Support conditional blocks inside objects

[jcharaoui]

One of the great features of Icinga2 is the ability to include code blocks within host and service definitions.

For example:

apply Service "eventlog_" for (eventlog => config in host.vars.eventlog) {
  import "generic-service"
  check_command = "eventlog-windows"
  max_check_attempts = 1 
  volatile = true
  command_endpoint = host.name
  vars += config
  assign where true
  ignore where host.vars.noagent

  if (config.check_interval) {
    check_interval = config.check_interval
  } else {
    check_interval = 1h
  }
}

Currently, it's not possible to define the if / else blocks using the Puppet module, the only alternative is to drop an extra config file.

This could be solved in the same manner as the Puppetlabs Apache module, using a custom_fragment parameter.

We discussed it years ago and decided against it. In contrast to Apache, the order is decisive and "only" at the end makes very few users happy. But you can use a fragment for an entire object, see icinga2::config::fragment.

Fair enough, thanks for taking the time to reply.
