Terraform 获取AWS CloudWatch警报的地形参考
以下地形资源创建AWS cloudwatch警报,但仍处于“数据不足”状态。我相信这是因为我使用的一些维度名称(DevicePath、fstype)可能不正确。我知道名称MountPath和InstanceID是正确的,但无法验证其他两个(DevicePath、fstype)。AWS分别将这些维度称为路径、设备、fstype和主机,但是,无法找到terraform所称的参考Terraform 获取AWS CloudWatch警报的地形参考,terraform,amazon-cloudwatch-metrics,cloudwatch-alarms,Terraform,Amazon Cloudwatch Metrics,Cloudwatch Alarms,以下地形资源创建AWS cloudwatch警报,但仍处于“数据不足”状态。我相信这是因为我使用的一些维度名称(DevicePath、fstype)可能不正确。我知道名称MountPath和InstanceID是正确的,但无法验证其他两个(DevicePath、fstype)。AWS分别将这些维度称为路径、设备、fstype和主机,但是,无法找到terraform所称的参考 resource "aws_cloudwatch_metric_alarm" "Low_Disk_Space_For_ro

将TreatMissingData添加到资源体

**TreatMissingData = "notBreaching"**
actions_enabled = true
alarm_actions = ["arn:aws:sns:xxxxxx"]
ok_actions = ["arn:aws:sns:xxxxxx"]
}
为了使这项工作,你需要
- 将
更改为MountPath
path
- 删除
,而是添加DevicePath
device
- 添加
和ImageID
InstanceType
维度字段
(注意-用您自己的值替换这些值。您应该能够从AWS控制台上的Cloudwatch MetricsCWAgent
部分查看它们)
主要原因是因为你把什么作为设备
将“/dev/xvda2”更改为类似(“nvme1n1”)的确切设备。您可以在CloudWatch Metrics中检查这一点
