There are different options. You can use a basic TCP socket server in line mode with a custom protocol like Client> get database status Server> database status OK Client> get processing status Server> processing status ERROR which can be integrated into Nagios-compatible tools with the "check_tcp" plugin . The "OverbyteIcsTcpSrv.dpr" ICS demo might be helpful as a starting point here. Another option would be to integrate a HTTP server component which returns application status as a HTML page. This allows you to make quick checks with a browser and you easily can add authentication e.g. by enabling HTTP digest auth. Integration into Nagios-like tools can be done with the "check_http" plugin . The "OverbyteIcsWebServ.dpr" ICS demo might be helpful if you want to explore in that direction. BTW: I am using Icinga  for monitoring which is compatible to Nagios plugins.
