Hi Sumant,
If there aren't any security measures preventing a user from removing RCA or formatting his or her desktop, the last connect time stated in the reports can be used to diagnose which agents haven't connected to the server. If they were supposed to connect and haven't, you can then remote to the machine and check if the missed connect is due to an uninstallation of RCA/formatting of the machine, or if something else happened that prevented the connect from running.
Regards,
Ana
