Question

当我创建新的EC2实例时，我使用ansible dynamic inventory来创建新的cloudwatch指标警报。到目前为止一切顺利：

- name: set AWS CloudWatch alarms
  hosts: tag_env_production
  vars:
    alarm_slack: 'arn:aws:sns:123:metrics-alarms-slack'
  tasks:
    - name: "CPU > 70%"
      ec2_metric_alarm:
        state: present
        name: "{{ ec2_tag_Name }}-CPU"
        region: "{{ ec2_region }}"
        dimensions:
          InstanceId: '{{ ec2_id }}'
        namespace: "AWS/EC2"
        metric: CPUUtilization
        statistic: Average
        comparison: ">="
        threshold: 70.0
        unit: Percent
        period: 300
        evaluation_periods: 1
        description: Triggered when CPU utilization is more than 70% for 5 minutes
        alarm_actions: ['{{ alarm_slack }}']
      when: ec2_tag_group == 'lazyservers'

执行如下：

ansible-playbook -v ec2_alarms.yml -i inventories/ec2/ec2.py

创建新实例后，我删除旧实例（手动）。问题是我需要删除附加到旧实例的现有指标的警报。

我是否遗漏了某些内容，或者无法通过动态广告资源进行操作？

我目前的想法是删除＆＃34;终止＆＃34;中的实例的指标。状态，但缺点是如果我在这些实例终止后运行剧本，它们就不会被看见。

在删除实例之前，请使用以下内容删除警报：

- name: delete alarm
  ec2_metric_alarm:
    state: absent
    region: ap-southeast-2
    name: "cpu-low"
    metric: "CPUUtilization"
    namespace: "AWS/EC2"
    statistic: Average
    comparison: "<="
    threshold: 5.0
    period: 300
    evaluation_periods: 3
    unit: "Percent"
    description: "This will alarm when a bamboo slave's cpu usage average is lower than 5% for 15 minutes "
    dimensions: {'InstanceId':'{{ instance_id }}'}
    alarm_actions: ["action1","action2"]

如何删除附加到不存在的实例的云观察报警？
