If there is a problem with the reports, warnings appear in the Live and Timeline views. Clicking the tag displays a list of error messages, alerting you to the type and severity of problems.
The tag indicates the number of warnings that occurred. If there are no issues, the tag is not displayed.
The warnings are sorted by type and each is given a color-coded warning icon that tells you the severity of the issue:
The issue is critical. For example, a connection timeout caused the termination of the capture, leaving you with incomplete data.
The issue is medium severity. For example, power data from the Energy Probe could not be correlated with other data on the timeline.
The issue is minor. For example, a chart exists in the report but there is no counter data from the capture session to populate it.
