Metrics Data is Missing
If metrics data for a resource is missing, see the following possible causes and solutions:
|No data: Resource creation date.||The resource was created before the metrics feature was available.||
Deactivate then reactivate the resource to start the flow of metrics data.
|No data: Permissions issue.||The user is missing a policy for metrics.||
An administrator user needs to add a policy statement to read metrics for your group, see let users view or access metric definitions in a compartment. For example:
|No data: Misaligned chart time range.||The chart range (time period or x-axis window) doesn't cover the time of notebook session use.||
Adjust the chart range or time period as necessary.
