Cloudwatch 警报 4xx 错误 API 网关 Terraform

Question

我正在尝试为 API 网关设置 Cloudwatch 警报。在此示例中，我尝试使用现有的 4xx 指标，但即使 4xx 指标显示数据点，警报也永远不会触发。我正在努力寻找自己做错了什么。此时我只想在出现任何 4xx 错误（例如 404）时立即触发警报。

这就是地形。我怀疑尺寸有误，但我不确定。预先感谢！

resource "aws_cloudwatch_metric_alarm" "gateway_error_rate" {
  alarm_name          = "${local.workspace_name}-gateway-errors"
  comparison_operator = "GreaterThanOrEqualToThreshold"
  alarm_description   = "Gateway error rate has exceeded threshold"
  treat_missing_data  = "missing"
  metric_name         = "4xx"
  namespace           = "AWS/ApiGateway"
  period              = 60
  evaluation_periods  = 1
  threshold           = 1
  statistic           = "Sum"
  unit                = "Count"

  dimensions = {
    ApiName = aws_apigatewayv2_api.my_gateway.name
    Stage = aws_apigatewayv2_stage.default.name
  }
}

Answer 1

我就在不远的地方。最终的地形将尺寸从

ApiName

更改为

ApiId

，并将

unit

替换为

datapoints_to_alarm

resource "aws_cloudwatch_metric_alarm" "gateway_error_rate" {
  alarm_name          = "${local.workspace_name}-gateway-errors"
  comparison_operator = "GreaterThanOrEqualToThreshold"
  alarm_description   = "Gateway error rate has exceeded threshold"
  treat_missing_data  = "missing"
  metric_name         = "4xx"
  namespace           = "AWS/ApiGateway"
  period              = 60
  evaluation_periods  = 1
  threshold           = 1
  statistic           = "Sum"
  datapoints_to_alarm = 1

  dimensions = {
    ApiId = aws_apigatewayv2_api.my_gateway.id
    Stage = aws_apigatewayv2_stage.default.name
  }
}
