short_description: adds time information to tasks
version_added: "2.0"
description:
- Ansible callback plugin for timing individual tasks and overall execution time.
- "Mashup of 2 excellent original works: https://github.com/jlafon/ansible-profile,
https://github.com/junaid18183/ansible_home/blob/master/ansible_plugins/callback_plugins/timestamp.py.old"
- "Format: ``<task start timestamp> (<length of previous task>) <current elapsed playbook execution time>``"
- It also lists the top/bottom time consuming tasks in the summary (configurable)
- Before 2.4 only the environment variables were available for configuration.
requirements:
- whitelisting in configuration
options:
