+Key Metrics to Monitor
+----------------------
+
+4G Networks
+^^^^^^^^^^^
+
+When troubleshooting 4G connectivity issues, monitor the following:
+
+- **eNB Status**: Check if the eNodeB is properly connected and registered
+- **Subscriber Information**: Verify IP address allocation and IMSI registration
+- **Bearer Status**: Ensure default and dedicated bearers are established correctly
+- **S1-AP Connection**: Verify the control plane connection between eNB and MME
+- **S1-U Connection**: Check the user plane connection between eNB and SGW/PGW
+
+5G Networks
+^^^^^^^^^^^
+
+When troubleshooting 5G connectivity issues, monitor the following:
+
+- **gNB Status**: Check if the gNodeB is properly connected and registered
+- **Subscriber Information**: Verify IP address allocation and IMSI/SUPI registration
+- **PDU Session Status**: Ensure PDU sessions are established correctly
+- **NG-AP Connection**: Verify the control plane connection between gNB and AMF
+- **N3 Connection**: Check the user plane connection between gNB and UPF
+
+Common Troubleshooting Steps
+----------------------------
+
+1. **Verify Pod Status**: Ensure all SD-Core pods are running without errors
+2. **Check Logs**: Review logs from relevant network functions (AMF, SMF, UPF, etc.)
+3. **Validate Configuration**: Confirm subscriber, device group, and network slice configurations
+4. **Network Connectivity**: Test connectivity between components
+5. **Resource Availability**: Check CPU, memory, and network resources
