Question

我正在尝试在RDS实例上附加警报。但是无法使用以下AWS CLI命令获取RDS的警报名称。

aws cloudwatch describe-alarms-for-metric --namespace AWS/RDS --metric-name CPUUtilization --Dimensions Name=DBInstanceIdentifier,Value=My-DB

获取输出：

| DescribeAlarmsForMetric | + ----------------------- +

与aws cli命令一样，我试图获取在EC2实例上配置的警报及其对我有用的

aws cloudwatch describe-alarms-for-metric --region $region --metric-name StatusCheckFailed --namespace AWS/EC2 --dimensions Name=InstanceId,Value=$i --output text --query 'MetricAlarms[].[AlarmName]'

Answer 1

为了重现这种情况，我做了以下事情：

为MySQL数据库实例启动Amazon RDS
在数据库CPU使用率方面创建了Amazon CloudWatch警报

然后我运行命令：

aws cloudwatch describe-alarms-for-metric --namespace AWS/RDS --metric-name CPUUtilization --dimensions Name=DBInstanceIdentifier,Value=stack

答复为：

{
    "MetricAlarms": [
        {
            "EvaluationPeriods": 1, 
            "TreatMissingData": "missing", 
            "AlarmArn": "...", 
            "StateUpdatedTimestamp": "2019-02-13T01:21:52.988Z", 
            "AlarmConfigurationUpdatedTimestamp": "2019-02-13T01:21:52.421Z", 
            "ComparisonOperator": "GreaterThanOrEqualToThreshold", 
            "AlarmActions": [], 
            "Namespace": "AWS/RDS", 
            "AlarmDescription": "stack", 
            "StateReasonData": "...", 
            "Period": 300, 
            "StateValue": "ALARM", 
            "Threshold": 0.0, 
            "AlarmName": "stack-alarm", 
            "Dimensions": [
                {
                    "Name": "DBInstanceIdentifier", 
                    "Value": "stack"
                }
            ], 
            "Statistic": "Average", 
            "StateReason": "Threshold Crossed: 1 datapoint [2.1557377049180277 (13/02/19 01:16:00)] was greater than or equal to the threshold (0.0).", 
            "InsufficientDataActions": [], 
            "OKActions": [], 
            "ActionsEnabled": true, 
            "MetricName": "CPUUtilization"
        }
    ]
}

所以，这似乎对我来说很好。
