### Troubleshooting
Connect to JumpVM as described [above](#vtfiexk944z) and check these log files:
* Main handler log:
{% code overflow="wrap" %}
```
cat /var/log/azure/custom-script/handler.log
```
{% endcode %}
This is the primary log file for the Azure VM extension that runs custom scripts during deployment. It records overall extension execution status, including when scripts start and finish, and any high-level errors.
* Deployment stdout/stderr:
cat /var/lib/waagent/custom-script/download/0/stdout
cat /var/lib/waagent/custom-script/download/0/stderr
\
These files contain the actual console output from the deployment scripts:
1. `stdout` shows the normal output of commands that ran successfully
2. `stderr` captures error messages and warnings from failed commands
These logs provide detailed information about what specific commands were executed and their results during the initial setup process.
* Terraform and AKS deployment logs:
```
cat /root/lightbeam/lightbeam-tf-iac/aks/terraform_apply.log
```
This log specifically focuses on the infrastructure deployment stage using Terraform. It shows:
1. AKS (Azure Kubernetes Service) cluster creation
2. Node pool configuration and deployment
* LightBeam application deployment logs:
```
cat /root/lightbeam/lightbeam-chart/lightbeam_install.log
```
This final log shows the deployment of the actual LightBeam application into the Kubernetes cluster.
### Uninstallation
1. Connect to JumpVM and switch to root:
```
sudo su
```
2. Clean up LightBeam cluster:
```
cd /root/lightbeam/lightbeam-chart
./installer/lb-cleanup.sh
```
3. Remove AKS infrastructure:
```
cd /root/lightbeam/lightbeam-tf-iac/aks
terraform destroy
```
Type "yes" when prompted and wait for completion
4. Complete cleanup:
* Delete all resources from the Azure Resource Group
* Network Security Group,Network Interface, Jump VM Public IP, VNET, Subnet, JumpVM etc.
* Remove JumpVM role assignments (Network Contributor and AKS Service Contributor)
