OS change event distribution gives a quick view of the types and frequency of OS changes. You can see the guest image change event distribution in multiple views. This enables you to quickly drill down to the set of events that you want to analyze. You can:
View the events in a bubble chart.
View and filter the list of events in a table under the bubble chart and optionally hide the chart.
View the events in a list grouped by OS change type and expand or contract the group to see more or less detail.
View the OS changes in a tree view, where you can drill down to multiple levels of detail within a set of related changes.
