ARA records Ansible playbook runs seamlessly to make them easier to visualize, understand and troubleshoot.
ARA doesn't run your playbooks for you: it integrates with Ansible as a callback plugin wherever it is.
Whether you are running Ansible from your personal laptop or a server,
all you need to do is to install ARA,
configure Ansible to use ARA and you're good to go.
The ARA project puts a lot of emphasis on being simple to install and use without requiring you change your existing Ansible workflows.
You can read about the project's core values and principles in the project manifesto.
The ARA database is empty or the web application is not configured properly to find your playbook data.
