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

Fields

credentials

Optional manual configuration of AWS credentials to use. More information can be found in Amazon Web Services.

Type: object

credentials.from_ec2_role

Use the credentials of a host EC2 machine configured to assume an IAM role associated with the instance.

Requires version 4.2.0 or later.

Type: bool

credentials.id

The ID of credentials to use.

Type: string

credentials.profile

A profile from ~/.aws/credentials to use.

Type: string

credentials.role

A role ARN to assume.

Type: string

credentials.role_external_id

An external ID to provide when assuming a role.

Type: string

credentials.secret

The secret for the credentials being used.

This field contains sensitive information that usually shouldn’t be added to a configuration directly. For more information, see Secrets.

Type: string

credentials.token

The token for the credentials being used, required when using short term credentials.

Type: string

endpoint

Allows you to specify a custom endpoint for the AWS API.

Type: string

flush_period

The period of time between PutMetricData requests.

Type: string

Default: 100ms

namespace

The namespace used to distinguish metrics from other services.

Type: string

Default: Benthos

region

The AWS region to target.

Type: string

tcp

TCP socket configuration.

Type: object

tcp.connect_timeout

Maximum amount of time a dial will wait for a connect to complete. Zero disables.

Type: string

Default: 0s

tcp.keep_alive

TCP keep-alive probe configuration.

Type: object

tcp.keep_alive.count

Maximum unanswered keep-alive probes before dropping the connection. Zero defaults to 9.

Type: int

Default: 9

tcp.keep_alive.idle

Duration the connection must be idle before sending the first keep-alive probe. Zero defaults to 15s. Negative values disable keep-alive probes.

Type: string

Default: 15s

tcp.keep_alive.interval

Duration between keep-alive probes. Zero defaults to 15s.

Type: string

Default: 15s

tcp.tcp_user_timeout

Maximum time to wait for acknowledgment of transmitted data before killing the connection. Linux-only (kernel 2.6.37+), ignored on other platforms. When enabled, keep_alive.idle must be greater than this value per RFC 5482. Zero disables.

Type: string

Default: 0s
