Okay, let's see it as a feature J even though it was kinda confusing me that it 
was possible via this way (without using "+") to have one host in two different 
hostgroups.

Hi Jean,

 

Let me try to explain again it in "old fashioned" Nagios style. I setup a host 
in hosts.cfg where I tell the host to use a template configuration from 
templates.cfg. Within the template there is a hostgroup defined, so all hosts 
that are assigned to that template should be in that hostgroup.

Additionally I used the hostgroups.cfg file and created a different hostgroup, 
where I added the host already defined with the template.

This causes to have two different groups with the same hosts and I am not sure 
if that is really wanted.

 

Simple example:  

 

templates.cfg

 

define host{

                name                                                      
linux-server        

                use                                                          
generic-host       

                check_period                                      24x7          
             

                check_interval                                   5              
                

                retry_interval                                     5            
                  

                max_check_attempts                     2                        
      

                check_command                              check_dummy!0        
       

                notification_period                          24x7

                notification_interval                        1                  
            

                notification_options                        d,u,r               
        

                contact_groups                                 admins           
       

                register                                                 0      
                        

                hostgroups                                          
ServeursRedHat

                }

 

 

hosts.cfg :

 

define host{

                use                                                          
linux-server

                contact_groups                                 admins

                host_name                                          srv-ipvs-1

                realm                                                      EMEA

                alias                                                         
srv-ipvs-1

                address                                                 
192.168.0.1

                check_interval                                   1

                check_command                               check_host_alive

        }

 

hostgroups.cfg:

 

define hostgroup{

                hostgroup_name                              sql_server          
 

                alias                                                         
SQL Servers         

                members                                              srv-ipvs-1 
    

                realm                                                      EMEA

        }

 

This will end up Thruk displaying two hostgroups (ServeursRedHat and 
sql_server) with the srv-ipvs-1 hosts assigned to each hostgroup.


Hi,

Thans for this example. I think it's a feature. I think it's a valid way of 
doing, There are two ways of adding host into hostgroups, and I think it's a 
pure additive way. If I'm not wrong, Nagios is also doing as this too.

So "not a bug, it's a feature" seems true here :)


Jean

         

        So I thought if one group should be overwritten, so just one is 
displayed, or if that is a wanted feature.

        Hi all,

        Hi,
         

                 

                when I use a template where a hostgroup is already defined and 
then also assign a hostgroup_name which is different from the one in the 
template in the hostgroup.cfg, I can see two entries through the Thruk 
interface, with the same host being in the two different hostgroups. Not sure 
if that is really a feature, but from my point of view it seems to be a bug, 
because generally, the "last" configuration options of the host, service, etc.  
usually overwrites the top level or template confs.

        Yes, the template should over right the host one, unless this value 
start with a '+' (additive inheritance). But here it's another problem if I can 
understand : you set a hostgroup in the host configuration, and in another 
hostgroup, you set this host as a member is that right?
        
        If I'm not wrong such configuration say "add to both" in Nagios, and it 
sound logical to me (you got 2 way of adding into hostgroups, I don't think one 
is a preferred way to the other).
        
        Is it a configuration inherited from a Nagios ?
        
        Thanks,
        
        
        Jean
