## Synopsis

- Create or delete a Rackspace Cloud Monitoring alarm that associates an existing rax_mon_entity, rax_mon_check, and rax_mon_notification_plan with criteria that specify what conditions will trigger which levels of notifications. Rackspace monitoring module flow | rax_mon_entity -> rax_mon_check -> rax_mon_notification -> rax_mon_notification_plan -> rax_mon_alarm

The below requirements are needed on the host that executes this module.

- python >= 2.6
- pyrax

auth_endpoint - | Default: "https://identity.api.rackspacecloud.com/v2.0/" | The URI of the authentication service.
check_id - / required |  | ID of the check that should be alerted on. May be acquired by registering the value of a rax_mon_check task.
credentials - |  | File to find the Rackspace credentials in. Ignored if api_key and username are provided. aliases: creds_file
criteria - |  | Alarm DSL that describes alerting conditions and their output states. Must be between 1 and 16384 characters long. See http://docs.rackspace.com/cm/api/v1.0/cm-devguide/content/alerts-language.html for a reference on the alerting language.
disabled boolean | Choices: no yes | If yes, create this alarm, but leave it in an inactive state. Defaults to no.
entity_id - / required |  | ID of the entity this alarm is attached to. May be acquired by registering the value of a rax_mon_entity task.
env - |  | Environment as configured in ~/.pyrax.cfg, see https://github.com/rackspace/pyrax/blob/master/docs/getting_started.md#pyrax-configuration.
identity_type - | Default: "rackspace" | Authentication mechanism to use, such as rackspace or keystone.
label - / required |  | Friendly name for this alarm, used to achieve idempotence. Must be a String between 1 and 255 characters long.
metadata - |  | Arbitrary key/value pairs to accompany the alarm. Must be a hash of String keys and values between 1 and 255 characters long.
notification_plan_id - / required |  | ID of the notification plan to trigger if this alarm fires. May be acquired by registering the value of a rax_mon_notification_plan task.
region - | Default: "DFW" | Region to create an instance in.
state - | Choices: present ← absent | Ensure that the alarm with this `label` exists or does not exist.
tenant_id - |  | The tenant ID used for authentication.
tenant_name - |  | The tenant name used for authentication.
username - |  | Rackspace username, overrides credentials.
validate_certs boolean | Choices: no yes | Whether or not to require SSL validation of API endpoints. aliases: verify_ssl

## Notes

Note

- The following environment variables can be used, `RAX_USERNAME`, `RAX_API_KEY`, `RAX_CREDS_FILE`, `RAX_CREDENTIALS`, `RAX_REGION`.
- `RAX_CREDENTIALS` and `RAX_CREDS_FILE` points to a credentials file appropriate for pyrax. See https://github.com/rackspace/pyrax/blob/master/docs/getting_started.md#authenticating
- `RAX_USERNAME` and `RAX_API_KEY` obviate the use of a credentials file
- `RAX_REGION` defines a Rackspace Public Cloud region (DFW, ORD, LON, ...)

## Examples

    - name: Alarm example
      gather_facts: False
      hosts: local
      connection: local
      tasks:
      - name: Ensure that a specific alarm exists.
        rax_mon_alarm:
          credentials: ~/.rax_pub
          state: present
          label: uhoh
          entity_id: "{{ the_entity['entity']['id'] }}"
          check_id: "{{ the_check['check']['id'] }}"
          notification_plan_id: "{{ defcon1['notification_plan']['id'] }}"
          criteria: >
            if (rate(metric['average']) > 10) {
              return new AlarmStatus(WARNING);
            }
            return new AlarmStatus(OK);
        register: the_alarm
