設定警示以建立調查

在帳戶中設定調查群組之後，您可以設定現有的 CloudWatch 警示，以便在調查進入 ALARM 狀態時自動建立調查。這不需要手動開始調查，並確保對操作問題的一致回應。您可以使用管理主控台 AWS CLI CloudFormation、或 AWS SDKs來設定警示 AWS 。

Console

透過 https://console.aws.amazon.com/cloudwatch/ 開啟 CloudWatch 主控台。
在導覽窗格中，選擇警示，然後選取現有的警示。
選擇 Actions (動作)、Edit (編輯)。
在警示動作區段中，選擇新增警示動作。
在設定動作、調查動作區段下，選擇調查群組 ARN。
（選用）將重複資料刪除字串新增至群組相關警示。
選擇 Update alarm (更新警示)。

CLI

此命令要求您為 alarm-actions 參數指定 ARN。如需如何建立 ARN 的相關資訊，請參閱 ARN 格式和參數。

使用 InvestigationGroup 動作設定 CloudWatch 警示 (AWS CLI)

如果您尚未安裝和設定 AWS CLI。如需相關資訊，請參閱安裝或更新最新版本的 AWS CLI。
執行下列命令以收集您要設定之警示的相關資訊。
```
aws cloudwatch describe-alarms --alarm-names "alarm name"
```

執行下列命令以更新警示。將每個範例資源預留位置取代為您自己的資訊。


aws cloudwatch put-metric-alarm --alarm-name name \
--alarm-description "description" \
--metric-name name --namespace namespace \
--statistic statistic --period value --threshold value \
--comparison-operator value \
--dimensions "dimensions" --evaluation-periods value \
--alarm-actions "arn:aws:aiops:region:{account-id}:investigation-group/{investigationGroupIdentifier}#DEDUPE_STRING={my-dedupe-string}"

範例如下。


//Without deduplication string
aws cloudwatch put-metric-alarm --alarm-name cpu-mon \
--alarm-description "Alarm when CPU exceeds 70 percent" \
--metric-name CPUUtilization --namespace AWS/EC2 \
--statistic Average --period 300 --threshold 70 \
--comparison-operator GreaterThanThreshold \
--dimensions "Name=InstanceId,Value=i-12345678" --evaluation-periods 2 \
--alarm-actions arn:aws:aiops:us-east-1:123456789012:investigation-group/sMwwg1IogXdvL7UZ \
--unit Percent

//With deduplication string
aws cloudwatch put-metric-alarm --alarm-name cpu-mon \
--alarm-description "Alarm when CPU exceeds 70 percent" \
--metric-name CPUUtilization --namespace AWS/EC2 \
--statistic Average --period 300 --threshold 70 \
--comparison-operator GreaterThanThreshold \
--dimensions "Name=InstanceId,Value=i-12345678" --evaluation-periods 2 \
--alarm-actions arn:aws:aiops:us-east-1:123456789012:investigation-group/sMwwg1IogXdvL7UZ#DEDUPE_STRING=performance \
--unit Percent

CloudFormation

本節包含可用來設定 CloudWatch 警示以自動建立或更新調查的 CloudFormation 範本。每個範本都要求您為 AlarmActions 參數指定 ARN。如需如何建立 ARN 的相關資訊，請參閱 ARN 格式和參數。


//Without deduplication string
Resources:
  MyAlarm:
    Type: AWS::CloudWatch::Alarm
    Properties:
      AlarmActions:
        - !Sub "arn:aws:aiops:${AWS::Region}:${AWS::AccountId}:investigation-group/{investigationGroupIdentifier}"

//With deduplication string
Resources:
  MyAlarm:
    Type: AWS::CloudWatch::Alarm
    Properties:
      AlarmActions:
        - !Sub "arn:aws:aiops:${AWS::Region}:${AWS::AccountId}:investigation-group/{investigationGroupIdentifier}#DEDUPE_STRING={my-dedupe-string}"

SDK

本節包含 Java 程式碼片段，可用來設定 CloudWatch 警示以自動建立或更新調查。每個程式碼片段都要求您為 investigationGroupArn 參數指定 ARN。如需如何建立 ARN 的相關資訊，請參閱 ARN 格式和參數。
