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
