time - 运行ansible-playbook时如何测量和显示任务所花费的时间？

Question

我有一本剧本，在这本剧本中，有很多任务。我需要知道哪个任务花费了多少时间？

有什么解决办法吗？

Answer 1

添加 callback_whitelist = profile_tasks在 [default] ansible.cfg 中的部分

这是我的 ansible.cfg

[defaults]
inventory = hosts
callback_whitelist = profile_tasks
deprecation_warnings = False

这是我的剧本

- hosts: localhost
  gather_facts: true
  tasks:
    - name: Sleep for 10 Sec
      command: sleep 10

    - name: Sleep for 5 Sec
      command: sleep 5

    - name: Sleep for 2 Sec
      command: sleep 2

这是我的播放输出。
