[Nagios-devel] undesirable verification outcome

[kray1 <kr...@tr...>]

Hi again,
"hostgroup_name" works great with b2 but found a undesirable.
if the hostgroup you specify in a service doesnt exist you get the following
error on verify,
"Error: Could not find hostgroup ', ' specified in service

***> One or more problems was encountered while processing the config
files...
     Check your configuration file(s) to ensure that they contain valid
     directives and data defintions.  If you are upgrading from a previous
     version of Nagios, you should be aware that some variables/definitions
     may have been removed or modified in this version.  Make sure to read
     the HTML documentation on the main and host config files, as well as the

     'Whats New' section to find out what has changed.
"

here is an example of the service that produced the above error.
# Service definition
define service{
        use                             generic-service
        hostgroup_name                  test,production,qa,dumbuser
        service_description              reboot
        is_volatile                     0
        check_period                    24x7
        max_check_attempts              5
        normal_check_interval           5
        retry_check_interval            1
        contact_groups                  Unix-page-alert
        notification_interval           10
        notification_period             workhours
        notification_options            w,u,c,r
        check_command                   check_reboot
        }
where dumbuser doesn't exist as a host group. again this is protecting the
user against himself really, and you cant trap all the errors(and the message
is close enough to allow you to find your problem).  but i thought you might
want to know. if the hostgroups does exist, the comma is valid. so if i were
to say "test,production,qa" in the above everything would be fine.(meaning:
yay!!!)


Also a difference i noticed between "Netsaint" and "Nagios" is that Netsaint
allowed multi-grouped hosts. where nagios doesn't this makes total sense if
you are using "hostgroup_name" for a service
and it appears that this is the only time it will spit out an error.
IE: Myserver exist in production and qa using the above example, you get a
"service already defined, for Myserver. wonder why this could be *smile*
this is not an issue with my configuration because i dont want multi-grouped
hosts. but other people might?
*realizes how would the programer determine which hostgroup takes precendence
over the other*
