Intro

The steps showed in this guide are the same followed in the demonstration video. Please adapt them to match your cluster configuration. The Ansible inventory file for any playbook/task showed in this exercise is:

[master]
master.hpc              ansible_connection=local

[clusters]
c01
c02
c03

Of course, if you have configured the dynamic inventory with Cobbler, no inventory file is needed. The configuration shown in this guide corresponds to the unicast Ganglia mode.
