Troubleshooting

This section aids you in finding problems when working with Constellation.

Cloud logging

To provide information during early stages of the node's boot process, Constellation logs messages into the cloud providers' log systems. Since these offerings aren't confidential, only generic information without any sensitive values are stored. This provides administrators with a high level understanding of the current state of a node.

You can view these information in the follow places:

1. In your Azure subscription find the Constellation resource group.
2. Inside the resource group find the Application Insights resource called constellation-insights-*.
3. On the left-hand side go to Logs, which is located in the section Monitoring.
   • Close the Queries page if it pops up.
4. In the query text field type in traces, and click Run.

To find the disk UUIDs use the following query: traces | where message contains "Disk UUID"

1. Select the project that hosts Constellation.
2. Go to the Compute Engine service.
3. On the right-hand side of a VM entry select More Actions (a stacked ellipsis)
   • Select View logs

To find the disk UUIDs use the following query: resource.type="gce_instance" text_payload=~"Disk UUID:.*\n" logName=~".*/constellation-boot-log"

:::info

Constellation uses the default bucket to store logs. Its default retention period is 30 days.
