title: How to debug Ansible issues?
body: <p>Sometimes, <code>ansible</code> doesn't do what you want. And increasing verbosity doesn't help. For example, I'm now trying to start <code>coturn</code> server, which comes with init script on <code>systemd</code> OS (Debian Jessie). Ansible considers it running, but it's not. How do I look into what's happening under the hood? Which commands are executed, and what output/exit code?</p>
