Chapter 9. Troubleshooting Red Hat Edge Manager
When working with devices in Red Hat Edge Manager, you might see issues related to configuration, connectivity, or deployment. Troubleshooting these issues requires understanding how device configurations are applied, how to check logs, and how to verify communication between the device and the service.
9.1. Viewing a device’s effective target configuration
The device manifest returned by the flightctl get device command still only has references to external configuration and secret objects. Only when the device agent queries the service, the service replaces the references with the actual configuration and secret data. While this better protects potentially sensitive data, it also makes troubleshooting faulty configurations hard. This is why a user can be authorized to query the effective configuration as rendered by the service to the agent.
Procedure
To query the effective configuration, use the following command:
flightctl get device/${device_name} --rendered | jqflightctl get device/${device_name} --rendered | jqCopy to Clipboard Copied! Toggle word wrap Toggle overflow
9.2. Generating a device log bundle
The device includes a script that generates a bundle of logs necessary to debug the agent.
Procedure
Run the following command on the device and include the .tar file in the bug report.
NoteThis depends on an SSH connection to extract the .tar file.
sudo flightctl-must-gather
sudo flightctl-must-gatherCopy to Clipboard Copied! Toggle word wrap Toggle overflow
