled: true  # Enable SQL statement tracing
+```
+
+## Programmatic Configuration
+
+### HTTP Server - New Independent OTEL Configuration
+```go
+package main
+
+import (
+    "github.com/gogf/gf/v2/frame/g"
+    "github.com/gogf/gf/v2/internal/otel"
+    "github.com/gogf/gf/v2/net/ghttp"
+)
+
+func main() {
+    s := g.Server()
+
+    // Configure using new independent OTEL configuration
+    config := ghttp.NewConfig()
+    config.Address = ":8080"
+    config.Otel = otel.Config{
+        TraceRequestEnabled:  true,
+        TraceResponseEnabled: true,
+    }
+    s.SetConfig(config)
+
+    s.BindHandler("/api/test", func(r *ghttp.Request) {
+        // This handler will have its request parameters and response traced
+        r.Response.WriteJson(g.Map{
+            "message": "Hello World",
+            "input":   r.Get("input"),
+        })
+    })
+
+    s.Run()
+}
+```
+
+### HTTP Server - Legacy Configuration (Still Supported)
+```go
+package main
+
+import (
+    "github.com/gogf/gf/v2/frame/g"
+    "github.com/gogf/gf/v2/net/ghttp"
+)
+
+func main() {
+    s := g.Server()
+
+    // Enable tracing via configuration map (legacy approach)
+    s.SetConfigWithMap(g.Map{
+        "OtelTraceRequestEnabled":  true,
+        "OtelTraceResponseEnabled": true,
+    })
+
+    s.BindHandler("/api/test", func(r *ghttp.Request) {
+        // This handler will have its request parameters and response traced
+        r.Response.WriteJson(g.Map{
+            "message": "Hello World",  
+            "input":   r.Get("input"),
+        })
+    })
+
+    s.Run()
+}
+```
+
+### Database - New Independent OTEL Configuration
+```go
+package main
+
+import (
+    "github.com/gogf/gf/v2/database/gdb" 
+    "github.com/gogf/gf/v2/internal/otel"
+)
+
+func main() {
+    // Configure database with new independent OTEL configuration
+    config := gdb.ConfigNode{
+        Type: "mysql",
+        Host: "127.0.0.1",
+        Port: "3306",
+        User: "your_user",
+        Pass: "your_password",
+        Name: "your_database",
+        Otel: otel.Config{
+            TraceSQLEnabled: true,
+        },
+    }
+
+    db, err := gdb.New(config)
+    if err != nil {
+        panic(err)
+    }
+
+    // SQL statements will now be traced
+    result, err := db.Query("SELECT * FROM users WHERE id = ?", 1)
+    // ... handle result
+}
+```
+
+### Database - Legacy Configuration (Still Supported)  
+```go
+package main
+
+import (
+    "github.com/gogf/gf/v2/database/gdb"
+)
+
+func main() {
+    // Configure database with legacy OTEL configuration
+    config := gdb.ConfigNode{
+        Type: "mysql",
+        Host: "127.0.0.1", 
+        Port: "3306",
+        User: "your_user",
+        Pass: "your_password",
+        Name: "your_database",
+        OtelTraceSQLEnabled: true,  // Legacy field
+    }
+
+    db, err := gdb.New(config)
+    if err != nil {
+        panic(err)
+    }
+
+    // SQL statements will now be traced
+    result, err := db.Query("SELECT * FROM users WHERE id = ?", 1)
+    // ... handle result
+}
+```
+
+## Trace Output Examples
+
+### HTTP Method Tracing
+All HTTP requests now include the HTTP method in traces:
+- `http.method: GET`
+- `http.method: POST`  
+- `http.method: PUT`
+- `http.method: DELETE`
+
+### Request Parameter Tracing (when enabled)
+```json
+{
+  "http.request.params": {
+    "username": "john",
+    "email": "[email protected]",
+    "query_param": "value"
+  }
+}
+```
+
+### Response Body Tracing (when enabled)
+```json
+{
+  "http.response.body": {
+    "code": 200,
+    "message": "Success",
+    "data": {"id": 1, "name": "John Doe"}
+  }
+}
+```
+
+### SQL Tracing (when enabled)
+```json
+{
+  "db.execution.sql": "SELECT * FROM users WHERE id = ? AND status = ?",
+  "db.execution.cost": "15 ms",
+  "db.execution.rows": "1"
+}
+```
+
+## Benefits
+
+1. **OpenTelemetry v1.38.0**: Updated to the latest OpenTelemetry version with improved performance and features
+2. **Independent Configuration**: New modular OTEL configuration structure for better organization
+3. **Configurable**: All new tracing features are opt-in via configuration
+4. **Performance**: Only enabled features add overhead 
+5. **Backward Compatible**: Legacy configuration fields still work alongside new structure  
+6. **Comprehensive**: Covers SQL, HTTP requests, and HTTP responses
+7. **Size Aware**: Respects content size limits to prevent memory issues
+
+## Migration Guide
+
+### From Legacy to New Configuration
+
+#### HTTP Server
+```go
+// Legacy (still works)
+s.SetConfigWithMap(g.Map{
+    "OtelTraceRequestEnabled": true,
+})
+
+// New (recommended)
+config := ghttp.NewConfig()
+config.Otel.TraceRequestEnabled = true
+s.SetConfig(config)
+```
+
+#### Database
+```go
+// Legacy (still works)  
+config := gdb.ConfigNode{
+    OtelTraceSQLEnabled: true,
+}
+
+// New (recommended)
+config := gdb.ConfigNode{
+    Otel: otel.Config{
+        TraceSQLEnabled: true,
+    },
+}
+```
+
+The new configuration provides better organization and allows for future OTEL features to be grouped logically while maintaining full backward compatibility.
