An Ansible role that installs and configures the Librato Agent and plugins
None
None
The bare minimum required to get started is to set the email
and token
variables and include the role:
- hosts: all
roles:
- { role: librato.librato, librato_email: 'you@domain.com', 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']
cpu
df
memory
load
disk
swap
interface
apache
nginx
nginx_plus
jvm
memcached
varnish
zookeeper
docker
elasticsearch
mongodb
postgresql
mysql
redis
haproxy
To use your own custom or upstream collectd plugin, simply have another module drop the config into /opt/collectd/etc/collectd.conf.d/
and any custom plugins into /opt/collectd/share/collectd/

This role requires Ansible 2.2 or later.
Integration tests utilize kitchen-ansible
and serverspec
. To run the test suite:
- Run
bundle install
- Run
kitchen test
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 thedefault
security group. - Set
transport.ssh_key
to the path of your SSH key. It looks forid_rsa
by default.
