适用于 RDS 的 AWS cloudwatch 警报

Question

有没有办法根据可用磁盘百分比为我的 RDS 实例在 cloudwatch 上发出警报（我知道我可以打开增强监控并且该指标在那里，但我不能在 cloudwatch 警报上使用这些指标）如果没有一个好的出路？

Answer 1

RDS doesn't report percentage of disk space free, but it does report the amount of free space available. See the list of CloudWatch metrics available for your RDS instances here .

You would need to create alarms on the FreeStorageSpace metric reported by each of your instances.

Answer 2

See an option using Enhanced Monitoring and log metrics enter link description . Basically you can turn on enhanced monitoring for RDS and then parse the JSON logs to get the usedPercentage value for the storage filesystem. This can be turned into a log metric that can be associated with an alarm.
