有什么方法可以使用AmazonEC2 API查看和EC2实例的AlarmStatus值？

Question

我想知道是否有办法通过AmazonEC2 API查看ec2实例的警报状态？

我们使用AmazonCloudWatch.GetMetricStatistics方法实现了一个工作解决方案来获取特定的指标值：

var reg = new GetMetricStatisticsRequest()
            {
                MetricName = metric,
                Period = 60 * 30,
                Statistics = new List<string> { AVERAGE },
                Dimensions = dimensions,
                Namespace = "AWS/EC2",
                EndTime = DateTime.Now.ToUniversalTime(),
                StartTime = DateTime.Parse(startTime)
            };

data.Columns.Add(AVERAGE);
data.Columns.Add(TIMESTAMP);

var points = Service.GetMetricStatistics(reg).GetMetricStatisticsResult.Datapoints.OrderBy(p => p.Timestamp);

但直接检查警报状态会更有用。

我们已经迭代了AmazonEC2.DescribeInstancesResponse结果但到目前为止没有任何乐趣。有没有人实现过这个目标呢？

要获取警报的状态，您可以使用AmazonCloudWatch.DescribeAlarms方法。以下是有关如何获取警报状态的代码示例（在US-West-2区域）：

        var cloudWatchClient = AWSClientFactory.CreateAmazonCloudWatchClient(RegionEndpoint.USWest2);
        var describeAlarmsResponse = cloudWatchClient.DescribeAlarms(new DescribeAlarmsRequest
        {
            AlarmNames = { "the_name_of_your_alarm" }
        });
        var describeAlarmsResult = describeAlarmsResponse.DescribeAlarmsResult;
        foreach (var alarm in describeAlarmsResult.MetricAlarms)
        {
            Console.WriteLine("Alarm State = " + alarm.StateValue);
            Console.WriteLine("Alarm State Reason = " + alarm.StateReason);
            Console.WriteLine("Alarm JSON Data = " + alarm.StateReasonData);
        }
