Alarm action definition in ec2_metric_alarm ansible module

Question

I am trying to set up an cloud watch alarm witch ansible ec2_metric_alarm module and I do not know how to set it to send an email on alarm

The code is

- name: add alarm
  ec2_metric_alarm:
    state: present
    region: eu-west-1
    name: "LoadAverage"
    metric: "LoadAverage"
    statistic: Average
    comparison: ">"
    threshold: 3.0
    evaluation_periods: 3
    period: 60
    unit: "None"
    description: "Load Average"
    dimensions: {'Role':{{itme[0]}}, Node:{{item[1]}} }
    alarm_actions: ["action1","action2"]

What is the syntax or what do I do to express that I want it to send emails on in alarm_actions?

Answer 1

The documentation is crappy for this one:
http://docs.ansible.com/ec2_metric_alarm_module.html

Here is what I would try based on boto:
http://docs.pythonboto.org/en/latest/ref/cloudwatch.html#module-boto.ec2.cloudwatch.alarm

alarm_actions (list of strs) – A list of the ARNs of the actions to take in ALARM state

The current supported ARNS are SNS topics or autoscalling policies.

In your case:
You need to create an SNS topic and subscribe your email address to that topic (also confirm the subscription) and after that put the SNS topic ARN as a string in the alarm_actions param that you pass to the ansible ec2_metric_alarm_module.

Hope this helps.
