 **Issue**: Potential insecure TLS configuration with minimal validation
 
 **Risks**:
+
 - Lack of explicit cipher suite configuration
 - No clear TLS version constraints
 - Potential use of weak certificates
 
 **Suggested Fix**:
+
 - Implement strict TLS configuration
 - Enforce TLS 1.2 or 1.3
 - Use strong cipher suites
 - Implement certificate rotation mechanisms
 
 ### 2. HTTP Client Security

 **Issue**: Potential HTTP client configuration vulnerabilities
 
 **Risks**:

 - No explicit timeout configurations
 - Potential for connection leaks
 - Lack of connection pooling strategies
 
 **Suggested Fix**:

 - Implement default and configurable timeouts
 - Use context-based request cancellation
 - Configure connection pooling

 ## Code Quality
 
 ### 1. Modular Design
+
 **Strengths**:
+
 - Clear separation of concerns
 - Distinct structs for NGINX clients and metric collectors
 - Flexible configuration options
 
 **Recommendations**:
+
 - Continue maintaining architectural boundaries
 - Add comprehensive interface documentation
 - Implement more extensive unit testing
 
 ## Observability
 
 ### 1. Logging and Tracing
+
 **Current State**:
+
 - Basic logging mechanisms
 - Limited internal health metrics
 
 **Recommendations**:
+
 - Enhance error logging
 - Implement detailed tracing for metric collection
 - Add comprehensive health check endpoints
