Boto/Cloudwatch恢復實例鬧鐘

我一直在撞牆試圖做這項工作。我正在嘗試使用python/boto創建恢復失敗的ec2實例的cloutwatch警報。我在獲取ec2：RecoverInstance操作時很困難。我懷疑我的話題沒有正確設置。Boto/Cloudwatch恢復實例鬧鐘

topics = sns_conn.get_all_topics() 

topic = topics[u'ListTopicsResponse']['ListTopicsResult']['Topics'][0]['TopicArn'] 

# arn:aws:sns:us-east-1:*********:CloudWatch 

status_check_failed_alarm = boto.ec2.cloudwatch.alarm.MetricAlarm(
     connection=cw_conn, 
     name=_INSTANCE_NAME + "RECOVERY-High-Status-Check-Failed-Any", 
     metric='StatusCheckFailed', 
     namespace='AWS/EC2', 
     statistic='Average', 
     comparison='>=', 
     description='status check for %s %s' % (_INSTANCE, _INSTANCE_NAME), 
     threshold=1.0, 
     period=60, 
     evaluation_periods=5, 
     dimensions={'InstanceId': _INSTANCE}, 
     # alarm_actions = [topic], 
     ok_actions=[topic], 
     insufficient_data_actions=[topic]) 

# status_check_failed_alarm.add_alarm_action('arn:aws:sns:us-east-1:<acct#>:ec2:recover') 
# status_check_failed_alarm.add_alarm_action('arn:aws:sns:us-east-1:<acct#>:ec2:RecoverInstances') 
status_check_failed_alarm.add_alarm_action('ec2:RecoverInstances') 

cw_conn.put_metric_alarm(status_check_failed_alarm)

任何建議將不勝感激。

謝謝。

在哪裏定義了「topic」。您可以查詢所有主題，例如'sns = connect_to_region（...）; topics = sns.get_all_topics（）'或者只需在AWS管理控制檯中查找SNS ARN。它應該看起來像'arn：aws：sns：：：'。 – AChampion

嗨AChampion - 我已更新我的代碼以顯示主題 - 檢索部分。 –

我認爲這個問題是這些警報操作沒有<acct>在arn。該cli reference記錄了有效arn S：

有效值：阿爾恩：AWS：自動化：區域：EC2：停止| arn：aws：automate：region：ec2：terminate |阿爾恩：AWS：自動化：區域：EC2：恢復

我會覺得更容易從AWS拉指標，並創建從報警而不是試圖達到從地面構造它，例如（未經測試的代碼）：

topics = sns_conn.get_all_topics() 
topic = topics[u'ListTopicsResponse']['ListTopicsResult']['Topics'][0]['TopicArn'] 

metric = cloudwatch_conn.list_metrics(dimensions={'InstanceId': _INSTANCE}, 
             metric_name="StatusCheckFailed")[0] 
alarm = metric.create_alarm(name=_INSTANCE_NAME + "RECOVERY-High-Status-Check-Failed-Any", 
          description='status check for {} {}'.format(_INSTANCE, _INSTANCE_NAME), 
          alarm_actions=[topic, 'arn:aws:automate:us-east-1:ec2:recover'], 
          ok_actions=[topic], 
          insufficient_data_actions=[topic], 
          statistic='Average', 
          comparison='>=', 
          threshold=1.0, 
          period=60, 
          evaluation_periods=5)
