The "Attrition Drilldown (to track)" is at alpha level of quality on ASM machines right now. Due to a known issue that will take significant effort to fix, it does not yet work reliably on all ASM machines. You will notice gaps in the data where no track is listed when this happens. The problem is worse on some sites than others.
ASM users should use the "Attrition Drilldown (to segment)" real-time dashboard for now for production purposes and treat "Attrition Drilldown (to track)" as an early release for feedback.
Additionally, be aware that ASM machines with software < 700 do not generate the required information for component level mispick assignment, so the dashboard will not work on these machines at all.
