Custom Ansible Callback not receiving group_vars/host_vars

Question

I have a custom ansible callback that I am writing:

class CallbackModule(CallbackBase):
  CALLBACK_VERSION = 2.0
  CALLBACK_TYPE = \'aggregate\'
  CALLBACK_N         


        

Answer 1

Excellent @techraf helped me figure this out. I needed to capture the Play's Variable Manager:

class CallbackModule(CallbackBase):
    CALLBACK_VERSION = 2.0
    CALLBACK_TYPE = 'aggregate'
    CALLBACK_NAME = 'is'

    def v2_playbook_on_play_start(self, play):
      self.vm = play.get_variable_manager()

    def v2_runner_on_ok(self, result):
      host_vars = self.vm.get_vars()['hostvars'][result._host.name]
      var_that_i_want = host_vars['var_that_i_want']
