Quickstart

The bare minimum required to get started is to set the email and token variables and include the role:

- hosts: all
  roles:
    - { role: AerisCloud.librato, librato_email: '[email protected]', librato_token: 'your-token-here' }

By default, the following plugins are enabled: cpu, df, disk, swap, memory, load.

To include a plugin, set any variables you need for it, then add it to the librato_enabled_plugins variable:

- hosts: all
  vars:
    librato_apache_path: '/my-status-endpoint'
    librato_enabled_plugins: ['apache']

Supported Ansible Versions

Development

Testing

Integration tests utilize kitchen-ansible and serverspec. To run the test suite:

Run bundle install
Run kitchen test. To run an individual test, run kitchen test [platform name]. E.g. kitchen test centos-7.

Testing Amazon Linux

Testing Amazon Linux through test-kitchen requires a bit more setup:

Ensure kitchen-ec2 is installed: gem install kitchen-ec2
Update .kitchen.yml to have the correct AWS key ID you're going to use
Set security_group_ids in the driver section to include a security group accessible from your laptop. Not setting this will use the default security group.
Set transport.ssh_key to the path of your SSH key. It looks for id_rsa by default.
