ansible.builtin.tree – Save host events to files


This callback plugin is part of ansible-core and included in all Ansible installations. In most cases, you can use the short plugin name tree even without specifying the collections: keyword. However, we recommend you use the FQCN for easy linking to the plugin documentation and to avoid conflicting with other collections that may have the same callback plugin name.

New in version 2.0: of ansible.builtin


  • This callback is used by the Ansible (adhoc) command line option -t|–tree

  • This produces a JSON dump of events in a directory, a file for each host, the directory used MUST be passed as a command line option.


The below requirements are needed on the local controller node that executes this callback.
