使用 Amazon CloudWatch 监控 Aurora DSQL

使用 CloudWatch 监控 Aurora DSQL，CloudWatch 会收集原始数据并将其处理为易读且近乎实时的指标。CloudWatch 将这些统计数据保留 15 个月，有助于您更好地了解 Web 应用程序或服务性能。设置警报以监视特定阈值，并在达到阈值时发送通知或采取行动。查看以下可用于 Aurora DSQL 的使用情况和可观测性指标。

可观测性和性能

此表概述了 Aurora DSQL 的可观测性指标。它包括用于跟踪只读事务数和总事务数的指标，以提供总体工作负载特征。包括查询超时和 OCC 冲突率等可操作指标，有助于识别性能问题和并发冲突。与会话相关的指标，包括有关活动状态和总数方面的指标，可供深入了解系统上的当前负载。

CloudWatch 指标名称	指标	单位	描述
ReadOnlyTransactions	Read-only transactions	none	The number of read-only transactions
TotalTransactions	Total transactions	none	The total number of transactions executed on the system, including read-only transactions.
QueryTimeouts	Query timeouts	none	The number of queries which have timed out due to hitting the maximum transaction time
OccConflicts	OCC conflicts	none	The number of transactions aborted due to key level OCC
CommitLatency	Commit Latency	milliseconds	Time spent by commit phase of query execution (P50)
BytesWritten	Bytes Written	bytes	Bytes written to storage
BytesRead	Bytes Read	bytes	Bytes read from storage
ComputeTime	QP compute time	milliseconds	QP wall clock time
ClusterStorageSize	Cluster Storage Size	bytes	Cluster size

使用情况指标

Aurora DSQL 使用名为分布式处理单元（DPU）的单个标准化计费单位，来衡量所有基于请求的活动，例如查询处理、读取和写入。
