2. Notes#
SQS Approximate metrics 用于趋势与告警，不用于精确业务计数或财务对账。
DLQ 是独立 queue，需要单独选择或用 queue naming convention 过滤。
Approximate metrics 适合趋势和告警，不适合精确计数审计。3. ops/s Unit#
ops/s 是 operations per second。
在 SQS dashboard 里，它表示 message-related metric event 的每秒速率，不是业务交易数：
sent:
NumberOfMessagesSent / period_seconds
received:
NumberOfMessagesReceived / period_seconds
deleted:
NumberOfMessagesDeleted / period_seconds
empty receive:
NumberOfEmptyReceives / period_secondsCloudWatch 里的这些 metric 通常取 Statistic: Sum：
Sum:
当前 period 内的总次数
ops/s:
Sum / period_seconds例子:
period = 300
NumberOfMessagesDeleted Sum = 1500
ops/s = 1500 / 300 = 5所以 dashboard 里如果你看到 ops/s，本质上是在把 CloudWatch 的 period 总数换算成每秒速率，方便比较不同时间窗口下的吞吐。
