 ## Infrastructure Setup
 
 - **App Service Plan (Windows)** - P1v3 tier for high-load testing
-  - See: [./terraform-infrastructure/variables.tf](./terraform-infrastructure/variables.tf) (lines 12-21)
-  - See: [./terraform-infrastructure/main.tf](./terraform-infrastructure/main.tf) (lines 35-45)
-- **Deployment Method**: Standard deployment (extracted .zip)
-  - See: [./terraform-infrastructure/main.tf](./terraform-infrastructure/main.tf) (line 115)
+
+  ```terraform
+  # Service Plan  
+  sku_name            = "P1v3"    
+  ```

+
+- **Deployment Method (Function App Environment Variables)**: Standard deployment (extracted .zip)
+
   ```terraform
   # Force standard deployment instead of mounted package
   "WEBSITE_RUN_FROM_PACKAGE" = "0"
   ```
-- **Application Insights**: Full logging (no sampling)
-  - See: [./terraform-infrastructure/main.tf](./terraform-infrastructure/main.tf) (lines 47-56)

+
+- **Diagnostics Settings (Function App Environment Variables)**: Detailed diagnostics enabled
+
   ```terraform
-  # No sampling configured - full logging
-  sampling_percentage = 100
+  # Enable full diagnostics for troubleshooting
+  "WEBSITE_ENABLE_DETAILED_DIAGNOSTICS" = "true"
   ```
-- **Verbose Diagnostics**: Enabled

+- **Logging Configuration (Function App Environment Variables)**: Verbose logging enabled. Click here to understand more about [log levels types](https://learn.microsoft.com/en-us/azure/azure-functions/configure-monitoring?tabs=v2#configure-log-levels)
+
   ```terraform
-  # Enable full diagnostics

+- **SCM Separation (Function App Environment Variables)**: Enabled to ensure Kudu and function app run as separate processes
+
+  ```terraform
+  # Enable SCM separation for diagnostics
+  "WEBSITE_DISABLE_SCM_SEPARATION" = "false"
   ```
-- **Storage Logging**: Enabled
-  - See: [./terraform-infrastructure/main.tf](./terraform-infrastructure/main.tf) (line 124)

+
+- **Temp Access (Function App Environment Variables)**: Explicitly enabled for diagnostics and reporting
+
   ```terraform
-  # Log to storage account (increases I/O operations)
-  "AzureWebJobsDashboard" = azurerm_storage_account.storage.primary_connection_string
+  # Enable temp file access for diagnostics
