Get data from Amazon CloudWatch

Use the Amazon CloudWatch source function to get metric events data from Amazon CloudWatch. You must create a connection to use this source function. See Create a DSP connection to Amazon CloudWatch.

Function output schema

This function outputs data pipeline metric events using the metrics schema.

For each metric in the body field, the function includes the following dimensions in addition to the ones that are part of the original payload:

  • AccountID: The ID of the AWS account associated with the metric. This dimension is omitted if the account ID cannot be retrieved.
  • Region: The AWS region associated with the metric.

The following is an example of a typical record from the read_from_aws_cloudwatch_metrics function:

{
"attributes": {
      "default_dimensions": {}
      },
"body": [
      {
      "dimensions": {
           "AccountID": "123412341234",
           "BucketName": "my-test-bucket",
           "FilterId": "EntireBucket",
           "Region": "us-east-1"
           },
      "name": "AWS/S3.4xxErrors.Maximum",
      "type": "g",
      "unit": "Count",
      "value": 0
      },
      {
      "dimensions": {
           "AccountID": "123412341234",
           "BucketName": "my-test-bucket",
           "FilterId": "EntireBucket",
           "Region": "us-east-1"
           },
      "name": "AWS/S3.4xxErrors.Sum",
      "type": "g",
      "unit": "Count",
      "value": 0
      }
      ],
"host": "aws_test_server",
"id": "2823738566644596",
"nanos": 0,
"source": "us-east-1:AWS/S3",
"sourcetype": "aws:cloudwatch:metrics",
"timestamp": 1598819400000
}

Required arguments

connection_id
Syntax: string
Description: The ID of your Amazon CloudWatch connection.
Example: "576205b3-f6f5-4ab7-8ffc-a4089a95d0c4"

Optional arguments

initial_position
Syntax: LATEST | TRIM_HORIZON
Description: The position in the data stream where you want to start reading data. Defaults to LATEST.
  • LATEST: Start reading data from the latest position on the data stream.
  • TRIM_HORIZON: Start reading data from the very beginning of the data stream.
Example: "LATEST"

SPL2 example

You can write the function using arguments in this exact order.

| from read_from_aws_cloudwatch_metrics("my-connection-id", "TRIM_HORIZON") |... ;

Alternatively, you can use named arguments in any order, and omit the optional argument if you just want to use the default value. See the "Named arguments" section in SPL2 syntax for more details. The following SPL2 example omits the initial_position argument.

| from read_from_aws_cloudwatch_metrics(connection_id: "my-connection-id") |... ;

Limitations of the Amazon CloudWatch source function

The Amazon CloudWatch source function uses scheduled data collection jobs to ingest data. See Limitations of scheduled data collection jobs for information about limitations that apply to all scheduled data collection jobs.
