【问题描述】：

我正在尝试在 SQS 显示 50 多条消息时创建警报。不幸的是，我从 terraform apply 收到以下错误。

Error: Creating metric alarm failed: ValidationError: Period (10) not supported

我在 terraform.io 中寻找值限制 => https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/cloudwatch_metric_alarm

以及 aws 文档 -> https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/AlarmThatSendsEmail.html

我的地形如下

resource "aws_cloudwatch_metric_alarm" "aggregator-threshold-ceiling-alarm" 
  count               = var.tagging_environment == "int" ? 1 : 0
  alarm_name          = "aggregator-queue-depth-ceiling-alarm"
  comparison_operator = "GreaterThanOrEqualToThreshold"
  evaluation_periods  = "1"
  metric_name         = "ApproximateNumberOfMessagesVisible"
  namespace           = "AWS/SQS"
  period              = "10"
  statistic           = "Maximum"
  threshold           = "50"
  treat_missing_data  = "notBreaching"

  dimensions = 
    QueueName = "$module.sqs_client-comm-aggregator.main-queue-name"
  

  alarm_description = "This metric monitors queue depth and scales up or down accordingly."
  alarm_actions     = ["$module.sns_cx-clientcomm-load-indicator-lambda-aggregator.topic_arn"]

【参考方案1】：

我的猜测是 您的 Amazon SQS 队列的 CloudWatch 指标会以一分钟的时间间隔自动收集并推送到 CloudWatch。 https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-monitoring-using-cloudwatch.html

对于时间段：只有您定义的存储分辨率为 1 秒的自定义指标支持亚分钟时间段。 https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/cloudwatch_concepts.html#Statistic

尝试将期间设置为 60。
