[ aws . events ]

test-event-pattern

Description

Tests whether the specified event pattern matches the provided event.

Most services in AWS treat : or / as the same character in Amazon Resource Names (ARNs). However, CloudWatch Events uses an exact match in event patterns and rules. Be sure to use the correct ARN characters when creating event patterns so that they match the ARN syntax in the event you want to match.

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.

Synopsis

  test-event-pattern
--event-pattern <value>
--event <value>
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--event-pattern (string)

The event pattern. For more information, see Events and Event Patterns in the Amazon CloudWatch Events User Guide .

--event (string)

The event, in JSON format, to test against the event pattern.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.

Examples

To check whether an event pattern matches a specified event

This example tests whether the pattern "source:com.mycompany.myapp" matches the specified event. In this example, the output would be "true":

aws events test-event-pattern --event-pattern "{\"source\":[\"com.mycompany.myapp\"]}" --event "{\"id\":\"1\",\"source\":\"com.mycompany.myapp\",\"detail-type\":\"myDetailType\",\"account\":\"123456789012\",\"region\":\"us-east-1\",\"time\":\"2017-04-11T20:11:04Z\"}"

Output

Result -> (boolean)

Indicates whether the event matches the event pattern.
