I now changed it to:
$hostgroups_parameter = generate (some command)
@@nagios_host { "$hostname":
use => "generic-host",
address => $fqdn,
alias => $hostname,
ensure => present,
target => "$nagios::common::nagios_conf_test/host-$hostname.cfg",
hostgroups => $hostgroups_parameter ? {
"" => undef,
default => "$hostgroups_parameter",
},
}
but the error remains.
Pointers still very much appreciated!!
Best regards,
Martijn.
