I notice that some modules use ‘module.debug’ for logging, but I can’t find any docs on it. I skimmed the function definition in AnsibleModule and it appears that when the module has the \_debug attribute set, it tries to log to syslog. I’m trying to get this to work in ansible-test, but I can’t make it happen, even when I pass --debug in. How does this feature work? ---

short answer: ANSIBLE\_DEBUG=1 activates it long answer: This is integrated into AnsibleModule (lib/ansible/module\_utils/basic.py), which has a 'debug' method, this method will write to the local syslog/systemd. The method is activated when the module receives an `_ansible_debug` parameter that is True, which ansible itself sends if 'debug is enabled' via the configuration (env var above or in ansible.cfg). It will turn off if you use no\_log or have the no\_target\_syslog setting to avoid disclosure. I hope that helps ---

That’s very helpful, thanks!
