How can i create a report on the basis of change of event on portlet UI

Suppose i have added a new attribute in identity vault ( say Boolean ),
i have to create a report, when this Boolean values changes for
particular user profile. The value change will happen on portlet UI. I
need to show which user is changed and by whom with time stamp on
report. I have seen all imported reports in repository, but not able to
relate my requirement with those reports. I know i have to add custom
attribute with Data collection driver but how the report will generate
