Just a little side note: I don't think you need to maintain the hostgroup<-> host relationship in both the hostgroup and host definitions. Keep the definition in one of the two to get a cleaner code. Someone please correct me if I'm wrong. :) <div>On 12/22/08, Rahul Nabar <<a href="mailto:rpnabar@gmail.com">rpnabar@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid">I just installed Nagios and I can monitor my localhost all right. I tried to start with one of my remote compute-nodes but this does not seem to work so well. I see my new group "compute-nodes" on the web interface but it does not list the remote machine I tried adding. I'm stumped as to what I am doing wrong! To my "nagios.cfg" I added this line :cfg_file=/usr/local/nagios/etc/hosts.cfg And made a new "/usr/local/nagios/etc/hosts.cfg" like so: define hostgroup{ hostgroup_name compute-nodes alias compute-nodes members star01 } define host{ host_name star01 alias star01 address 11.0.0.1 hostgroups &n bsp; compute-nodes check_command check-host-alive max_check_attempts 5 check_period 24x7 process_perf_data 0 retain_nonstatus_information 0 contact_groups admins notification_interval 30 notification_period 24x7 notification_options d,u,r } Shouldn't this be a basic template to get me started up? What else do I need to do? Any debug suggestions? A ping to 11.0.0.1 is successful. -- Rahul ------------------------------------------------------------------------------ _______________________________________________ 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>
