History log maintains history data related to user login, user access, and changes to attributes, and elements.
If you
have enabled history logging for an attribute, you can view the attribute's
history log by clicking the
icon. History log can be used to track the changes made to
an attribute, to configure notifications based on specific changes,
or to decide whether an attribute's value should be rolled back to
a previous value using the rollback icon.
The following table lists the messages logged for an attribute, for each change type event:
