The screen History analysis provide means to analyze the logged data.
The purpose of logging is to be able to determine when a record was changed and what that change was. IAM maintains logs for Roles, OpenID and General data about projects and users. The logs can be found via the Advanced menu, menu group Logging and then History Analysis.
The example below shows the Applications tab on the History Analysis screen. The list of data includes all changes made to all records in Applications. If a cell is colored yellow, the value of the column that contains the cell has been changed. If the Valid to field is blue, the record has been deleted. The moment of the deletion is stored in the Valid to field.
