I am sorry for opening an old issue, but I have a question in regard to this style of config, and this is the closest thread I have found to my issue. I am using Nagios 2.0b6, and want to completely do away with the hostgroup definitions in favor of defining it in the host definition, but am having problems. I am using the object inheritance templates like you, but when I run nagios -v I get Error: Could not find hostgroup 'Core_Monitors' specified in host 'cacti' definition (config file '/opt/nagios/etc/core/core_hosts.cfg', starting on line 83) Am I allow to do this? According to the documentation I can use just the hostgroups line in the host definition as an alternative to a hostgroups definition. As a fix I tried making a hostgroup definition, but without the members line, since all my members will be defined in the host definition, this just changed the error to Error: Hostgroup has no members (config file '/opt/nagios/etc/corenap/corenap_hostgroups.cfg', starting on line 1) which I expected. So, to sum up my question. Is nagios at a point where I don't have to define a hostgroup and can just use the hostgroup line in the hosts definition. Thanks for your response. -Zac Israel <div>On 8/12/05, Todd Barbera <<a href="mailto:todd_barbera@wgbh.org">todd_barbera@wgbh.org</a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Thanks Marc, This did the trick. I was able to clean up my config files considerably using the templates.

Thanks for the feedback. No you can't. A suitable alternative for you might be using the "hostgroups" directive in each of your host definitions. <a href="http://nagios.sourceforge.net/docs/2_0/xodtemplate.html#host"> http://nagios.sourceforge.net/docs/2_0/xodtemplate.html#host</a> You could even simplify that further by using a per-file template. Presuming you already have a generic global host template defined you could do the following in etc/servers/sunservers.cfg - define host { use generic-host name sunservers hostgroups sunservers register 0 } define host{ use sunservers host_name Sun_Host_1 alias This is my Sun Host. address <a href="http://127.0.0.1">127.0.0.1</a> } define host{ use sunservers host_name Sun_Host_2 alias This is my Second Sun Host. address <a href="http://127.0.0.2">127.0.0.2</a> } I haven't actually done this myself but I expect the template inheritance to allow it. -- Marc ------------------------------------------------------- SF.Net email is Sponsored by the Better Software Conference & EXPO September 19-22, 2005 * San Francisco, CA * Development Lifecycle Practices Agile & Plan-Driven Development * Managing Projects & Teams * Testing & QA Security * Process Improvement & Measurement * <a href="http://www.sqe.com/bsce5sf">http://www.sqe.com/bsce5sf</a> _______________________________________________ Nagios-users mailing list <a href="mailto:Nagios-users@lists.sourceforge.net"> Nagios-users@lists.sourceforge.net</a> <a href="https://lists.sourceforge.net/lists/listinfo/nagios-users">https://lists.sourceforge.net/lists/listinfo/nagios-users</a> ::: Please include Nagios version, plugin version (-v) and OS when reporting any issue. ::: Messages without supporting info will risk being sent to /dev/null ------------------------------------------------------- SF.Net email is Sponsored by the Better Software Conference & EXPO September 19-22, 2005 * San Francisco, CA * Development Lifecycle Practices Agile & Plan-Driven Development * Managing Projects & Teams * Testing & QA Security * Process Improvement & Measurement * <a href="http://www.sqe.com/bsce5sf">http://www.sqe.com/bsce5sf</a> _______________________________________________ Nagios-users mailing list <a href="mailto:Nagios-users@lists.sourceforge.net">Nagios-users@lists.sourceforge.net </a> <a href="https://lists.sourceforge.net/lists/listinfo/nagios-users">https://lists.sourceforge.net/lists/listinfo/nagios-users</a> ::: Please include Nagios version, plugin version (-v) and OS when reporting any issue. ::: Messages without supporting info will risk being sent to /dev/null </blockquote></div>
