One common use case for Change Detection is identifying significant variances in key metrics at the system level. Metrics of interest here may include CPU usage, zIIP usage, percent utilization of the CPC, and overflow of zIIP-eligible work to general purpose CPs. In this example, there was a significant increase in CPU on the selected day compared against the previous 30 days.
