Trace mask violations are reported failure. The very first email-generated report that is issued will always show 1 fail count for each channel reported on in the notification. This failure report is generated shortly after starting trace capture in Trace Acquire regardless of the frequency specified in the notification settings.
Subsequent email reports reflect the actual failed trace totals. The first report counts 1 per channel as shown in the Vision Failure Report example below in Figure: Trace Mask Failure Report.
