Nagios Support Forum

We have modified several host templates so they have site specific defaults. What we want to be able to do is to use the Host Creation Tool, select Network device and have it use
the Network template we have created. This would allow us to import mutliple network devices and have them all receive the default settings and contacts that all network devices will
use. So how could we change the template from the genericnetwork device to our own template.

thanks,

You have 3 options:
1) Change the generic template.
2) Add a new template after the wizard process.
3) Alter the php source for the wizard to use a different template.

Thanks for the suggestions. Modifying existing templates seems like the easiest option. If I modify existing templates, will upgrades to Nagios wipe out these modified templates?

Yes.

You could create an alternatively named version of the Wizard which will prevent this from happening.

Here's a talk I did on customizing wizards:

And Jake Omann has also done a talk on it:

So we have taken a copy of the Hostcreation tool and are modifying it to use our custom host templates. We have a generic_host template that contains all basic settings that will apply to
all devices. (This is our base level). Then we have a 'router_switch_host' template that has setting specific to the router or switch, like an addtional contact group and a hostgroup. The template
references back to the generic_host template.
I would like to verify the following:
1) For the devices we are adding: we select the Switch from the HostCreation Tool. We have modified it so it uses the router_switch_host template.
These devices will pick up the settings from the generic_host template and add any additional setting from the router_switch_host template. - True?
2) Any settings from the host creation tool will not be used if they are defined in one of these two templates. - True?
I noticed that these settings that are defined in the templates including the hostgroup the devices get assigned to only display when looking at the devices in core. It would
be nice when looking at the host in config mgr you could see what settings have been applied to that host or at least provide a link back to each template that has been applied.
This way you can see it in a single view from the host you are looking at while in config mgr.

Yes this is true. If the generic template and the switch template have conflicting options, then the switch template will "win". Then on the actual host definition, if those settings are also defined then these will "win". It's a layering effect.

When a setting is selected in a wizard, that setting will be used as it will be defined in the host object itself and any settings in the host object "win" over templates.

This sounds like a good feature request.

Got it!! Thanks.
