The service definition on the distributed remote host must link to a local service via check_command to do its stuff, I assume, like check_disk. </FONT></DIV> <DIV><FONT face=Arial size=2>Thats all fine, and I think this is working okay. </FONT></DIV> <DIV><FONT face=Arial size=2>The Nagios central server host must also have the service definition but *can't* have a check_command because its not a local service (in the case of check_disk). So presumably you need to enable passive checks for this particular service and check freshness and then link to a host_name which is your remote host (although defined on the Nagios central server as well as locally on the remote host Nagios install). </FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>Still confused.
