Timing Metrics

The smallest timing unit that CloudWatch supports is microseconds; therefore timing metrics are automatically downgraded to microseconds (by dividing delta values by 1000). This conversion will also apply to custom timing metrics produced with a metric processor.

Billing

AWS bills per metric series exported, it is therefore STRONGLY recommended that you reduce the metrics that are exposed with a mapping like this:

metrics:
  mapping: |
    if ![
      "input_received",
      "input_latency",
      "output_sent",
    ].contains(this) { deleted() }
  aws_cloudwatch:
    namespace: Foo
