<pre>Hi, Thanks for all your replies. What I would like to accieve is to: create service dependencies for multiple services that are dependent on services on the same host - BUT for multiple hosts (all hosts running this service) So Andy - this would only solve a bit of the "problem"... If you have a very dynamic infrastructure i believe you still need to add/remove servicedependencies each time you add/remove a host ? If it was possible to use a variable like: dependent_host_name $HOSTNAME$ this could make fx NRPE executed services dependent on NRPE for all hosts running NRPE. This would really be a neet feature ! Thanks in advance ! ~maymann --- Hi, I'm sure this has been implemented in Nagios 3. I wrote an on-line application that generated service dependencies for individual hosts/services in a group in Nagios 2, and I'm sure I read that was now no longer an issue in v3. From the manual - <a rel="nofollow" href="http://nagios.sourceforge.net/docs/3_0/objecttricks.html#same_host_dependency:" target="_top">http://nagios.sourceforge.net/docs/3_0/objecttricks.html#same_host_dependency:</a> "If you want to create service dependencies for multiple services that are dependent on services on the same host, leave the /dependent_host_name/ and /dependent_hostgroup_name/ directives empty." Is this what you were trying to achieve?
