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:
- In your Azure subscription find the Constellation resource group.
- Inside the resource group find the Application Insights resource called
constellation-insights-*
. - On the left-hand side go to
Logs
, which is located in the sectionMonitoring
.- Close the Queries page if it pops up.
- In the query text field type in
traces
, and clickRun
.
To find the disk UUIDs use the following query: traces | where message contains "Disk UUID"
- Select the project that hosts Constellation.
- Go to the
Compute Engine
service. - On the right-hand side of a VM entry select
