Hello Anil,
currently we do not have change docs for the CUA landscape, but soon they will be available.
Please search form time to time for notes with the words 'RSUSRCUA' / 'SCUH'.
So Laxmans suggestion may help you.
Regarding Monitoring option in scua: this funciotn is described in SAP note 1645544. As only scul-entries are monitored then by ccms, this won't help regarding configuration changes.
