Logging

Ansible Logging

• By default, Ansible doesn’t log anything, information is written to STDOUT

  • log_path=: set defaults section of ansible.cfg to force writing log files

  • or set $ANSIBLE_LOG_PATH environmental variable

• Make sure to configure logrotate on ansible log files

Configure Callback Settings

• While only one callback can handle stdout at a time, you can enable additional callbacks to perform other actions. For example, the following configuration enables the ansible.posix.profile_tasks and ansible.posix.timer callbacks. The profile_tasks callback summarizes task execution time at the end of the play, and the timer callback provides timestamps for each task. Finally, the community.general.yaml stdout callback provides task output in YAML format

[defaults]
stdout_callback=community.general.yaml
callbacks_enabled=ansible.posix.profile_tasks, ansible.posix.timer 

Logging to separate file for each host

• using log_plays community callback plugin

[defaults]
inventory=./csvinv.yaml
ansible_host_checking=False
# Still log in to one common file
log_path=./ansible_log.txt
# Need to install plugin using: ansible-galaxy collection community.general
callbacks_enabled=ansible.posix.profile_tasks,community.general.log_plays
[callback_log_plays]
# logs folder will be created 
log_folder=logs
