Apply rule 'Service' does not match anywhere! - debugging

Icinga 2
1

Hello,

I get this warning on one of the satellites.

I would like to get more insight into this warning. I ran “icinga2 daemon -C -x debug” but other than warning , I don’t see any other related details.

How do I debug the apply rule on a satellite ?

Please advise

Thanks

Can you show us the service apply rule and maybe on of the host configs that it should apply to?

Here is the config info

apply Service "App2" {
    import "generic-service"
       check_command = "appcheck"
       vars.user = "test"
       if ( host.vars.tcp_ports ) { vars.portarg = true }
       check_interval = 5m
       assign where check_ifapp2host(host) 

}

object Host "test_host" {
  import "generic-linux-host"

  address = "X.X.X.X"
  vars.app = ["App2"]
  vars.location = "DC"
}

Thanks

I tried to use “debugger” on the satellite in the service config in /var/lib/icinga2/api… but it didn’t work while using 'icinga2 daemon -C -X"

So I’m not sure how to debug such problem at the satellite end.

Thanks

Does the function “check_ifapp2host” return true for the host in question?

Yes , it does.

The issue turned out that one of the satellites was running a newer version of “icinga2” version. As soon as I downgraded it, the apply rule worked on it.

Still want to understand… how to troubleshoot such issue on a satellite though…

Thanks
