Slasing, you're right, i could do that, but wouldn't because that would defeat the purpose of using the wizard.

I am aware that both host/service objects needs to exist for every definition... however, by default, the wizard usually configures it as one or the other, no?

What, I'm trying to find out is how to easily determine what type of check it was configured as (by default).

Thanks much,

klee

If you view the host config in the CCM and it has a check_ping command assigned to it, then the ping check is on the host. If however you have a separate service with check_ping and that service is attached to the host, then the ping check is on the service. Have you used the CCM at all?

All "checks" are perfomed by commands. To see this for a host:

• Open Core Configuration Manager
  Under Monitoring click Hosts
  Click on localhost
  Here you will see Check command ... this is where the check command is defined .... but in this case it's BLANK!
  It's BLANK because the check command is defined in a template
  Soooo to see the template click the Manage Templates button
  We can see here the Assigned template is linux-server
  Click Close
  Click Abort
  On the left pane click Templates
  Click Host Templates
  Click linux-server
  Here you can see it is using the check command check-host-alive
  Which you can see underneath uses the plugin check_icmp

So that is how the host up or down state is determined.

Yes, you can also create a ping service. You'll notice when using the Windows Wizard one of the first services is ping. This is often created when you want to define service dependancies.

As explained before, there is always a host object and it will have service objects. So the host object is a ping test within itself, but you can also create a ping service for that host. These are two different things, so it's not one or the other, it can be both.

I suggest you go to this documentation that explains macros:

If you want to see if a host or service object was created by a wizard:

• Open Core Configuration Manager
  Under Monitoring click Hosts
  Click on one of the hosts
  Click the Misc Settings tab
  Click the Manage Variable Definitions button
  Here there will be a definition like _xiwizard

NOTE: If you copy a host or service object, this information will be copied with it ... so that kinda could be misleading.

@tmcdonald:

My current ping polling setup (configured via Generic Network Device Wizard) pings seem to be set up in the service definition by default.

Service definition:
service_description ping
use xwizard_genericnetdevice_ping_service

Host definition:
check_command check-host-alive

Thanks for all of the input.

I guess the answer is "there is no easy way"

I'll look very carefully at the host and service definitions.

Please kindly close thread.

Thanks,
