These are few things which I have shared for loving helpdesk engineers who help us to achieve healthy sccm environment.
ccmsetup - for checking ccmsetup installation and uninstallation activity logs
ccm - for checking downloaded content cache, client's logs, inventory, metering and other client related information
ccm/smsrap.cpl - for checking available programs listed on client's Run Advertised Programs under Control panel
Cheers!
