aws_cloudwatch

Send metrics to AWS CloudWatch using the PutMetricData endpoint.

Introduced in version 3.36.0.

# Common config fields, showing default values
metrics:
  aws_cloudwatch:
    namespace: Benthos
  mapping: ""

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
